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!!!

I shot this object last year with my Nikon D750, so wanted to give it another go with the ZWO ASI183MC astro camera. A nice result! You can clearly make out the "Pillars of Creation" inside this nebula made famous by the Hubble Telescope.
The Eagle Nebula (catalogued as Messier 16 or M16, and as NGC 6611, and also known as the Star Queen Nebula and The Spire) is a young open cluster of stars in the constellation Serpens, discovered by Jean-Philippe de Cheseaux in 1745–46. Both the "Eagle" and the "Star Queen" refer to visual impressions of the dark silhouette near the center of the nebula, an area made famous as the "Pillars of Creation" imaged by the Hubble Space Telescope. The nebula contains several active star-forming gas and dust regions, including the aforementioned Pillars of Creation.

Decided to bust out the old telescope last night and do some deep space imaging, been a while since I used it and my bigger mount. Of course I'm on call at work which means I can't travel far, have to stay within cell range and be able to get in to work within an hour. So I headed up to my fallback shooting location, Rockport Reservoir. Got up there, spent an hour setting everything up, went to start up my tablet and begin alignment and then I noticed...I was missing the bluetooth dongle for my wireless keyboard and mouse. The stupid tablet touchscreen keyboard won't allow you to use specific key commands in combination, commands I need to do the alignment and get my target in the field of view. So I spent another hour looking for the dongle, realizing it wasn't going to be found, and trying everything I knew to get the alignment to work. No dice, almost decided to pack it up, but instead I did the sharpcap polar alignment and decided to give doing a fully manual mount alignment using a laser pointer. Chose Andromeda because I could actually see it, used the laser pointer and nailed the alignment first try. I just laughed when the first image popped up on the tablet.
I wasted so much time with all that crap so I only got about 100 minutes worth of data. This is stack of 16 exposures, each 7 minutes at ISO 800 with my Nikon D7000 and Astrotech AT65EDQ on a Sirius EQ-G tracking mount. Not the best, but given all the crap I had to go through to get it....I'll take it.

A couple of things about the Crab... First, it's not M1 because it's the brightest faint fuzzy in Messier's catalog, rather it was the first one he recognized as a permanent fixture in the sky which could confuse comet hunters. Second, the "crab" relationship makes more sense when you see the fuzzy gray blob through a small backyard telescope. The intricate structure you see here is a modern construct which is less evocative of crab than some sort of crazy single-celled organism. Messier didn't have the narrowband filters, CMOS cameras, and computing power that lets me extract all sorts of detail from a little backyard scope, too bad for him!

I inverted this image of our sun to bring out the filament structures — which often appear more 3D this way — and colorized it in red to reflect the actual Hydrogen-alpha wavelength.
Captured with a Lunt LS60MT and Powermate 2x with the ZWO ASI174MM camera using SharpCap. Processed via FITS Liberator and Lightroom, this image combines surface and prominence detail into a single frame.
While non-inverted grayscale is the default for solar work, this treatment brings out the Sun's depth and energy in a way that’s both interpretive and grounded in reality.

2 panels for the start of this. I actually have a side panel of the Pelican Nebula that fits in, but I need 2 more panels just to complete that side and another 2 to 4 panels to get the whole complex. Tough right now since the best times to get this guy are past and I might have to wait until next year to finish it.

