Have you ever had a meal that was a little too big so you saved the leftovers? That's what solar systems do with leftover dust, rock, and ice… they freeze 'em. If that material doesn't get pulled in to make stars or planets, it continues flying around as big frozen balls of dust & rock (aka comets). Comet Leonard had a similar path (flying through space in 2021) until it had a close encounter with our sun. This encounter was so close it resulted in the eventual breakup and disintegration of Comet Leonard.
Calibrated images of Comet Leonard were provided by Blake Estes from iTelescope.net. In addition to providing access to their telescopes, iTelescope.net provides subscribing members with a combination of premium image sets (with the rights to use & post them) and webinars that show how to process them. Itelescope.net captured the images and I did the post-processing with Astro Pixel Processor, Photoshop and Topaz Denoise. Star spikes are natural.

Despite being only 5 degrees above the horizon when I imaged it, both the broad yellow tail and the fainter blue ion tail are apparent. And the tails are long - this image, taken with a 135mm lens (~200mm 35mm equivalent on the X-T10), is uncropped.
Acquisition details: Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 40 x 15 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with GIMP and Astro Pixel Processor (I removed the heavy background gradient using Astro Pixel Processor's 'remove light pollution' tool.). Taken July 13, 2020 from Bortle 3/4 skies at 11:15 pm Pacific (the beginning of astronomic dark).
It's perhaps the most obvious deep-sky object to photograph, so it was high time I had a go. With a meeting looming last Friday evening, I set up the StarAdventurer tracker in the back garden and Sony camera firing 30s subs every 2mins. By the time I returned, the clouds had rolled in but I got 55mins of light data to be working on.
The popular Pleiades star cluster from Atascadero, California. Not as dark as the less populated location in Arizona where I made the previous photo, but getting a lot of faint structure in interstellar dust with a total of 6 hours of exposure. And something I never noticed before, a faint galaxy just to the right of the rightmost bright star, shining through the dust from 280 million light-years away at a faint 16th magnitude. This could use a bit more processing to remove some artifacts, but I'm stunned by the detail.

On this night the skies were beautifully clear and I was able to capture the data to create this image of Centaurus A (aka NGC5128 or 'The Hamburger Galaxy').
This is one of the closest radio galaxies to earth and is the fifth-brightest in the sky thanks to the supermassive black hole at the centre. This black hole has an estimated mass of around 55 million solar masses and ejects cosmic rays from it's core which can be captured in images taken at different wavelengths.

My first successful astro mosaic! It's a total of 380 minutes of imagery, 11 different panels, so panel integrations average 34 minutes. The Orion, Running Man, Horsehead, and Flame Nebulae area has the most imagery behind it, as well as the Witch Head Nebula.
Imagery was acquired in 2019 and 2020 on 9 different nights from the same location under rural skies (Bortle 3/4). All subs were taken with my Fuji X-T10 and Samyang 135 mm on the iOptron SkyTracker Pro. Each sub is 60 seconds, taken at ISO 1600 with the Samyang 135mm open to f2.
I integrated individual panels using DeepSkyStacker, and used the 'remove light pollution' tool of Astro Pixel Processor to flatten integrations, which had substantial vignetting from being shot at f2. These flattened panels were then mosaiced with Astro Pixel Processor using the process outlined here: www.astropixelprocessor.com/part-3-register-normalize-int.... Curves adjustment, star reduction, and color tweaking were then done with GIMP. This image is downscaled 50%.
It's not a perfect process and the data has issues, but I'm happy with the result. It was fun to explore the less-imaged nebulosity between the Orion and the Witch Head Nebulae, and around Saiph.
I'm sure I'll keep tinkering with this, and I still plan to shoot the entirety of Orion this winter, but this is a nice mosaic in and of itself, so I wanted to post it.
Aug. 2021 update: I've been looking through my astro photos, ramping up for some imaging this fall and winter (hopefully I'll complete this Orion mosaic). I decided this image could use a little lightening.

M31 ist die uns nächst gelegene Spiralgalaxie in ca. 2,5 Mio Lichtjahren Entfernung. Sie ist die größte (massereichste) Galaxie in unserer lokalen Gruppe und wie unsere eigene Milchstrasse auch eine Spiralgalaxie. In einigen Milliarden Jahren wird sie mit unserer Milchstrasse kollidieren (d.h. eigentlich sich durchdringen und gravitativ wechselwirken).
In klaren und dunklen Herbst- und Winternächten ist sie leicht mit bloßem Auge im Sternbild Andromeda zu sehen.

The Orion Nebula (NGC 1976, M42) taken on a cold November night.
> The Orion Nebula is a diffuse nebula situated in the Milky Way, being south of Orion’s Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. — Wikipedia
This image was created from around 30 exposures between 40 seconds and 3 minutes long, at ISO 800, Stacked in AstroPixelProcessor. I used the same data as in the original I shared, but using AstroPixelProcessor instead of DeepSkyStacker and some alternative processing. I prefer the colours in this one!
I used a SkyWatcher Esprit 100 telescope on a HEQ 5 Pro tracking mount, and the Nikon z 50 which coped admirably.

