I have now purchased a QHY5L-II Mono camera. New challenges come with this:

 

1. Bloody dirt on the sensor!! Apparantly you would be lucky to buy new camera without dirt. Now I did try to clean it with an aircan but it all it did was split them into little pieces, still its better than the big blotches.

 

2. Newtonian rings. This is caused by the light diffraction on the glass protection cover over the CMOS sensor. Effect is horrible.

 

So to overcome the above two problems, I allow my image capture to drift a little bit. Then, without changing the gain/exposure settings I unfocus the PST on the middle of the sun surface until all dirt and newton rings show up against a completely white unfocussed background. Autostakkert 2 can then use this as a Master Flat and eliminate the rings and dirt very effectively. And so for my first complete proccessed image, I obtained this image. Of course, I am in early stages of learning to image with this camera but I am very happy with the vast improvement in detail that it captures compared to my DSLR which I was using up until now.

-

NGC 1333 is a reflection nebula located in the northern constellation Perseus, positioned next to the southern constellation border with Taurus and Aries.[3] It was first discovered by German astronomer Eduard Schönfeld in 1855.[4] The nebula is visible as a hazy patch in a small telescope, while a larger aperture will show a pair of dark nebulae designated Barnard 1 and Barnard 2.[5] It is associated with a dark cloud L1450 (Barnard 205). Estimates of the distance to this nebula range from 980–1,140 ly (300–350 pc).[4]

Object Details: The attached composite shows images of the large sunspot AR2978 in various wavelengths and has been annotated with a sample NASA shot of the Earth for size comparison.

 

Consisting of a huge core larger than our entire planet, in spite of it's immense size, it's been fairly quiet; however it's size did enable the prediction of it's arrival on the southeastern limb back on March 25th as seen by Nasa's helioseismic far-side imaging.

 

Indications of a short 'light-bridge' like structure can be seen at the top of the spot, and like the faculae, tends to be more readily visible in the UV image. Although AR2978 has rotated off the visible surface today, helioseismic far-side imaging is once again indicating the presence of a huge back-side active region. In this case the current theory is that it may be the previous sunspot AR2975.

 

If this is indeed the case, assuming it survives a complete rotation around the solar disk we may be in for a treat since, as mentioned in the text accompanying the link below,

 

'... AR2975 released several solar flares this week as it traversed the disk; including an M9.4 and a X1.3 class. These resulted in 'cannibalistic' coronal mass ejections (CMEs) and a geomagnetic storm with aurora visible in the northern tier states of the US ...'

 

I was fortunate to catch AR2975 just prior to it rotating off the limb on April 4th as shown here:

Image Details: Taken by Jay Edwards on the afternoon of April 5, 2022 from the RoR observatory I built at my home here in upstate, NY using -

 

at upper left: An Orion ED80T CF (i.e. an 80MM, f/6 triplet, carbon-fiber refractor) with a 0.8x Televue field flattener / focal reducer, Kendrick film solar filter and an unmodded Canon 700D DSLR controlled by APT, it is a stack of 32 frames taken at ISO 100 and with a 1/4000 second exposure;

 

at top center: A Celestron 'short-tube' 80MM, f/5 refractor with a Thousand-Oaks glass solar filter and an ASI290MC planetary camera / auto-guider controlled by SharpCap Pro, this is a stack of several hundred frames selected from several thousands shot at 0.768 milliseconds, and

 

At upper right & below, a vintage 1970, 8-inch, f/7 Criterion newtonian reflector with a home-made Baader (visual grade material) off-axis solar filter and the aforementioned ASI290MC. As with the 80MM Celestron shot, they are stacks of several hundred frames, in this case at various exposures, selected from short video clips consisting of several thousand.

 

In both cases the ASI290MC was placed at prime focus and was controlled by SharpCap Pro and all scopes were tracked using a Losmandy G-11 goto mount running a Gemini 2 control system. The images at bottom also utilized a set of specialized planetary filters (Infrared, Ultraviolet & Methane) in addition to the over-the-aperture solar filter. As shown here the entire composite has been resized down to HD (one-third of it's original resolution).

 

Hoping the next week or so brings AR2975 back into view and brings with it some wonderful auroral activity - stay tuned !

