VdB 14 & 15 (left in the picture) are two very beautiful reflection nebulae, which also contain a few reddish emission components and belong to an even larger dust cloud in the inconspicuous constellation Camelopardalis. VdB 15 is the larger, lower area of the nebula and surrounds the star CE Cam, a variable supergiant. VdB 14, the upper part of the nebula, is located near the star CS Cam, which is also a supergiant. The distance to earth is around 3,000 lightyears.
The open star cluster Stock 23 can be found on the right in the picture and is also a nice object for visual observation. Its distance is estimated at 1,240 lightyears and it is surrounded by several spectacular dark clouds. It is embedded in the large but faint emission nebula SH2-202, which extends over the entire right half of the picture.

The Lagoon Nebula is one of the brightest nebulae in the night sky - bright enough for some people to see with the naked eye as a hazy patch in the sky. Around 5,000 light years from earth, this giant interstellar cloud is a nursery for young stars. These baby stars heat up the nebula gas so much that it emits light - light we can see. We may not see much with our naked eye but with a little help and a little patience, we can see a whole lot more.
Calibrated images of the Lagoon Nebula were provided by iTelescope.net. In addition to providing access to their telescopes, iTelescope.net provides subscribing members with a combination of premium image sets (with the rights to use & post them) and webinars that show how to process them.

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.

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.
This is the wonderful globular cluster M 3 in Canes Venatici. It‘s one of the largest and brightest, and is made up of around 500,000 stars. It is estimated to be 11.4 billion years old and 32,600 light-years away from Earth. I had already photographed this cluster for about 3 hours last year and was able to add another 2.5 hours this time, which made the faint stars in the outer regions of the cluster more visible. Well, M 13 in Hercules is even more spectacular, but I think M 3 is worth to take a closer look at it. Hope you like it!

One of the objects I was able to photograph last night with some unusually clear sky after many cloudy nights, despite it being quite near the horizon. This is one of the more colorful regions of the Milky Way, called the Rho Ophiuchi nebula after the bright star within the blue cloud near the top. The brighter red star near the bottom is the brightest star in the constellation Scorpius called Antares, the Heart of the Scorpion. Much of the region is filled with dust, reflecting the light of nearby stars as well as some gas, mostly hydrogen, glowing because it's energized by the nearby hot stars.

This is an extremely difficult target for me as I live around 16 miles south of the UK's second largest airport London Gatwick, so battling light pollution from Gatwick and trying to bring out the faint dust is a huge challenge, but I like a challenge and I am extremely happy with the final result

Galaxy IC342 can be found in a dusty region, 10 degrees from the Galactic Equator but that dust is not very bright. Almost all IC342 images show just the Galaxy, not the dust in the surrounding region. It was not my intention to image that dust, but when i made a luminance stack with all the 271 (300 second) subs i had, there it was....
The inverted image is annotated and i added surface brightness data for a couple of faint Galaxies. KK35 or PGC166077 with a surface brightness of 26.85 mag/arcsec² was thought to be a Dwarf Galaxy but it most likely is an outher region of IC342.

I managed to catch a nova last night! That's an unusual astronomical event in which a star brightens tremendously in a short time. This one, known as Nova Cas 2021 was discovered in the constellation Cassiopeia just a few days ago and is now bright enough to see in binoculars and photograph with modest equipment. It also shares the view with some other interesting objects: an open cluster of stars, Messier 52 (M52) and a nice star-forming nebula, NGC 7635, known as the Bubble Nebula for the interstellar cavity being blown by a bright, young star.
By studying spectra (the distribution of the light across colors/wavelengths) and the light curve (the change in brightness over time), astrophysicists have determined that Nova Cas is a "classical nova" in which one of the stars in a close binary system transfers some of its mass to its white dwarf star companion, which eventually results in a tremendous nuclear explosion that we can see across the galaxy. Here's an article from Astronomy Now with more information: astronomynow.com/.../new-nova-in-cassiopeia.../.

Some astronomy images leave me wondering if I can actually find the object (named in the title) in the picture. Like finding objects in clouds in our daytime skies, objects in astronomy pictures are sometimes easy to find and sometimes not. Admittedly, my first view of images from this scene gave me a similar feeling - I guessed because of the thick field of stars. So in processing, I removed the stars and BAM! There were the dragons and the egg they were fighting over.
Calibrated images of the Fighting Dragons of Ara and the Dragon's Egg Nebula were provided by iTelescope.net. In addition to providing access to their telescopes, iTelescope.net provides subscribing members with a combination of premium image sets (with the rights to use & post them) and webinars that show how to process them. Itelescope.net captured the images using their T71 telescope based in the Rio Hurtado Valley, Chile. This was especially helpful because the Dragons of Ara are visible in the Southern Hemisphere where I live in Colorado. After capturing, I handled the post-processing side with Astro Pixel Processor, Photoshop, Star Xterminator, Topaz Sharpen and DeNoise AI.
