Here is the Cone Nebula and Fox Fur Nebula in H-Alpha.

I used a modified Canon EOS Rebel T3i DSLR through the William Optics RedCat 51 telescope for this one.

3 Hours and 15 Minutes total at ISO 1600. Riding along the portable iOptron SkyGuider Pro.

I shot a video this night, but 95% of my time was spent dealing with the other rig that was running. Funny, out of the two, this one produced a better result!

Processing Steps:

Preprocessing: FITS data > Image Calibration > Cosmetic Correction > Subframe Selector > Debayer > Select Reference Star and Star Align > Image Integration.

Linear Postprocessing: Dynamic Crop > Dynamic Background Extractor (subtraction to remove light pollution gradients and division for flat field corrections) > Background Neutralization > Color Calibration > Blur Xterminator > Noise Xterminator.

Nonlinear Postprocessing: Histogram Transformation > Star Xterminator to decompose into Starless and Stars Only images.

Starless image > Histogram Transformation > Noise Xterminator > Local Histogram Equalization.

Apply a First Curves Transformation as appropriate to boost the blue signal from the galaxy's arms. Apply an RGB Split. After adjusting the weights for the individual RGB components (noting that the R serves as both the L channel and the red channel when using an OSC camera), apply LRGB Combination to get a blue boosted image.

Apply a Second Curves Transformation as appropriate to boost the red signal from the galaxy's core. Apply an RGB Split. After adjusting the weights for the individual RGB components (noting that the R serves as both the L channel and the red channel when using an OSC camera), apply LRGB Combination to get a red boosted image.

Use Pixel Math to combine 0.5 x red boosted image + 0.5 x blue boosted image to get a Composite image.

Use Pixel math again to combine 0.75 x Composite image + 0.25 x an HDR Multiscale Transform-modified Composite image to get a New Composite image.

Process the New Composite image with Curves Transformation using color masks.

Apply Histogram Transformation and Local Histogram Equalization to get a Final Starless image.

Use Pixel Math to rejoin the Final Starless image with the Stars Only image (modified by a Morphological Transformation if needed) to get a rejoined image.

Rejoined image > Topaz Labs > DeNoise AI > Gigapixel AI.

Use Pixel Math to combine 0.25 x non-AI Composite + 0.75 x Gigapixel AI = Final Result.

I'm somewhat, not completely happy, with this one. Pulling out the dark nebulae and dust among all of the stars, with a not-completely-flat field and a light pollution gradient from shooting fairly low, was tricky.

I plan to shoot this extent again 1) when it is higher in the sky later this year, 2) possibly with 90 sec subs instead of 60 sec (although tracking was spot on with a 90% keeper rate at 60 sec), and 3) I might experiment with PixInsight to better emphasize the dark nebulae while deemphasizing the stars.

April 26 update: Cropped

Aug 8 update: Reprocessed using raw instead of out-of-camera jpeg. Definitely some advantages to using raw.

Aug 26 update: Reimaged when closer to zenith, 54 x 60 sec this time, the two versions are extremely similar (so I just replaced the older with this one) although this one has the edge in that dust cloud representation is more accurate. Processing with this cleaner data was much easier, and involved much less manipulation.

Sept 13 update: Reprocessed with Astro Pixel Processor. I like the colors a bit better, and after several reprocesses I've decided to leave the dust cloulds fairly dim, since I don't like how it turns out when I stretch too far. This is just a tricky extent - the dust is so dim. Maybe I'm finally going to leave it alone. I'm excited to tackle the Dark Shark and Wolf's Cave nebulae widefield again, but am going to reshoot since I don't have raw files.

Oct. update: Alright, I wasn't done. I couldn't help but give it another try. The nebulosity is now a bit brighter, the color of the iris is bluer, and the stars slightly more reduced. I also upped the contrast and saturation of the Ghost Nebula. Maybe I'm done now.

April 2020 edit: Still wasn't done. I upped the brightness and contrast of the dark nebulae a bit more.

It'd been awhile since I'd been astrophotographing - felt great to be out under the stars and a smokeless sky. Fall is a excellent time for widefield astrophotography in the western US - there's a decent amount of astronomic dark, plenty of clear nights, temperatures aren't too cold, and quite a few interesting widefield subjects are available.

My goal with this small mosaic (only 2 panels) was to capture both the Fireworks Galaxy (NGC 6946, tiny here, bottom left) and the Elephant Trunk Nebula (IC 1396) in the same extent, with all of the interesting nebulosity in between, most notably the dark nebula Barnard 150 (AKA the Seahorse Nebula) in the lower left, one of my favs.

Surprisingly, I didn't detect much of the red emission Flying Bat Nebula (Sh2-129, center), part of which actually appears bluish (?, at first I was excited that I might have detected the Giant Squid Nebula (OU4), but nope, the blue is not in the right place). Previously I had captured Sh2-129, albeit faintly, with this same set up in the same location.

Part of the reason for this is that I stopped my Samyang 135mm down a half stop to f 2.4 (which I usually shoot wide open at f 2), not to tighten up stars, but to flatten out the heavy vignetting a tad. It did make a difference, but I did also notice that the Elephant Trunk Nebula didn't show up as strongly as expected based on my previous imaging of it. I'm still undecided whether I'll stay with f2 or move to f2.4, might depend on the subject.

There is a decent amount of what appears to be blue reflection nebulosity around star HD 198793 in the upper left quadrant; looking at widefield images of others, I can also see this faintly, but I haven't been able to find any closer images of it yet and it isn't cataloged in my astronomy app (SkySafari 6 Plus). It's possibly a processing artifact although it doesn't appear to be one.

