Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 50 x 90 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with Astro Pixel Processor and GIMP, taken Sept. 26, 2019 under Bortle 3/4 skies.
This extent contains three frequently imaged nebulae: the Dark Shark Nebula (LDN 1235, center), the dark nebula LDN 1251 (lower left), and the Wolf's Cave nebula, which includes VdB 152, a reflection nebula and LDN 1217, a dark nebula. Other visible objects include the dark nebula LDN 1221 (lower right of VdB 152) and Dengel-Hartl 5, a blue and red planetary nebula (below VdB 152).
I've always loved this extent, which was high on my list of targets for the Samyang 135. I wasn't too happy with my first attempt, but am very happy with this result. Shooting raw, imaging when it was as high as possible, using the "remove light pollution' tool of Astro Pixel Processor, and some more experience processing made the difference.
Messier 88 (also known as M88 or NGC 4501) is a spiral galaxy about 50 to 60 million light-years away from Earth in the constellation Coma Berenices. M88 is one of the fifteen Messier objects that belong to the nearby Virgo Cluster of galaxies. It is galaxy number 1401 in the Virgo Cluster Catalogue (VCC) of 2096 galaxies that are candidate members of the cluster (Wikipedia).

Second of two shtos from this night. This night was unfortunately slightly less transparent than the other night I was out (at least in this part of the sky), but still had ok seeing. At 340 mm, I was only able to manage 60 second exposures with reasonable reliability given the tracking accuracy I was dealing with. 19 of the 30 exposures I took proved usable, and I more or less got the shot I wanted out of it, given the alotted time. Nikon Z6III settings: 340 mm, f/5.0, 60 s, ISO 3200. Stacked with DeepSkyStacker.
I love the juxtaposition of the dark nebulosity in Taurus with the bright Pleiades. Once I figured out mosaics, I knew this would be my second after Orion.
This is a mosaic of 5 different panels taken on two nights, Oct. 2, 2019 and November 20, 2020, 188 x 1 minutes of imagery. 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 used the same process as that of my previous mosaic of Orion: 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 to 70% of the original mosaic.
Located in the constellation Cepheus and probably better known as the Wizard Nebula. I have to say, from the perspective we see it from 7,000 light years away here on Earth, it does look like a wizard wearing a pointy hat in a robe with baggy sleeves.
The NGC number 7380 is actually for the young 5 million year old open star cluster that has formed within the nebula.
Do you see the wizard in the image?

The pinwheel is a face on spiral galaxy found in the constellation of Ursa major, the great bear. Which is a circumpolar constellation, meaning that it never sets below the horizon in the Northern hemisphere.
21 million light years away and some 170,000 light years in diameter, the galaxy is estimated to contain upwards of one trillion stars. It was first observed by Pierre Méchain on the 21st of March 1781.
M101 is just about visible through a pair of 10x50 binoculars under a dark sky with the right conditions. Though a telescope of 6" and above would be preferable.

Messier 3 (also known as M3 or NGC 5272) is a globular cluster found in the northern constellation of Canes Venatici. M3 is one of the three brightest globular clusters in the Northern hemisphere (along with M13 and M5).
Tech Specs: This image is composed of 8 x 60 second images at ISO 3,200 with 4 x 60 second darks and 4 x 1/4000 second bias frames using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Guided using a Canon 400mm lens and ZWO ASI290MC camera. Imaging was done on April 14, 2017 from Weatherly, Pennsylvania.
First attempt at hydrogen-alpha 12nm narrowband using an DIY astro-modified second-hand Canon 450D and the superb nifty-fifty lens for astro. Had to remove a number of frames due to northern lights flooding the light frames, and struggled to stack and stretch the files in PixInsight and DeepSkyStacker, producing a lot of noise and banding patterns. Sequator let through some hot pixels, but can live with that as the background noise was a lot lower than wiht PI and DSS. Final edit in Adobe Lightroom. The light frames were a sea of red though, so I wonder if longer exposures at lower ISO400 may be better? Read somewhere that ISO400 is the sweet spot for dynamic range versus gain on the 450D.

M106 can be found in the constellation Canes Venatici. Binoculars will show it as a smudge in a dark enough sky. However, an 8 inch telescope will start to reveal some detail. It's a wonder we see it at all, given that it's almost 24 million light years away from us. Maybe it's the light of the estimated 400 billion stars it holds within that helps us to see it.

