I spent Sunday night setting up my scope again, aligning it, and tracking the Triangulum Galaxy. The Triangulum Galaxy lies ~2.7 million light years away from Earth and is part of our local group of galaxies. It lies in the constellation Triangulum, from where it gets its name. Charles Messier cataloged it first in 1764. He published his Catalog of Nebulae and Star Clusters in 1771 and listed it as object number 33, hence the name M33.

My Sony a7RIII and adapted Nikkor 500mm f/4 P AI-S were mounted on an ADM vixen rail and secured to the SkyWatcher EQ6-R mount. I polar aligned my mount using SharpCap Pro. The guide scope/camera was attached to the camera's hot shoe. I used PHD2 to autogude during the imaging session. DeepSkyStacker was used to combine all frames, and then I processed the TIFF file in Photoshop. I stretched the 32-bit file and used Gradient XT on the image. I then made it a 16-bit file and continued to stretch the file in levels, then curves. I used the color sampler tool and levels to do my best to help keep colors accurate. I then used my skillset, including some dodging & burning, and relied on Astronomy Tools Action Set and Topaz Denoise to give the image a polished look. I brought it into Lightroom to do final color corrections and add EXIF data.
Like three years ago, starting the new season with a wonderful and enchanting Hubble's Variable Nebula (NGC 2261)
Previous approach: www.flickr.com/photos/olegbr/8552071862/in/dateposted/
I wanted to personally check whether it still variable ...
It was found that this is so :)
Here animation L-channel 200%: olegbr.astroclub.kiev.ua/files/astrofoto/NGC2261/NGC2261_...
Of course, 3 years - a very large interval for observing the changes in the nebula. Everything is much faster: www.umanitoba.ca/science/astronomy/cbrown/imaging/hvn/ana...
In 2013-2016 animation, I drew attention to the star just above the nebula, which is for 3 years significantly shifted to the right.
To heighten the effect, combined with the current picture image DSS., For about 60 years, the offset is already pretty decent. olegbr.astroclub.kiev.ua/files/astrofoto/NGC2261/NGC2261_...
Here www.astrosurf.com/mcianci/ngc2261.html Italian colleague calculated that the proper motion (proper motion) of the star 0.2" per year. The name is NLTT 16798 and is listed as High Proper Motion Star: simbad.u-strasbg.fr/simbad/sim-id?Ident=NLTT+16798
Explanation: What causes Hubble's Variable Nebula to vary? The unusual nebula pictured above changes its appearance noticeably in just a few weeks. Discovered over 200 years ago and subsequently cataloged as NGC 2661, the remarkable nebula is named for Edwin Hubble, who studied it earlier this century. Hubble's Variable Nebula is a reflection nebula made of gas and fine dust fanning out from the star R Monocerotis. The faint nebula is about one light-year across and lies about 2500 light-years away towards the constellation of Monocerotis. A leading variability explanation for Hubble's Variable Nebula holds that dense knots of opaque dust pass close to R Mon and cast moving shadows onto the reflecting dust seen in the rest of the nebula.

The nebula Messier 78 is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780 and included by Charles Messier in his catalog of comet-like objects that same year.
M78 is the brightest diffuse reflection nebula of a group of nebulae that include NGC 2064, NGC 2067 and NGC 2071. This group belongs to the Orion Molecular Cloud Complex and is about 1,600 light years distant from Earth. M78 is easily found in small telescopes as a hazy patch and involves two stars of 10th magnitude. These two stars, HD 38563A and HD 38563B, are responsible for making the cloud of dust in M78 visible by reflecting their light.

#Astrophotography #Space
It is finished! I have been slowly trying to learn deep-space photography using my camera, a telephoto lens, and a star tracker. It is the most challenging type of photography that I have attempted, and the editing process on this photo nearly broke me...BUT...I got it done. This photo was taken last weekend on Sunday, September 1st into the early morning hours on Labor Day (Monday), September 2nd. This was taken a few miles northwest of Munising Michigan in the UP. This photo combines 66 minutes (33 images exposed for 2 minutes each) of exposure time. The long exposure time allows the faint galaxy light to be collected in the data captured. Photo was taken with a Nikon Z6iii, Tamron 150-600mm lens, & ioptron skyguider pro. 33 exposures set at 2 minutes long, ISO 3200, f/6.3, focal length 550mm.

Andromeda Galaxy a.k.a. Messier 31
……………..............................................
Andromeda, the largest galaxy in the so-called Local Group of Galaxies to which our galaxy also belongs, is 2.5 million light-years away and can be seen (even with the naked eye) in the constellation Andromeda. As general information, Andromeda is about 1.5 times larger than the Milky Way, with a diameter of 220,000 light-years (compared to the Milky Way which is 120-140,000 light-years in diameter) and contains more than 2 times as many stars. Although the first mention of this celestial object dates from 960, the first to give a more detailed description was the German astronomer Simon Marius, in the 1600s.
It should also be mentioned that Andromeda and the Milky Way are approaching with about 100 miles per second, experts estimate that in about 3-4 billion years the 2 galaxies will collide and thus form a new giant galaxy.

Comet C-2022 E3 (ZTF) 22 Jan 2023
First attempt at capturing and editing a comet.
Lot's of new processes to learn and to experiment with.
This was a tricky one for me to process. I eventually ended up with creating a full integration of the star tracked sequence which after initial processing, I removed the stars for the starfield and discarded the residue comet.
I ran a batch Star Xterminate on all the calibrated, debayered and star aligned subframes. These starless subframes were then comet aligned in PixInsight and image integrated using the first frame as the reference frame.
The starless comet was processed separately from the star image and eventually recombined using a Pixelmath combine expression.
Looking forward to the next opportunity to capture more frames in a new position in the sky and hopefully a better result.

The Medusa Nebula, also known as Abell 21, is a planetary nebula located in the constellation Gemini, about 1,500 light-years from Earth. It is the remnant of a dying star that shed its outer layers, forming a complex, glowing shell of ionized gas. Its twisted, filamentary appearance and faint greenish hue give it a resemblance to the serpent-haired figure from Greek mythology, inspiring its name.

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) 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 light years approx and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula
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.[8] The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.

Somewhere out there — a galaxy, far, far away, una galaxia muy, muy lejana — something may or may not be broadcasting. Down here on an unremarkable Spanish street, under a sky the colour of an unplugged television, an entire rooftop civilisation of aerials, dishes, and antennae stands ready to receive. Nobody asked them to coordinate. Nobody drew up a plan. And yet here they are: patient, purposeful, and pointing, more or less, at infinity.
The crane on the right is building an extension to AIJU, Ibi's internationally renowned toy research institute — because even on a street listening for signals from deep space, someone has to think about what the children will play with next.

The Orion Nebula and the Running Man Nebula must be the most imaged nebulas in the night sky. In this project I wanted to get the surrounding dust and gasses that are not normally seen in most wide field Orion Nebula images. To be able to capture the faint dust and the super bright core and everything in-between I took a set of 3 different exposures to create an HDR image. The image required using a masked stretch of 300 iterations to be able to compress all the details into a workable image.