First attempt at this. I may need longer exposures, and I think my framing could be moved to get more interesting stuff. There's a bit of noise too, and I think that may be from high-level clouds. Will try again.

Test shot of Whirlpool galaxy using ZWO ASI224 MC Camera, connected to Celestron NexStar 6 SE Telescope. Video was captured in SharpCap, processed in Registax 6. It was touched up in Lightroom and Photoshop (PS).

Decided to go after Venus super fast before astro dark. Unfortunately clouds rolled in right as I started my deep sky images, but I at least got a good planetary pic. Although this was the night Venus was in the Pleiades cluster, my focal length/FOV and lack of tracking on my ETX meant that I couldn't get the rest of the cluster. Captured on April 3rd, 2020.

The Koi Fish Galaxy, officially known as NGC 4559 or Caldwell 36, is an intermediate spiral galaxy located in the constellation Coma Berenices, approximately 29-30 million light-years from Earth. It's dubbed the "Koi Fish Galaxy" by some due to its appearance in astrophotographs, where its extensive spiral arms, featuring bright blue star-forming regions and intricate dust lanes, can evoke the patterned scales of a koi fish. This galaxy is an active site of star formation and has hosted at least one recorded supernova.

There was a lot of activity on the Sun that day! I decided to try to create a prominence animation for the first time. This short video covers the period from 10:51 to 12:19 UT. I shot a video every 10 minutes and after stacking I manually aligned each stacked image in Lightroom then created the video with Movie Maker.

 

There are small needle prominences that come and go and the large prominence changes morphology. I also noticed that there changes to the filaments that were present on the disc as well. There is a small active region - AR12971 - which is visible on the disk of the Sun and the filaments around this area were also changing a lot during this 90 minute period. The video repeats a few times so you can watch different regions changing.

Object Details: As Saturn approaches opposition on August 2nd this year it has begun to show what is known as the Seeliger effect - the brightening of rough objects, or objects made of many particles (e.g. Saturn rings), when they are illuminated from directly behind the observer. Combining the effects of coherent backscattering and shadow hiding, this results in an apparent brightening of the rings with respect to the planet itself. This effect peaks at the time of opposition and can be readily apparent for several weeks prior and following that date.

 

Image Details: Taken by Jay Edwards on July 27, 2021 at the HomCav Observatory using a 3X Televue barlow with set of specialized planetary filters on a vintage 1970, 8-inch, f/7 Criterion newtonian reflector with an ASI290MC' planetary camera / autoguider'. Like other planetary images posted previously, the scope was mounted on and tracked with a Losmandy G-11 running a Gemini 2 control system.

 

As presented here, the individual shots have been resized down to 75% of their original size and processed using a combination of Registax & Paint Shop Pro.

 

With Saturn reaching only 29 degrees above our southern horizon, and this particular evening being bathed in wildfire smoke, I was pleasantly surprised at the results and am hoping the weather permits imaging it during this year's opposition.

Object Details: Getting a break late Monday night / early Tuesday morning from the thunderstorms that have been plaguing our part of upstate, NY for many weeks I decided to try some planetary imaging.

 

While getting one of our longer focal length scopes configured for 'higher magnification' shots, I noticed the Moon just starting to rise - and due to the smoke from the wildfires thousands of miles to our west - it appeared blood red, as if in a deep mid-eclipse. Having not seen Saturn nor Jupiter yet this year I proceeded to shoot both (although I have yet to examine or process those video clips a quick screen shot I grabbed showing single frames during the imaging session can be found the the link attached here - www.flickr.com/photos/homcavobservatory/51339199976/

 

As Jupiter transited about 3 AM EDT I noticed that the moon, 18 days old, 88% illuminated and now 37 degrees above the horizon was enveloped in an incredibly colored yellowish / brownish halo. With many lunar features being relatively large in apparent size, although I would normally not image the moon at such a 'high mag' as the scope was set up for at that time (i.e. the FOV was only about 3 x 2 arc minutes), I figured given the situation I'd give it a shot.

