Globular Cluster Messier 62 (M62 or NGC 6266) is a cluster that can be found in the constellation of Ophiuchus. This cluster was photographed in July 16, 2015 nd the final image is a stack of 18 thirty second exposures at ISO 3200 using a Canon 6D at prime focus of a Celestron 6" telescope. The imaging system was mounted on an iOptron ZEQ25 equatorial mount. M62 lies at a distance of about 22,500 light-years. Software used to create this image include DeepSkyStacker (for stacking the individual frames), ImagePlus (for initial stretching and post processing), and Corel Paintshop Pro X5 for the final image adjustments.
The bright star just off-center is Polaris, which is surrounded by Integrated Flux Nebulae (IFN) named the Polaris Flare, discovered in 1984 by Heiles (Panopoulou et al. 2015: doi.org/10.1093/mnras/stv1301). Yildun, the brightest star in the lower right-hand corner, is the next star in the 'handle' of the Little Dipper.
Acquisition details: Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 78 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with Astro Pixel Processor and GIMP, taken on Apr. 11, 2020 under Bortle 2/3 skies.
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) away from Earth in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781 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 August 24, 2011, a Type Ia supernova, SN 2011fe, was discovered in M101.

Thank all for your visit and awards.
The California Nebula at 135mm 📷
Just 30 x 90-seconds at ISO 800
You can't beat capturing a full-color image in an hour (set-up time included!)
I love the FOV the Rokinon 135mm provides (thank you again to everyone that recommended it)!
This was a quick setup when the clouds parted for 2 brief hours last week (snowing now). I spent longer processing the image than acquiring it 😆

Also known as IC 434 and Barnard 33.
The horsehead nebula is approximately 1,375 light years away in the constellation of Orion. A very difficult target to find in a telescope, it's possible with a large aperture using specialist filters. A camera that can pick up Ha it's much easier :-)
IC 434 lies on Orions belt close to the flame nebula with the very bright star Alnitak (just visible lower left) separating them.

Messier 100 (also known as NGC 4321 or the Mirror Galaxy) is a grand design intermediate spiral galaxy in the southern part of the mildly northern Coma Berenices. It is one of the brightest and largest galaxies in the Virgo Cluster and is approximately 55 million light-years from our galaxy, its diameter being 107,000 light years. (ref: Wikipedia) The last time I imaged this galaxy was March 2023 when the dwarf planet Ceres was passing between the Earth and Messier 100 spiral arms.

NGC 7331, also known as Caldwell 30, is an unbarred spiral galaxy about 40 million light-years (12 Mpc) away in the constellation Pegasus. It was discovered by William Herschel in 1784. NGC 7331 is the brightest galaxy in the field of a visual grouping known as the NGC 7331 Group of galaxies. The other members of the group are the lenticular or unbarred spirals NGC 7335 and 7336, the barred spiral galaxy NGC 7337 and the elliptical galaxy NGC 7340. These galaxies lie far in the background at distances of approximately 332, 365, 348 and 294 million light years, respectively.

You can see that it was 19 shots to the right of Venus, presumably a satellite shown in stop motion! Shot with an old Sigma 70-210 f2.8 (at the 210 end) which has not been chipped so can only be shot wide open.

I wanted to see how far a smartphone capable of doing long exposures (32 s), manual focus and saving RAW files could take you for acquiring widefield images. No tracking, just a simple (rather flimsy) tripod with a smartphone clamp.
I think it turned out rather well, considering that this was by no means high-end equipment! So if you would like to take Milky Way photos, but don't have expensive astrophotography gear (or not even a DSLR camera), just try what your phone can do!

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. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across.
The Orion Nebula is one of the most scrutinized and photographed objects in the night sky and is among the most intensely studied celestial features. The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust.

This is a pair of interacting galaxies known as NGC 7753 and NGC 7752, collectively known as ARP 86 (as listed in Arp's ATLAS OF PECULIAR GALAXIES). The pair are located in the constellation Pegasus and are about 272 million light years away from Earth. They remind me of a smaller version of the Whirlpool Galaxy, Messier 51.