An image of the Dumbbell Nebula (M27) taken with a ZWO183MC Pro camera on a Celestron 130mm f/5 reflecting telescope. 60 thirty second light images and 60 dark images were combined using DeepSkyStacker and processed in Adobe Lightroom to create the picture.
A portion of the Milky Way in these summer days with the Dark Horse Nebula.
This nebula is one of the largest object of the deep sky. It is made up of many "small" dark nebulae mainly composed by interstellar gas clouds so dense to block light passing through.
Thanks to this simple mechanism we can detect the presence of such objects: by observing their silhouettes.
More extra info: the horse's back paw is usually called Pipe Nebula. And yet, in the belly of the horse lies a "small" (but fortunately visible in this photo) dark nebula with an "S" shape called Snake Nebula. Can you see them?

🔭 ...OR JOIN THE BLUE JOURNEY PROJECT:
Referred to as Bode's Nebula, it is however, a spiral galaxy located close to the Big Dipper or Plough asterism in Ursa Major. It has a close companion galaxy M82 the Cigar galaxy, so close together, they are often imaged as a pair.
Lying about 12 million light years from Earth and about 90,000 light years across. Binoculars will pick up M81 as a faint fuzzy patch of light under reasonable sky conditions.
First discovered by a German astronomer by the name of Johann Elert Bode in 1774, hence Bode's Nebula. At the time no one had any clue it was a whole other galaxy.

NGC 7635 The Bubble Nebula.
The open star cluster to the upper left is M52 the Salt & Pepper cluster.
Discovered by William Herschel in 1787, the Bubble Nebula lies within the boundaries of the constellation of Cassiopeia at a distance of 7,100 light years away. The bubble itself spans some 7 light years across. For perspective the nearest star to our Sun is only 4 light years.
The bubble is expanding at a phenomenal rate. There is a super massive star that is creating the 'stellar winds' causing the bubble to expand. It can be seen in the image to the upper centre within the bubble. These 'stellar winds' are moving at upwards of 4 million miles per hour!
The star is estimated at 4 million years old, so it's just a baby really. Though because it's so massive, it will burn through it's fuel much more quickly. NASA estimate just 10 - 20 million years before it goes BANG as a supernova.
The open star cluster M52, contains over 100 stars and is a little closer to us than the Bubble Nebula. Discovered by Charles Messier in 1774 it's distance is estimated to be somewhere around 4000-5000 light years away.

Stacked (comet center only), plus a few brush adjustments...came out much better than I initially expected (seeing conditions were pretty poor). Probably would have been better if I did it at 135 mm on Tuesday night, but it's something! DeepSkyStacker: 200 mm, f/2.8, 12800 ISO, 1.6 sec x 48 frames.
All part of the Veil Nebula in Cygnus - aka the Cygnus Loop - this is the Western Veil and Pickering's Triangle (the triangular looking bit). It's the remnants of a supernova in the distant past.
There's lots of it missing, but I doubt I'll be able to pick up much more with a DSLR and my skies. Had to throw every weapon in my processing armoury at it to get this much! Having said that, I may have another crack next year :)
This is 38 x 5 minute subs (just over three hours) with the usual kit.
Another quick test of my new Skywatcher Star Adventurer Mini tracking mount, this time shooting the Milky Way. It was cold and very windy, my polar alignment was not very accurate and I didn't frame the shot as well as I could have, but for a test shot I'm fairly happy with the result.
This is 5 x 2 minute exposures with my 6D and the old 35mm f/2 lens at f/3.5 and 1600 iso. Stacked using DeepSkyStacker and processed with LR5.
At the risk of boring you guys rigid, I had to post this as the difference is quite pronounced. This is the same image as my previous post (different orientation, to avoid boring repetition). I was faffing around with this (as you do) in Match Colour in PS and hit the Neutralize check box, which removes any difficult colour casts. I didn't even realise the image had a colour cast until this came out. An improvement in colour I think :)
This was a tricky one for me. This is a stack of 12 x 3 minute exposures, tracked on an iOptron Sky Tracker. I originally tried stacking this both in DeepSkyStacker and Photoshop, but the results were blurry and not very good. That was because there was a lot of thin, wispy cloud blowing through as I was shooting this.
I tried stacking this one again tonight removing all the worse frames where clouds had obstructing too much of the frame. What started as 90 minutes worth of exposure was thereby whittled down to 36 mins. There were still clouds in the other pics, as can be witnessed by the halos around the brighter stars, but overall the amount of cloud was manageable so that median stacking would eliminate most of their effect. Then, rather than my usual method of processing Milky Way images, I used a workflow I'd normally use for deep sky objects. Due to the level of detail captured.
And this is the end result. It's not as perfect as I'd like it to be, but overall I'm pretty happy with the final result.