 

Being just past full, the terminator was somewhat smallish at the time, but as I scanned along it with the scope two craters in particular stood out. Therefore, the attached composite shows the craters Atlas (left) and Hercules (right). Imaged with a one-shot-color camera, the left hand image shows (what I assume) was the result of the wildfire smoke colorizing the entire scene in a strange hue, while the right side shows an extraction of the luminance channel from this image. Since I mainly shoot for reasons of 'pure art', although I often balance & adjust the color (e.g. hue, saturation etc.) in most astronomical images I produce for an end result that I find visually pleasing, in this case I did not modify it at all, and only applied wavelets & an unsharp mask for sharpening. As such the color shown in the left hand shot is 'right out of the camera'.

 

I've run across this type of 'wildfire smoke induced colorization' of the moon previously, in the summer of 2019 as my friend and I were imaging - a link to which is attached here

 

www.flickr.com/photos/homcavobservatory/48324332996/in/al...

 

as well as when we had just returned from the above mentioned 2017 TSE. Fortunately we were able to avoid the smoke while in Idaho for the eclipse, but two weeks later after returning to upstate, NY, like this past Tuesday night, I found the rising moon also deep red from the wildfire smoke - an image of which can be found at the link attached here -

 

www.flickr.com/photos/homcavobservatory/36866168426/in/al...

 

With a lava flooded floor which buries the central peak, the crater Hercules is 69 km (43 mi.) in diameter with a very prominent 14 km (9 mi) diameter crater (Hercules G) super imposed on it at upper left of center. Atlas is 87 km (54 mi) in diameter with a fractured floor. In spite of the wildlfire smoke, I was pleasantly surprised to see the amount of detail in this fracturing that was visible once the images were stacked and processed. It is still somewhat controversial as to whether this fracturing was a result of geologic faulting of the rebounded surface, or volcanism, both following the initial impact. Although certainly not water related, it reminded my friend and I of either river channels, or collapsed lava tubes that we walked thru in Hawaii and Idaho while on vacations chasing the Total Solar Eclipses (in 1991 & 2017 respectively).

 

Image Details: Taken by Jay Edwards at 04:03 EDT on July 27, 2021 at the HomCav Observatory, since I was setup for Saturn & Jupiter that evening this image was also taken using a (vintage 1970) 8-inch, f/7 Criterion newtonian reflector with a 3X Televue barlow and an ASI290MC 'planetary camera / autoguider'. As usual, the scope was mounted on and tracked with a Losmandy G-11 running a Gemini 2 control system and the camera was controlled by SharpCap Pro.

 

Since humans tend to see detail in images via the brightness & contrast, as opposed to the color (and to eliminate the colorization I assume was induced by the wildfires), I have included a version of the 'one-shot-color' image which shows just the lightness channel, which has been separated from the Hue & Saturation.

 

As presented here, the shots have been processed using a combination of Registax & PaintShopPro and the entire composite has been resized down to HD resolution.

 

I'm looking forward to seeing how the shots of Jupiter and Saturn I took that evening appear once they are stacked & processed.

 

Wishing clear, calm & dark skies to all !

3.5 hours of data collected on this. Nothing short of frustrations along the way with software problems, calibration frame issues, laptop not wanting to keep up.

 

First galaxy imaged with the 269c. I'm really impressed how it's turned out considering I'm bortle 5, no filter used and the fact its millions of light years away!!

Taken on 10 October 2018 at 18.25 am BST, with Celestron NexStar 6SE SCT and NexImage 5MP Camera. AVI video captured in SharpCap and processed in Autostakkert 2. Touched-up in Lightroom.

 

Having long passed its opposition on Earth's mid northern summer, it is now much smaller, but some surface details can still be seen. The global sandstorm has now settled completely.

I need to find a way to take better flat frames, this image was subject to a wretched double gradient which made processing rather awkward. I'm pretty sure the origin of this was in the flat frame (actually i should analyse the master flat to test this out...)

 

I had been having issues with a definite banding across the centre of the image, but after much headscratching and trial and error experimentation I managed to work out that that was introduced by some poor bias frames.

 

What a minefield astrophotography can be! Still the result is ok, though I should have used longer subs.

