'Ave anuvver one :)
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.
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.
20, 3 minute exposures bin 1 gain 0, stacked with darks, flats and bias.
DeepSkyStacker, StarTools and Affinity Photo used for processing.
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.

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.

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.

[edit: reprocessed]
Ho usato solo lo spianatore con il 102 a 700mm, sono molto contento del campo ai bordi :) ma si sono generati due strani flare che erano già comparsi con la foto delle Pleiadi di settembre, chiaramente non ho la benchè minima idea di cosa la generi, forse il filtro skyglow, nelle due foto ho usato due spianatori differenti..

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.
Antares only rises to 23 degrees altitude max and the best imaging window is 3 hours per night in the beginning of june. And of course without moonlight. This year my only shot was a 3 hr window on june 7. This is a 2 panel mosaic made with the Esprit 100 f5.5 APO and Canon 6Da and Optolong L filter. (total 53x180 sec iso 1600 I plan to add more panels over the next few years. Processed with DeepSkyStacker (2 stacks) and Pixinsight (DBE, Histogram, Staralignment, Gradientmegemosaic, curves)

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) :)

A closer view of the comet between the trees at the bottom of our garden, just before midnight on 17/18 July. This is a manual stack of eight images in Photoshop - I could not get DeepSkyStacker to work on this sequence.
I think my source photos were soft and off-focus and this hasn't helped in the final image stack, where I used the comet head as the reference point.

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.
I combined a stack of 10 with DeepSkyStacker to deal with the noise, and I had a heck of a time doing it, too! :) Maybe because I accidentally shot in jpeg...

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.
Last night I added some time to a session I did in February for a total of just over four hours of 3 minute subs. Struggled to beat the first version I did of this 2 years ago, and that was only 28 minutes for heavens sake! Got there in the end though :)
That star was gagging for some spikes :)

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.

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 :)

The Andromeda Galaxy or M31 as captured in a stack of fifty-four images that were exposed for 25 seconds each using a hand-driven, barn-door type tracking mount (two boards, a hinge, and a screw you turn by hand). This photo also shows Andromeda's two satellite galaxies, M32 and M110 (see image notes for the locations, M110 is the small elliptical galaxy slightly below center).
This photo was taken using a 50mm Nikkor AF-D lens on a Nikon D5100 DSLR and it is best viewed in the Flickr light box (press the "L" key to toggle the light box and optionally click on the "View all sizes" menu item to see the image at its largest size).
With the aid of the Cartes du Ciel star charting software (highly recommended free download) and with an examination of the area surrounding M110 I've determined that the limiting magnitude in this photo is around 14.5 (stars nearing the 14th magnitude are clearly shown, fainter than that are more difficult). There is also a definite halo around the small satellite galaxy M32, a detail which was not that apparent in my earlier post.
The brightest star in this photo (above center) is Nu Andromeda at magnitude 4.5 and it is located just over one degree from the center of the Andromeda Galaxy. One degree is just about twice the apparent size of the full moon, so you can see that the Andromeda Galaxy (as recorded in this photo) is several times the size of the full moon.
Captured on September 28 and 29 between 11:34PM and 12:28AM PDT with a Nikon D5100 DSLR (ISO 4000, 25 second exposure x 54) and a 50mm AF-D Nikkor lens set to aperture f/2.8. Image stack created with DeepSkyStacker using 54 image frames combined with 27 dark frames (no flats or bias).

Finally was successful in this shooting session after two years of trials and errors with countless fails of guiding and imaging. I was able to acquire a little over 1h10min for this image.
This was the very first DSO image I've seen when I was a kid on NASA's APOD, it amazed me on the first sight.

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.

The Triangulum Galaxy is a spiral galaxy approximately 3 million light years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598, and s the third-largest member of the Local Group of galaxies, which includes the Milky Way, the Andromeda Galaxy and about 44 other smaller galaxies.
With a diameter of about 50,000 light years, the Triangulum galaxy is the third largest member of the Local Group of galaxies. It may be a gravitationally bound companion of the Andromeda Galaxy Triangulum may be home to 40 billion stars, compared to 400 billion for the Milky Way, and 1 trillion (1000 billion) stars for Andromeda. from wiki

Three clear nights on the bounce - whatever next?! :)
Took advantage of the weather to give this a really good crack, something I've been waiting to do since the arrival of the ED80. This is full frame, so the focal length is ideal. As near as dammit 8 hours total exposure, made up of various sub lengths and iso settings. The variation in iso seems to improve the overall noise in the final tif, so I was able to stretch this a little further (some would say too far!). Not sure if it's a little too contrasty - all a matter of personal taste I suppose. Overall, I'm very pleased with this :)