This image is a composite of four emission nebulae, clouds of star-forming gas and dust that are illuminated by the newborn stars they host. Each of them are included in the Sharpless Catalog of emission nebulae compiled by Stewart Sharpless in the 1950's. The individual images were captured over a period of four clear nights in Seattle, Washington, using an Ha narrowband filter to suppress light pollution by only admitting light at wavelengths emitted by the nebulae.

From top-left to bottom-right, the nebulae and integration times are as follows:

SH2-86 in Vulpecula (200 mins)

SH2-129 in Cepheus (235 mins)

SH2-126 in Lacerta (250 mins)

Almost a year has passed since my astrophotography trip to Italy. As spring is in the air again, it is time to refresh my memories of this beautiful journey.

This image was taken at one of the most photographed spots in Tuscany. You can find thousends of daylight images from this place, but despite its perfect orientation, I found no Milky Way nightscapes.

Light pollution probably is the reason why even local nightscapers do not shoot there at night, but even with very high humidity, I found it manageable with my light pollution filter.

I am glad that my planning proved to be correct and enabled me to capture my intended composition.

Located in the tail of the constellation Scorpius are the Messier open clusters referred to as M6 and M7. At this time of the year, from the Northern Hemisphere, you need to view these clusters early in the morning, after 2:00 A.M. is best.

From my location, in Pennsylvania, these clusters are difficult objects to photograph in any type of detail. Sky glow, mountains and trees all work against me in getting a nice photograph.

This is a 25 shot panorama of the early season Milky Way rising above the stromatolites of Lake Thetis, 2.5 hours north of Perth in Western Australia.

Drove out into the middle of the desert, lived off the grid for 4 days in some of the darkest skies the United States has to offer, and all I got was this lousy picture.....

.....just kidding, including the timelapse photos I took I have nearly 1,700 pictures to go through and edit. The Goblin Valley area of Utah is an amazing place, stay tuned for more....A LOT more. Easily the best photography trip I've ever taken.

For this photo I took one shot for the foreground and one shot for the sky, using my Nikon D600 and Rokinon 24mm f1.4 lens on my iOptron Skytracker mount, For the sky the mount was turned on, 4 minute exposure at ISO 800 and f3.2. Foreground is a 1 minute exposure at ISO 800 and f4. Merged and processed in photoshop/lightroom.

The annual ‘Perseid Meteor Shower’ or ‘Perseids’ peak happens once per year, although once you have witnessed it the memory will stay forever! Each year I find myself planning ahead in excitement to potentially capture these shooting stars streaking through our atmosphere.

Every other year I tend to aim my camera at the Milky Way to capture the odd meteor streak past. However last night I aimed straight into the epicentre from where the "shooting stars" arrive from, which is the constellation Perseus. This photo is a combination of all the meteors I captured over a solid 2 hr period between 11pm-1am between 11th – 12th August. There was on average a bright meteor illuminating the sky every 10 mins or so, which was a very active sky!

It was a lonely but memorising few hours standing alone in the pitch dark of night but I am pleased to have made the effort last night. Especially because it has been heavily clouded & raining ever since! Weather conditions are set to worsen so it may have been the only few hours possible for me to capture the 2021 Perseid Meteor Shower over Ireland. It’s lucky moments like this that I’m grateful for amongst many other failed photography trips throughout the year 🙏

Hi Folks,

Though the data was taken in November of 2021, this is my first image processed and published on my website for this new year!

This is a narrow field shot of NGC 1499, The California Nebula - which is located about 1,000 light-years away in the constellation of Perseus. This image is the result of 10 hours of integration in narrowband. It was shot on my Astro-Physics 130mm Platform with the CEM60 mount and the ASI2600MM-Pro camera.

The story of this image along with extensive processing details can be seen at:

De hay el color rojizo. lo que te obliga a exposiciones mas largas y un mayor numero de capturas, pero te libra de CL, incluso obviar la fase de la luna, en este caso el día 29/7/2020 estaba al 70%.

This is the 3rd Target I processed from Data collected over five nights in late October 2025.

This is SH2-171 - The Teddy bear Nebula, and is the result of 33.5 hours of narrowband integration taken with my Astro-Physics 130MM ET f/8.35 system. The camera was an ASI2600MM-Pro, and the mount was one of my iOptron CEM 60s and was mounted on the NW Pier in my Whispering Skies Observatory.

This object is located 3,000 light-years away in the constellation of Cepheus.

I chose this target after reviewing the Sharpless Catalog. I was not familiar with SH2-171, and I was eager to bag a new nebula. However, when processing the data, I saw a spider web knot of dark dust, and that looked very familiar! In fact, I had seen in my image of NGC 7822 -The Central Portion of the Question Mark Nebula - taken one year ago this month!

So, not a new object at all - rather it is a small portion of a much larger and well-known nebula!

I need to research my targets more thoroughly!

My goal here was to maximize the detail in the bright pillars that can be seen towards the bottom and along the left side of the image. The long exposure time meant that noise was much easier to control, and I was able to do that.

This is one of those images where it pays to zoom in and examine the detail closely.

I took some time to collect some additional data on the galaxies Messier 81 and Messier 82 (M81 and M82) in the constellation Ursa Major on the evening of February 28, 2016. I used my wide-field setup which includes my Canon 6D and Canon 400mm lens mounted on an iOptron ZEQ25 mount. I collected 28-minutes of data using 60-second sub frames at ISO 3200. I also took the time to clip and process some of the background galaxies in my large 3 x 5 degree image, you can view them on my blog at: www.leisurelyscientist.com/?p=1592
