A spiral galaxy in the constellation Camelopardalis.
It goes by the nickname of the Hidden galaxy as it's a very difficult target for visual and for photography. This is due to it lying pretty much in the same line of sight as the Milky Way and all it's bright stars and dust lanes. Except IC342 which is about 11 million light years further on.

The time is now! I've heard the requests and for my latest calendar, it is exclusively astrophotography as shot through my telescope/camera setup. I'll unveil all 12 months in the coming days, but for today, I'll open up preorders and share with you a brand new photo that made the cut. More on this photo after the calendar details:
If you want to preorder a 2022 calendar, please fill out this form forms.gle/cNdv9go1NcBQp4tC8 . The calendars will be $18 for preorders and then $20 after November 1. The price includes shipping to anywhere in the US/Canada. The calendars are individually wrapped and all photos are ones that I have shot with my telescope/camera setup of amazing celestial views. I'll be sharing some more of exactly what you can expect next week.
As for this new image... you are looking at NGC 7380, the Wizard Nebula! I first shot this about a year ago when I was still figuring out a lot with capturing/processing narrowband astrophotography, and I just re-shot it a few nights ago and gave it a full new re-process. The final result is a bit more true to how the colors actually appear to the naked eye, as far as the emissions of the various gases involved. The image came from a little over 5 hours of narrowband exposures (105 minutes in Hydrogen-Alpha, Sulfur-ii, and Oxygen-iii separately) in the same night. The individual exposures were 5 minutes long and they were stacked in DeepSkyStacker before being combined in PixInsight.
I think I stopped the aperture down a bit too much on this one, causing the diffraction spikes around the Pleiades's brightest stars. Next time, I'll try f/5.6 or f/6.3.
Taken with a Sigma AF 70-300mm f/4-5.6 APO DG at 133mm and f/8, Canon T3i DSLR, and Celestron Advanced VX mount. Consists of 34 light and 30 dark frames, each a 90-second exposure at ISO 1600, and 21 flat frames. Captured with BackyardEOS, stacked in DeepSkyStacker, and processed in Photoshop.
More commonly known as The Dumbell Nebula. Sometimes as the Apple core or egg timer as well.
M27 is a planetary nebula over 1,200 light years away in the constellation of Vulpecula. Discovered by Charles Messier in 1764 it's thought to be the first planetary nebula discovered.
They were given the title planetary nebulae by William Herschel, who thought that these kind of objects looked small and round like a planet.

While I'm waiting for a new 12mm f2.0 lens, I thought I'd test my new Fuji X-M1 with the kit zoom under the light polluted skies of suburban Melbourne at ISO 6400. Then I pushed and played as much as I dared.
It's not realistic, but it is remarkable what a digital camera and software can do these days.
A photo of our galaxy, the Milky Way, taken just outside our chalet at Crystal Springs Mountain Lodge in Mpumalanga, South Africa. It's amazing what a dark, clear sky can show (along with a little work on the computer). This is 10 photos that I took (each 30 seconds exposure time), stacked together (using Deep Sky Stacker), and then edited a bit in GIMP. My first real Milky Way shot!
If anyone is curious about how I went about getting this shot, I wrote a "how-to" here: digital-photography-school.com/forum/how-i-took/197256-mi...
there the stars are born from the Cocoons.
Covering the large portion of the Milky Way, which is the disk subsystem of our Galaxy, constellation Cygnus houses a lot of gaseous and dusty entities, both bright and dark. This image features among others the tiny bright Cocoon nebula (IC 5146/ Caldwell 19) which is a star formation region and much more prominent dark filament of Barnard 128 (the Snake nebula).
2048 size is quite viewable :)
Aquisition time: 10-11.08.2013 between 23:45 and 01:30 MSK (UTC+4)
Equipment:
Canon EF-S 60mm f/2.8 macro USM lens and Baader Planetarium 2" UHC filter mounted in front of the lens via step-down ring attached to Canon EOS 60D running Magic Lantern 2.3 firmware override riding on Vixen Polarie tracking platform over photo-tripod (alltogether codenamed "Anywhere Is, SWANS configuration").
Aperture 21,4 mm
Focal length 60 mm
Tv = 60 seconds
Av = f/2.8
ISO 4000
Exposures: 58 (plus 27 dark frames and 10 offset frames plus 2 fake flat-field frames).
Processing: Contrast was set to "linear" for all images in Canon DPP and 16-bit outputs were fed to DSS and stacked in Maximum Enthropy mode.
16-bit stacking result was processed in Photoshop with AutoContrast and Levels (namely gamma was set to 3,5) and Curves (skewed sigmoid curve was applied).
Note: I had to crop away some portion at the bottom of the image. The stars were really ugly there.
Comet ATLAS C/2019 Y4, discovered in December 2019, has been quickly increasing in brightness over the last few months, and many of us hope that trend will continue; past projections put it as reaching naked-eye brightness this April or May. However, it's brightness has recently plateaued around magnitude +8. That and an elongated nucleus suggest that it might be disintegrating.
It was likely about magnitude +8 when I photographed it last night, April 9th, near Star 42 Camelopardalis. I'm not sure what the faint nebulosity is to the lower left of the comet: either Dark Nebula HSVMT 25, integrated flux nebula (IFN), or it's simply an artifact. Galaxy NGC 2366 is also apparent in the upper right corner.