This is a spiral galaxy that sits approximately 2.5 million light-years away from us. It has a diameter that spans over 220,000 light years form tip to tip, and carries somewhere around 1 trillion stars.
I created this image from 30 tracked exposures, each running at 30 seconds, using ISO 1600. I also used darks, flats and bias frames. Final editing done in photoshop to get this image right, especially because I was dealing with light pollution in the city. Taken in my backyard on a clear night with no moon, in the city.

An unguided image of the Sombrero Galaxy (M104) in Virgo taken with a ZWOASI183MC Pro camera on an Explore Scientific 102ED refracting telescope. 30 45 second images were used to make the image with Deepskystacker, Gimp, and Lightroom.
Also known as The Crescent Nebula.
When you see some of the amazing widefield views of this nebula shot with triplet & quad refractors and narrowband filters it almost looks like a brain in space!
Found in the constellation of Cygnus the Swan, the Crescent Nebula is approx 25 light years across.
Around some of the edges you can just make out some faint bluish hue, these are oxygen atoms, these look really awesome in good narrowband images. One day I may have the money to go down that path.
Data gathered at The Astronomy Centre, Todmorden, UK.

Target:SH2-101 Tulip Nebula, emission nebula, Cygnus, 6000 light years away.
Location:1 & 3 June 2022, St Helens, UK, Bortle 7. 17% Moon, windy.
Acquisition:38x 240s Ha, 36x 240s (OIII) calibrated with Darks, DarkFlats, and Flats. Total Integration 4.9 hours.
Equipment:Skywatcher 200P Newtonian, EQ6Rpro. ZWO EFW. Altair H183Mpro. Baader MPCCMkIII coma corrector, 6.5nm filters.
Guiding:Skywatcher Evoguide 50ED. Altair GPCAMAR0130M.
Software:NINA, PHD2, EQMOD.
Processing:DeepSkyStacker, Siril, Affinity Photo, StarXTerminator, Topaz DeNoiseAI.
Notes:Imaged over 2 nights and processed as HOO. The first night was Moonless, calm but very humid with high passing cloud whilst the second had 17% moon and was very windy resulting in a number of lost subs. No true darkness so imaged during nautical twilight with the (OIII) sandwiched between shorter Ha runs so the (OIII) was taken during the darkest part of the session.

Lots of processing going on here, including stacking of 10 lights with 5 darks in DeepSkyStacker, with further adjustments in Lightroom. Each exposure 20s / F2.8 / ISO1600
Sadly I forgot to switch off SteadyShot and so some blurring of the foreground occurs!

The 'Boneyard' - Kiama, on a very windy night ... Pentax K1 w HD15-30 stacked and blended image ... this one was a bit of a challenge .. no moon and very little starlight .. pretty happy with the result :-)
The sky-gods surprised me last night with 3 semi-clear hours. I quickly set up the RedCat 51 and Canon EOS Ra for some wide-field deep-sky images in Auriga.
Here is 50 x 3-minutes at ISO 1600 on the Flaming Star Nebula and Tadpole Nebula at a true 250mm focal length.
You can also see the "Spider and the Fly" in there.
This was a fantastic test of the Ha sensitivity of the Ra using a dual bandpass filter (Optolong L-eNhance).

Oh my... I really love this one. The Flame Nebula (NGC 2024) is the central orange component in the image and the bright star is Alnitak, the leftmost star in Orion's belt. And the craziest part (to me) is that this is just an RGB image... this is what's actually there with a normal exposure, colors and all! I used about 3 hours of Red, Green, and Blue data... from individual 3-minute exposures stacked in DeepSkyStacker and combined in PixInsight.
I shot this on Monday morning for the hours after midnight when Orion was higher in the sky and above the neighbor's trees. In addition to the Flame Nebula, the red trailing off at the bottom is part of the Horsehead Nebula and there are a few small other nebulae that you can see around the frame. We're wrapping up a tiny sequence of clearer nights right now, so I hope to have some more brand new telescope-shots to share with you soon!