Another one from Long Beach while the skies held and the Moon was just below the horizon.
Fun fact: M42 is around 1,300 light years away, making it the closest massive star formation to earth. That's probably why it's so damn bright :).
Exposure time was 50 minutes, 25x120s @ ISO800 with the 400/2.8 + 1.4x TCII on a Nikon D7100 for an approximate focal length of 550mm (825mm in 35mm terms).
Post-exposure, I took 58 minutes of dark frames, which were then integrated in DeepSkyStacker and processed in PixInsight and Lightroom 5.

The Milky Way's sibling looked really pretty this morning. Autumnal air made for good observing conditions. Photographed from Huntsville, AL.
I'm actually pleased as I can be with this image. It is the culmination of a lot of trial and error,and some (possibly unreproducible) experimentation with post processing.
The field flattener, better focus and longer exposures at lower ISO yielded a nicer image, by far my best to date.

Never done this one before for some reason, and it's quite bright up there in Orion. And it does look remarkably like a monkey head, it has to be said. This is 25 x 300 sec subs. Looks better in hubble, and I'll do that one day :)
If we get many more clear nights I'm going to run out of targets. Not complaining of course! :)

Still practicing with my new SCT and focuser. I had horrible coma in my first image, but I went a long way towards fixing the collimation with this one. Still needs better collimation though, so that'll be my next step.

The Jellyfish Nebula IC 443 aka Sh2-248 is a supernova remnant hanging up there in Gemini. It's about 5k light years from us.
Having put a post on my fb page looking for an alternative to DSS, DSS got its revenge. It spat out junk every time I stacked this until, in exasperation, I purchased a copy of Nebulosity. DSS then stopped assing about and gave me a reasonable stack. Spooky.
Anyway, this is 28 x 8 minute subs under my light polluted skies, so is a decent result :)

NGC 6946, (also known as the Fireworks Galaxy, Arp 29, and Caldwell 12), is an intermediate spiral galaxy about 18 million light-years away, in the constellations Cepheus and Cygnus. It was discovered by William Herschel on September 9, 1798. NGC 6946 is highly obscured by interstellar matter of the Milky Way galaxy, as it is quite close to the galactic plane. The diameter of the galaxy is approximately 40,000 light-years or just about a third of the size of the Milky Way.

Knife Edge galaxy.
Sometimes referred to as the Silver Needle galaxy. Though this can get confusing as NGC 4244 also carries this nickname. You can find NGC 5907 in the constellation of Draco, as William Herschel did way back in 1788 for the first time.
At a mere 50 million light years distance NGC 5907 is the home of the groundbreaking pulsar NGC 5907 X-1. www.esa.int/Science_Exploration/Space_Science/The_brighte...

This dark nebula resides in the constellation Ophiuchus and resembles the shape of a smoking pipe (pretty sure they named this one in the '60s).
It features a prominent lane of dark dust obscuring the countless stars behind it.
This deep-sky object is visible to the naked eye under pristine, dark sky conditions (use binoculars for the best view)!
I took this photo using my portable astrophotography setup from the southern hemisphere - where it gets much higher in the sky than it does from home!

I already was all too happy to bring out the reflection nebulae in M45 for the first time recently, after a long period with lousy weather. Then good luck struck twice, allowing me to double my exposure time, and also to reduce the walking noise in the stacked image I experienced the first time by some manual DEC dithering fun. Quite some work, but the things you do for pretty pictures... (on top of freezing and lack of sleep of course, heh).
Indeed spending that extra work gave a huge boost to the final image quality, and I also think I hit the spot better with post-processing this time around.
So what you see here are a total of 2.5 hours of exposure with the TAIR 3S (@ f/5,6) over two nights, after discarding some subs that suffered from either tracking errors or gusts of wind (but with overall good success rate).

Not my favourite subject, but not a lot up there at the moment, and we had a couple of clear nights :)
Five sessions between 1-29 April 2013 - total 10 hours 38 minutes. I don't think giving the total exposure is of much help to anyone really, as the result depends on so many factors, not least the quality of your skies (pretty low in my case). But it at least demonstrates how much effort has been expended :)
And the stars are almost round :)