NGC 7822 is an emission nebula located in Cepheus, about 3,000 lightyears away.
It’s a violent, chaotic deep-sky region where young stars are being born, their powerful radiation ionising the surrounding gas and causing it to glow.
These energetic stellar winds are also carving out the dusty streams and pillars seen throughout the nebula.
Within these dark, dusty regions, new stars are likely being born, but the powerful radiation that’s fuelling NGC 7822’s light emission is also destroying the cosmic gas and dust necessary for stellar birth, effectively cutting them off at the source.

This image was made from a combination of data taken in 2014 and 2017 using a Takahashi FSQ106 with a SXV-H9 in 2014 and my TMB92ss with a QSI583ws in 2017. Using recent improvements in astropixelprocessor I was able to finally combine this data into one result improving details in the central part of the nebula.
Processing was fully done using astropixelprocessor and adobe photoshop.
This region is quite interesting and I think my next project will be to expand the range around the nebula because there is much more nice nebulosity in this region.

www.astropixelprocessor.com/complete-lrgb-tutorial-of-ngc... Small Magellanic Cloud, NGC292, LRGB composite shot with iTelescope T08. Total exposure time is 13,25 hours. data was completed processed with Astro Pixel Processor from calibration of the raw exposures to the final stretched star color calibrated image by me.
There's something about the combination of both pink and blue colors from a single nebula that I find really interesting. This is the Trifid Nebula (aka M20) located in the Sagittarius Constellation near the core of our Milky Way galaxy.
For years shooting with a dslr camera, I saw this nebula appear really small against the vast Milky Way core. Now that I'm using telescopes and I can capture the rgb colors independently, the results are very different. With about two hours of total capture time using iTelescope's T32 wide deep field telescope based at the Siding Spring Observatory in Australia, I shot 24 images (over 3 separate nights of shooting) before processing them with Astro Pixel Processor and Photoshop.
Sh2-157 and Sh2-162 are HII regions in the constellation Cassiopeia. The bubble is a shockwave created by an unstable star nearing it's death as a supernova. The shockwave collides with the nearby cold gas, sweeping it up and causing it to glow.

I almost continued work on my Orion mosaic last night, but ultimately decided to image the Cone Nebula region again. My previous image of this area from a year ago always bugged me - the focus was off and I didn't like the processing.
So I reshot this area last night - this time my focus was on, the skies were better, and I like the color I ended up with more. Not as happy with the framing, but at least the data is good so I can potentially add more data to this at a later date to improve framing or create a mosaic.

One of my favorite regions of the sky - the Dark Shark Nebula (LDN 1235), LDN 1251, and the Wolf's Cave Nebula (vdB 152). It's a tricky region to process - the dust is faint and the stars are plentiful. If I shoot this again with the my Samyang 135, I think I'll stop down to f 2.8 to flatten the field and shoot 90-120 sec subs. I had problems with the not-too-flat field in post processing. I've cropped it to minimize the non-flat-field color artifacts.

Nov. 2020 update: I added my Sept. 26 2019 imagery (50 x 90 seconds, better color) to my 2020 imagery (84 x 60 seconds, better skies). There's still some color weirdness, but the addition of the 2019 with better color helped modulate the color weirdness of the 2020 data. I might still end up cropping it, but at least the color is a bit better. Perhaps I'll shoot this area again next August or Sept.

OMGOMGOMG. I had a chance to try out the new Celestron RASA 8! For those of you who are familiar with our weather in Seattle, you'll understand our excitement about getting a 4-day stretch of PERFECT (and cold) weather during new moon.
Because the RASA is f/2, I collected a TON of data which I will process in the coming cloudy days, but I wanted to post this one photo of M42 ASAP because it is a true testament of what this astrograph can do.
This is a mere ~1 hr of data from a Bortle 8-9, urban sky. For you f/7 imagers out there, YOU would have to expose for 14.4 hours to get the same signal to noise! To help with the massive amount of light pollution in my area, I used the Celestron RASA LPR filter that just threads in to the top of the RASA corrector.
I'm VERY excited about the potential of this scope. It's an extremely fast, high performing, and affordable scope, AND it's probably one of the easiest systems I've used.
More tips in future posts (including a "how-to" on flat taking), but here's a good one to start out with: Make sure you have the right spacing between the camera and the RASA corrector for best optical performance. Incorrect spacing will really hurt imaging quality. If your stars are in focus in one part of the field, but out of focus elsewhere in the field, you should suspect that spacing might be the culprit.

This is the Messier 101 (The Pinwheel Galaxy).
The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy 21 million light-years (6.4 megaparsecs)[5] away from Earth in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781[a] and was communicated that year to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries.
On February 28, 2006, NASA and the European Space Agency released a very detailed image of the Pinwheel Galaxy, which was the largest and most-detailed image of a galaxy by Hubble Space Telescope at the time.[10] The image was composed of 51 individual exposures, plus some extra ground-based photos.

The beginning of my winter astro project, a test to see if my process will work. So far so good - I'm impressed by how well Astro Pixel Processor blends images together.
This mosaic consists of the 6 panels that I have of the Orion region so far - all taken with my Fuji X-T10, Samyang 135, and iOptron SkyTracker Pro over the last couple years under Bortle 3/4 skies. I've downscaled the mosaic by 50% for upload to Flickr.
I plan to image the entire Orion constellation this winter, so that every area has at least 30 x 1 minutes of data behind it, preferably more like 60 x 1 minutes of data.
