A couple of the objects in the M81 group, including M81, M82, NGC3077, and NGC2976.
So I'm learning the rhythm of deep sky object observation...what's up this month, when is the sky dark, and when are the winds calm. It's a little different than for nightscapes, but not hugely. It's a little easier to select a location, but harder to find the right night. I knew I was looking for M81 and M82, but I did not think I'd have enough to capture much else, so the NGC's are a nice bonus. I also managed to capture a bit of the unique features of M82 and NGC 2976.
This is actually the second round of processing. I felt the first round had too much stretching and lost some color detail in the DSOs. The second round, I used some luminosity masks to have greater control over the stretching.
I wonder: how many individuals from these galaxies will look our way millions of years from now when today's photons reach them and wonder how many eyes were looking their way across the void.
Peace and cheers!

I clearly need more data for this one, but this is part of my learning curve for shooting through the Celestron Edge HD 925 with the Nikon D5100. I used a light pollution filter and was shooting at ISO 1600. This is a stack of 30 exposures that were around 55 s in length at a focal length of 2200 mm. I reduced the size of the final image substantially because it was so noisy.
Preprocessing, registration, stacking, and initial processing were done in PixInsight; final touches in Photoshop.

M100 is the 100th entry in Charles Messier’s catalog of 110 “non comet” objects which the French astronomer published in 1781. Of course, he did not know at the time that M100 is a “grand design” spiral galaxy, which contains prominent and well-defined spiral arms, as opposed to multi-arm and flocculent spirals which have subtler structural features.
The spiral arms of a grand design galaxy extend clearly around the galaxy, covering a significant portion of the galaxy's circumference. As of 2002, approximately 10 percent of all currently known spiral galaxies are classified as grand design type spirals (Wikipedia).
M100 is one of the brightest and largest galaxies in the Virgo Cluster and is approximately 55 million light-years from our galaxy, about 166,000 light-years in diameter, about 1 ½ times larger than our Milky Way galaxy.

Seriously - it's just 4 stars.
I tried to process this to bring out some background galaxies, but I only managed to catch three of them with these settings. And they're all super distant/tiny.
Yep - M73 - do not recommend

M74 (The Phantom Galaxy) was one of the first targets of JWST. This image is from my backyard in Long Beach, CA using a Celestron Edge HD 925 at focal length 535 mm with Hyperstar. I used Optolong LRGB filters with an Atik 414-EX camera to get the following stacks:
L channel: 178 25 s exposures
R channel: 65 75 s exposures
G channel: 59 75 s exposures
B channel: 60 75 s exposures
Preprocessing in Nebulosity with dark, bias, and flat frames. Registration, stacking, channel combination, and initial processing in PixInsight. Photoshop and Topaz Labs for final processing and noise removal.
M109 (NGC 3992) is a barred spiral galaxy that appears near the star Phecda - a star in the bowl of the Big Dipper. Recent measurements with the Tully-Fisher relation put it at a distance of 25 Mpc, or 82 million light years away. There are several other more distant galaxies in the same field shown here.
This image was built from the following stacks:
R channel - 84 1 min exposures
G channel - 68 1 min exposures
B channel - 66 1 min exposures
All images were taken with an Atik 414-EX monochrome camera with Optolong CCD filters from my backyard in Long Beach, CA on the night of 2023-02-15. The scope was a Celestron Edge HD 925 with Hyperstar, giving an image scale of 2.48"/pixel. Images were preprocessed in Nebulosity, then stacks were created and combined in PixInsight. After additional processing in PixInsight, final touches were made using Photoshop.

Im now using a ZWO ASI2600MC Pro as my main OSC camera and SharpCap 4.0 as my acquisition software.
Still on the learning curve. After a few goes, I was able to use plate solving in SharpCap 4/ASTAP to GOTO M33 without star aligning the EQ6 mount (3-4 seconds at gain 700).
Optimal exposures are still a bit of a guessing game: 2 minutes (Gain 100, Offset 50 at -5c) seems to equate to 10 minutes on my uncooled modified Canon 80D so I tried 90 seconds here which seemed to work well.
I had less luck with my EL panel flats - I took 50 x flats at 3000ms/2200ms/1800ms and 1725ms but all were too bright and caused negative vignetting! - will try a range of lower values next time. the recommended values from the Smart Histogram tool seem way off to me.
Havent got my Moonlite electronic focuser fully setup to use the automated multi-star FWHM tool either. Will need to bench test that.
Also differential flexure somewhere in the system - stars were oval but guiding good. My guidescope rings only just grip the scope and I think they got loose as the night progressed, the scope got more vertical and temperature dropped.
I ran PixInsight’s FWHM eccentricity tool which told me there was no significant sensor tilt. Have replaced the guide rings with some spares
Apart from that, not too bad!!!
An open cluster of young stars forming in a zone of hydrogen - either as cold dense dark clouds or less dense bright areas of gas emitting strongly in the hydrogen alpha wavelength.
Eventually, the light pressure of ultraviolet radiation from the young stars will push the clouds of gas away leaving just an open cluster like the Pleiades.
Infrared analysis of the iconic Eagle dark nebula shows more young stars forming within.

The Great Orion Nebula, number 42 in the Messier catalogue - this is centred on nearby M43, deQuervain's nebula - the bright pink circle.
Four young, massive and intensely luminous O class stars (in the bright white zone) pump out enough UV and soft X-ray light to illuminate this whole region of space and make hydrogen clouds fluoresce pink at 656.4nm.
Those stars will burn rapidly through their hydrogen fuel and then probably go supernova in just a few million years - burn bright and die young!
Cold gas forms dark clouds, folds and shadows. New stars will form where the cold gas collapses under gravity.

Linear Postprocessing: Rotation > Dynamic Crop > Dynamic Background Extractor (both subtraction to remove light pollution gradients and division for flat field corrections) > Background Neutralization > Color Calibration > Noise Xterminator.
Nonlinear Postprocessing and additional steps: Histogram Transformation > Local Histogram Equalization > Curves Transformation > SCNR Noise Reduction. Multiple passes of Histogram Transformation, Local Histogram Equalization and Curves Transformations were made in small doses.

This is an uncropped field of view of Markarian's Chain of Galaxies in Virgo. Imaged robotically using the GMO System 1 scope in Colorado.
The constellation of Virgo looks out towards a large cluster of galaxies. PixInsight has annotated all the Messier catalogue and NGC/IC catalogue galaxies in field in this image but there are a further 636 small galaxies in the background in the PGC catalogue which would just overwhelm the image so I omitted them.
There are 3 Messier objects in field, the elliptical galaxies M84, M86 and M87.
There are 52 NGC/IC catalogue objects.
The smallest PGC galaxies appear as non-stellar smudges, smears and lines.