Did this the same session as The Ring Nebula. Two images in one session - whatever next? :)
M103 aka NGC 581 is one of the most distant open clusters known, with distances of 8,000 to 9,500 light years from Earth and ranging about 15 light years apart. The cluster is about 25 million years old. Thus spake Wiki.
To me, it's number 27 :)
Taken with a TMB92L, Canon T3i DSLR, and Celestron CG-4 mount. Consists of 34 light and 20 dark frames, each a 45-second exposure at ISO 800, stacked in DeepSkyStacker and processed in Photoshop.
This was inevitable - got to leave it alone now.
Little less brutal, and easier on the blue. Also, I used lens correction in the previous version to compensate for the lack of flattener. That distorts the entire image though, and made the galaxy a little wide of girth! Better in this version I think (if you don't look at the corners) :)

The 'W' of Cassiopeia has always been one of my favorite constellations - maybe because I could always spot it as a kid.
This extent contains the middle three stars of the 'W' - Ruchbah (blue, bottom), Navi (blue, upper left), and Shedar (yellow, upper right). The center star of the 'W', Navi, illuminates the Gamma Cassiopeiae Nebulae (IC 59 and IC 63) a combination of red emission and blue reflection nebulae. The red/pink emission nebula below Shedar is the Pacman Nebula (IC 11 or NGC 281). And to the right of Ruchbah is the Owl or E.T. Cluster (NGC 457); the owl or E.T. is upside down here.
Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 35 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with Astro Pixel Processor and GIMP, taken on Oct. 23, 2019 under Bortle 3/4 skies and thin cloud cover.
Thin cloud cover was present most of the time that I imaged and acted as a diffusion filter for the larger stars. I kind of like this effect that emphasizes big stars, especially for this extent where the nebulae are fairly small for a focal length of 135mm, although I'd always prefer clear skies to a natural diffusion filter. Even though my tracking was spot-on (good balance, polar alignment, and a charged SkyTracker), I wasn't able to use about half of my subs because of clouds.
First light with my first ever dedicated astronomy camera. It was a trial and error evening. After a lot of hair pulling and youtube watching, I managed to get most of the equipment talking to each other. So I decided to try it out on an easy target, Messier 82 the Cigar galaxy. I won't bore you with M82 facts . . . this time. If you do want to know, I did post a picture of M82 not long ago taken with my DSLR. If you flick back through some of my recent pictures you'll find some M82 facts there.
And now for the really boring bit, equipment used:
Skywatcher Quattro 8" Newtonian Reflector steel tube with the f4 aplanatic coma corrector, Skywatcher EQ6 R pro mount, Altair Starwave 50mm guide scope, ZWO asi120mm guide camera mini, ZWO asi533mc pro cooled to -10c, ZWO asiair plus.

Clear sky, no moon, new camera, and news of a comet in Taurus -- who cares if it's a little cold out there....
Posted to Slider's Sunday, even though the post-processing is relatively mild by that group's standards. In particular, let me emphasize that Lovejoy and the Pleiades really did share this little section of the sky. But posted to SS because it used a new (to me) color processing strategy.
Averaged the multiple (28) images in DeepSkyStacker, and imported the result into the Gimp, along with -- and this was the innovation -- an extra copy of the last exposure as a new layer. I roughly white-balanced out the skyglow in the new layer, smoothed it, bumped up the contrast (which has the effect of increasing saturation), and made this the "color" layer to emphasize the actual green and blue colors of the comet and stars.
This is the galaxy designated NGC 5961 located in the constellation Corona Borealis. Inside the galaxy is the supernova 2025ngs that I imaged on July 4, 2025. My magnitude estimate based on 60 minutes of collected data is V16.1.

The Exif data is wrong because this lens doesn't communicate with the camera.
IC 2177 is a region of nebulosity that lies along the border between the constellations Monoceros and Canis Major. The region is often referred to as the Seagull Nebula, and includes a larger nebulous region as well and open clusters NGC 2335 and NGC 2343 and a small reflection nebula named NGC 2327 (in the wing of the Seagull). The open cluster Messier 50 (M50 or NGC 2323) can be seen in the upper left corner.

Fujifilm X-T10, Samyang 135mm f/2.0 @ f2.0, ISO 1600, 40 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing in GIMP, taken July 31 under Bortle 3/4 skies. Conditions seemed about perfect, Sadr was nearly directly overhead, and my focus was dead-on, making processing simple.
Notable nebulae contained in this extent are the Gamma Cygni Nebula around Sadr and the Crescent Nebula near the center.
Taken on my third consecutive night of astrophotography - I'm not going out tonight despite the likely clear skies - I need a break.
Aug. 2 update: A re-edit, this time without a luminance layer - makes the reds less pink.
Having just ordered an Olll filter, this will eventually be my first bi-colour image with Ha and Olll, hopefully. This is about half of the Ha, just 6 x 1200 seconds @ iso1600 with the cooled mono 450D - I'll have to add some more as this is quite noisy.
My mount has been serviced and now appears to be doing its thing as it should. I'll now wait for the next disaster to befall me, as is the nature of this stuff :)
I managed to add 3 hours to my previous version of this on Saturday night, but that has little to do with the above result. This is my first attempt at collaboration with my good friend Dave Williams (whom I have never met, as he lives in the frozen northern wastelands known as Manchester). Dave works in NB, and provided Ha, which I added as a luminance layer (after trying a few other techniques without success), and this is the result. Now I'm fully aware that what you can see above is predominantly luminance, with a bit of RGB thrown in to provide character, so Dave very much deserves most of the credit for this image. However, as he's not on Flickr, I'm happy to accept it :)
This is also my first attempt at combining Ha with RGB (albeit as luminance), and It makes my previous version look a bit sick :)