Object Details: On September 21, 2022, the last day of summer in the northern hemisphere, mother nature had a parting gift for those of us who are solar aficionado's as two massive sunspot groups began to rotate onto the Earth facing side.

 

Shown in the images in the attached composite seething with activity & with cores larger than the entire Earth, AR3105 (right) & AR3107 (left) are accompanied by huge amount of faculae (brighter & hotter regions surrounding the groups themselves).

 

Having survive a complete rotation around the Sun, AR3105 is actually the return of a previous group (then known as AR3089, as it is traditional to renumber active regions upon their return for a another pass of the Earth facing side of the solar disk). As of today these groups are rotating off the Earth facing side while another larger active region is rotating on.

 

Should flaring occur and release any Earth directed Coronal Mass Ejections & weather and other conditions are permitting, we may experience a wonderful display of the Northern Lights. However aurora aficionados will be quick to note that even should there not be solar flares & their associated CMEs in the offing, during the first weeks of autumn, cracks form in Earth's magnetic field (known as the "Russell-McPherron effect") and at these times even the slightest solar wind may result in geomagnetic activity - it's aurora season !!! :)

 

Image Details: The images making up this composite were taken by Jay Edwards on early afternoon of Sept. 21, 2022 through high clouds with average seeing and below average transparency from the RoR observatory I built at my home here in upstate, NY using:

 

At left: A vintage 1970, 8-inch, f/7 Criterion newtonian reflector with a home-made Baader (visual grade material) off-axis solar filter and an unmodded Canon 700D DSLR at prime focus controlled by APT, meant simply as a reference it is a stack of seventeen frames taken at ISO 100 and with a 1/125 second exposure;

 

At right and below: The same 8-inch, f/7 Criterion newtonian reflector and a home-made Baader off-axis solar filter but in these cases with a ZWO ASI290MC planetary camera / auto-guider at prime focus and a set of specialized planetary filters. They are stacks of several hundred frames, at various exposures ranging from 1.2 to 24 milli-seconds and gain settings of 110 and 300, selected from short video clips consisting of several thousand.

 

The DLSR was controlled by AstroPhotographyTool (APT), the ASI290MC by SharpCap Pro and the scope was tracked using a Losmandy G-11 goto mount running a Gemini 2 control system. The images also utilized a set of specialized planetary filters (Infrared, Ultraviolet & Methane) in addition to the over-the-aperture solar filter. As shown here the ASI290MC images are at their original resolution while the DSLR shot has been resized down, and the entire composite is shown at three X HD (i.e. 5760 x 3240) and the bit depth for the DSLR shot has been lowered to 8 bits per channel.

I realized that the universe is expanding. With the SAMYANG 135mm F2 + ASI 662MC, the supernova SN 2025rbs that occurred in NGC 7331 was only faintly visible. The resolution was insufficient.

Nearby was Stephan's Quintet of Galaxies. According to Wikipedia, four of the five galaxies—NGC 7317, 7318A, 7318B, and 7319—have a redshift of approximately 6,600 km/s, placing them about 290 million light-years from Earth.

On the other hand, the bluish NGC 7320 has a very small redshift (approximately 790 km/s) and is relatively close to Earth, at approximately 39 million light-years away.

 

commons.wikimedia.org/wiki/File:Stephen's_Quintet.jpg

 

The wavelength shift difference caused by redshift is approximately 12 nm when using 550 nm green as a reference, which is sufficient to explain the noticeable color difference. The Stephan Quintet may serve as an excellent example to visually demonstrate the expansion of the universe.

I would love to try this with an apo rather than an achromat, but I currently figure the extra detail afforded by the Evostar makes up for the halos round the bright stars. I'm even starting to get accustomed to the pearl effect of once the image has been stretched!

This image is a combination of image data taken a few nights last week, with image data that I had collected last year.

 

I don't use a stacking program for images taken though my telescope. Instead, I push the brightness and contrast of every image, and carefully align them by hand, and stack them as layers in Paint Shop Pro. I save them in stacks of 10, and then stack the 10s the same way.

 

I also don't use dark frames or flat frames or any other frames other than the images themselves.

