DESCRIPTION: Beautiful blue reflection nebula with dark dast around in constellation Cepheus. The nebula which shines at magnitude +6.8, is illuminated by a magnitude +7.4 star SAO 19158. Apparent dimension 18’ x 18’ is on the limit of possibility for my Nikkor 500 mm / f 5,6 PF lens. Exposure is little bit tricky. The core is relatively bright and must be correctly exposed (unfortunately not my case). All constructive comments are welcome. You can be critical. I would very much appreciate your advice and tips.

Open star cluster taken by Nikon Z7 + 70-200/2,8 @ 200. 113 light frames by iOptron SkyGuider Pro tracker. Exp. 30 s, ISO 3200, f 2,8. No Darks, no Bias. Stacked in AstroPixelProcessor, processed in Adobe PS, LR. Cropped 4x. M45 has apparent dimension approx. 120 arcmins.

This is my most recent image of M13. It is a globular cluster in the Hercules constellation. It is about 20,000 lightyears away and contains somewhere around 400,000 stars, although I have heard estimates of up to 500,000 stars. It is one of my favorite objects to look at through an eyepiece and it is a relatively easy deep space object to photograph. Even though it is one of the brighter objects in the sky to image it can always can be better with time and patience.

I used a Sony A7RIII camera mounted on an Istar 140mm refractor. I picked the best 22 frames that were 60 second exposures stacked them and post processed them in Astropixelprocessor.

This region of the sky, in the constellation Monoceros, contains many different types of objects including Reflection nebulae (NGC2170), Hydrogen Alpha Emission nebulae (LBN999) and lots of surrounding molecular dust clouds. It is low in the sky from my latitude so more difficult to capture clean data and I also battled with intermittent clouds and a large number of satellite trails.

This one was a pain. I totaled 9 hours of exposure and the final integration was a bit over 6 hours. Processing time was way more than that! I struggled to get a compromise of the beautiful blues and the red nebulosity in this galaxy. I'll try again later in the year.

Comet C/2017 K2 (PanSTARRS), currently the brightest comet in the sky. This image is from the dark and clear morning of June 30th from suburban Bloomington, Ind., with the comet against the rich star background of the constellation Ophiucus. It will be getting a little closer to Earth in the next couple of weeks and so may still be a bit brighter, but will be up against a bright, full Moon, so this may be the best I can do.

It's been so long since I've been out imaging that I was a bit worried I'd forgotten how it all worked! So on a very unsuitable but clear night, under a nearly full Moon, I went out to give everything a shake down and refresh my memory. Whilst about it I took this image of 'The Great Hercules Globular Cluster' or M13. There were horrendous background gradients caused by the Moon but not bad for a 'just testing' image. Taken with my Canon 80D rather than a specialised camera.

About 145 light-years in diameter, M13 is composed of several hundred thousand stars. M13 is 22,200–25,000 light-years away from Earth. Notice too the little smudge of light to the upper left of M13. That's a galaxy lying around 30 million light years from earth. (Light travels 186,000 miles every second!!!)

Last night I was able to get an updated image of the comet C/2022 E3 (ZTF), now known as the Green Comet or Circumpolar Comet (because it rotates around the north pole through the day and never sets below the horizon). It is approaching the Earth and will be closest to us around Feb. 1st before it returns to the distant depths of the Solar System. It's showing some very interesting structures, even from a fairly bright suburban sky.

The second image labels the main structures: nucleus (an icy/rocky body too small to see anything other than a point), coma (the fuzzy stuff around the nucleus), both a dust and ion (gas) tail, and even an antitail in the opposite direction to the other tails. The comet was also passing in front of a very distant galaxy known as NGC 5894, 130 million light-years away.

This is a composite of 113 frames, 60 sec. each (almost 2 hours total) from suburban Bloomington, Ind. It was processed twice: registered on the comet and separately on the stars and combined in Photoshop. (The comet moves across the sky fast enough that there is noticeable motion in a few minutes. Either the comet or the stars would be trailed in a standard composite).

Messier 83 (M83), also known as the Southern Pinwheel Galaxy, is a barred spiral galaxy located in the southern constellation Hydra. M83 lies at a distance of 15.21 million light years from Earth and has an apparent magnitude of 7.54. It has the designation NGC 5236 in the New General Catalogue.

The Southern Pinwheel Galaxy occupies an area of 12.9 by 11.5 arc minutes of apparent sky, which corresponds to a spatial diameter of about 55,000 light years, or roughly half the size of the Milky Way. M83 is one of the nearest and brightest barred spirals in the sky and can be seen in 10×50 binoculars, which only reveal a patch of light with a brighter core.

... is an emission nebula in the constellation Cygnus lies 2,590 light years away, close to Deneb (the tail of the swan and its brightest star). The shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico ( so it is said ;) ).

I finally got the chance for a few nights this month on this wonderful target: A beautiful, if faint, emission nebula between Cepheus and Lacerta and probably my favourite nebula to date - The very small planetary nebula (bottom left) is Abell 79. Abell 79, "The 6 Nebula", is estimated to be at a distance of 5900 to 11,360 lys away. It measures approx 1 arc minute and is magnitude 15. Sh2-132 lies at an estimated distance of about 10,000-12,000 lys and is ca. 40 arc minutes in size. The image also contains the very small planetary nebula G101.5-00.6, which lies to the right of the blue O-III region.

Comet C/2021 A1 (Leonard) continues to brighten. Early this morning (3 December) it danced with the nice globular cluster M3. From suburban Bloomington, Indiana, with no Moonlight but plenty of light pollution.

75 frames, each 90 sec. (nearly 2 hours total exposure), processed in Astro Pixel Processor, once to register on the comet, again to register on the stars, processed in Lightroom and composited in Photoshop.
