This is a pair of interacting galaxies in the constellation Pegasus designated as NGC 7253A and NGC 7253B. Halton Arp divided his “Atlas of Peculiar Galaxies” into groups based on purely morphological criteria. The pair of galaxies here received the designation Arp 278 as a pair of interacting galaxies.

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.

The core of the Milky Way skirts the horizon for us folks in the North. However, that doesn't discourage us from the challenge of pulling fascinating details out of the muck!

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 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.

Thank all for your visit and awards.

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.

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.

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?

This diffuse emission nebula also designated SH2-86 in the Sharpless catalogue is the home of the young open star cluster NGC 6823, visible in the centre of the image.

The nebula is estimated to be just under 6,000 light years from us and can be found in the constellation Vulpecula.

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.

From SpaceTelescope.org, “NGC 7006 resides in the outskirts of the Milky Way. It is about 135,000 light-years away, five times the distance between the Sun and the center of the galaxy, and it is part of the galactic halo. This roughly spherical region of the Milky Way is made up of dark matter, gas and sparsely distributed stellar clusters.”

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.

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.

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.

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.

Technical note: I used ISO 1600 and took 4 minutes of light frames and 12 minutes of dark frames. The low amount of digital noise with a 3:1 dark:light ratio is pretty worth the effort.

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).

M33 Triangulum galaxy

I've always struggled with this target. I use an old Canon 1100D unmodified camera and really struggle to get the fainter parts of the spiral arms.

This image was done with a Skywatcher 8" quattro with f4 aplanatic coma corrector on a HEQ5 pro mount.

Guiding was with an Altair 50mm guide scope and an Altair GPcam1 AR0130c

I used an unmodded Canon 1100D with an Astronomik clip in ccd filter and a Neewer intervalometer.

Software used was DeepSkyStacker, StarTools & Gimp.

Messier 36 (M36 or NGC 1960) lies at a distance of about 4,100 light years away from Earth in the constellation Auriga and is about 14 light years across. There are at least sixty members in the cluster. The cluster is very similar to the Pleiades cluster (M45), and if it were the same distance from Earth it would be of similar brightness.

Distance: 4,340 light year.

Radius: 7 light year

Stacked in DeepSkyStacker and post-processing in PixInsight.

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.