 

When it comes to guiding, I do that by hand too. I stick a QHY camera down an off-axis guider tube and run that video into a laptop. Then I bring up either Sharpcap or NINA, and put a bullseye overlay over the video. Then I watch which way the guide star drifts, and push buttons on my hand controller. So now i can take longer exposures, and it seems to work just fine, as all of my 200 second images had nice round stars.

Update: July 10, 2021 - With several days of intense thunderstorms here this past week, one of which caused a 36 hour blackout at my home, I used some of the time to drain my laptop's battery to process a quick image of the globular cluster M56 which I shot on the evening of July 4th hours after the solar images attached here. Therefore, please find attached below a link to the results of that data. With power now restored, I hope to be able to open my observatory again and continue imaging as soon as the weather allows.

Object Details: On Sunday July 4th I was fortunate to catch the massive sunspot AR 2835 as it was beginning to rotate off the Sun's visible surface. I was also able to image this group on July 2nd but have yet to examine that data - a screenshot of which is attached here:

www.flickr.com/photos/homcavobservatory/51285875171/

 

One of the reasons I processed the attached 'out of chronologic order' was that, as luck would have it, at the time of the attached it's gigantic dark core (umbra) was splitting into two. The attached composite shows how it appeared in various wavelengths using both short and longer lengths scopes.

 

When processing the images the 'light-bridge' bisecting the core is readily apparent and due to it's relative brightness was the first thing I happen to notice when examining the infrared shot. The ultraviolet image displays the large amount of plage & faculae in the surround area quite well (i.e. the brighter, hotter regions associated with the active region). As can be seen in the attached, this active area is much larger than the Earth, and it will be interesting to see if it can survive a complete solar rotation.

 

Image Details: The attached was taken by Jay Edwards at the HomCav Observatory at my home here in upstate, NY on May 19, 2021. The top images were taken with a lum filter, while those at the bottom used infrared (IR), ultraviolet (UV) and methane (CH4) filters (all in addition to an over-the-aperture' off-axis home-made Baader material white light solar filter).

 

The full disk image, utilizing a Canon 700D controlled by APT & a full aperture Kendricks light light filter on an ED80T CF (i.e. an Orion 80mm, f/6 carbon-fiber triplet apochromatic refractor), and a 0.8X Televue field flattener / focal reducer, is meant merely as a reference for location and it is a single frame shot at 1/4000 and ISO 100. For additional reference a sample image of the Earth was added to show size comparison to the 8-inch shots.

 

The 'closeup' 8-inch shots were taken using an ASI290MC 'planetary camera / auto-guider' controlled by SharpCap Pro on a vintage 1970, 8-inch, f/7 Criterion newtonian reflector with the above mentioned homemade, off-axis Baader white-light solar filter. Shot as video clips, each is a stack of best several hundred frames out of a total of tens of thousands of frames recorded that afternoon.

 

Both of these scopes are mounted on and tracked by a Losmandy G-11 running a Gemini 2 control system and the images were processed using a combination of AS3, Registax & PSP. The UV, IR & CH4 images have also been duplicated and having then had their luminance channels extracted, are placed next to their corresponding 'one-shot-color' images.

 

Processed in a combination of Astrostakkert, Registax & PaintShopPro, as presented here the composite has been resized down to 2X HD resolution and the bit depth lowered to 8 bits per channel.

Composite image made by combining two separate output from different exposure videos.

 

Taken on 29 November 2019, at 23.23 UTC (overexposed) & 23.17 UTC (normal exposure), with Celestron NexStar 6 SE SCT and ZWO asi224mc Camera. Video captured in SharpCap, stacked in AutoStakkert, then processed in PSP8, Registax 6 and LR. The moons were copied from the overexposed image & pasted onto the enlarged normal exposure image, & tidied.

 

Uranus has 27 known satellites, but only 5 are large enough to be relatively easily captured with a backyard amateur telescope. The names of these satellites are chosen from characters in the works of Shakespeare and Alexander Pope

 

The Uranian satellite system is the least massive among those of the giant planets & have relatively low albedos; ranging from 0.20 for Umbriel to 0.35 for Ariel (in green light). The moons are ice–rock conglomerates composed of roughly 50% ice and 50% rock. The ice may include ammonia and carbon dioxide.