This is perhaps my favorite astro photo to date. There is some much happening here, with really interesting details throughout most of the frame. Not to overpower this very bright object, I used 30 second frames, ultimately stacking 200 of them! I took darks just to be safe, but the raw light frames were reltatively free of noise.
This is a view of the core of the Orion Nebula, or M42. It's a massive star-forming region some 1,344 light years away. Within it, lies newer stars around which the Hubble Space Telescope has spotted the formation of new planets. these are all being formed as gas and dust within the nebula collapses.
There are three different kinds of shocks in the Orion Nebula. Many are featured in Herbig–Haro objects:
- Bow shocks are stationary and are formed when two particle streams collide with each other. They are present near the hottest stars in the nebula where the stellar wind speed is estimated to be thousands of kilometers per second and in the outer parts of the nebula where the speeds are tens of kilometers per second. Bow shocks can also form at the front end of stellar jets when the jet hits interstellar particles.
- Jet-driven shocks are formed from jets of material sprouting off newborn T Tauri stars. These narrow streams are traveling at hundreds of kilometers per second, and become shocks when they encounter relatively stationary gases.
- Warped shocks appear bow-like to an observer. They are produced when a jet-driven shock encounters gas moving in a cross-current.
The interaction of the stellar wind with the surrounding cloud also forms "waves" which are believed to be due to the hydrodynamical Kelvin-Helmholtz instability. (!)

The Dumbbell Nebula is a planetary nebula and is in the constellation Vulpecula, It’s ~1227 light years away from us. “Plantetary nebubla” is kind of a misnomer because it doesn’t have anything to do with planets, the gasses and colors come from a star that has shed its outer layers. If you squint or zoom in, you can see the white dwarf star in the middle. Charles Messier first noted it in his catalog of objects in the night sky as Messier Object 27 in 1764. The Dumbbell Nebula gets its name from English Astronomer John Herchel, who thought its shape resembled a dumbbell. - You can view this object with a small telescope, or even binoculars.

My mount was polar aligned with SharpCap (what an amazing system for aligning). I'm not comfortable using my SCT as my lens yet. My solution is to piggyback my Sony a7RIII and adapted Nikkor 500mm f/4 P Ai-s on a ADM dovetail rail on the top of my optical tube. For this I used a 1.4x teleconverter making the focal length 700mm at f/8. I used DeepSkyStacker to combine all frames and then 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 stretched in level, then curves. I used the color sampler tool and levels to do my best to keep the background space black. I did mask the nebula and bring some color out on it, while not adding the color to the stars and deep space. I then using my skillset and relyed on Astronomy Tools Action Set, and dodging and burning a bit to give the image the finishing touches.
Here is a quick view of last evening’s 98% full moon. It was so bright last night with the moon reflecting off the snow!

I think I'm finally satisfied with an attempt at this target, everything went well with my focus, temps were low and the skies were very dark at my family cabin near Stanley, Idaho. Earlier in the day was a fantastic solar eclipse and since I had the telescope setup I figured I'd keep it in place and capture the Andromeda Galaxy. I managed to have everything setup and ready to run by astro twilight, guiding was good for a chance (less than 1" total RMS), everything worked out to get the exposures over 5 hours and I didn't forget any equipment.

Processing:
PixInsight used to do flat frame calibration, debayering, subframeselector, registration, localnormalization, and drizzle integration.
In PixInsight I then did a channel extraction for luminence, split the image into RGB and LinearFit each RGB to luminence. After that I did a colorcalibration and then a screentransferfunction (didn't even do a background extraction since there was no gradient and a very flat field after flats calibration).
In Photoshop I did some contrast work with curves, saturation, a high pass filter to generate more local contrast, levels to bring down the black point/background, then a star size reduction. In Lightroom I did some noise reduction and sharpening before exporting.
Now it's time to work on something new....if the skies clear up again.
I managed to grab a few frames of last night's moon before the fog settled in. Here is a three panel mosaic of the 41% illuminated waxing crescent moon. Hope you like it!

Discovered in 1784 by William Herschel, NGC 6979 is a supernova remnant in the constellation of Cygnus and is one part of the more well known Veil Nebula or Cygnus Loop. The source of the supernova was from a star 20 times the size of our sun exploding between 10 and 20 thousand years ago. The thin strands are made of heated and ionised gases. In this image the teal tones represent oxygen gas while the red tones represent sulphur and hydrogen gases. Recent measurements estimate the distance from Earth to be 2400 light-years.

I've been dying to get this with my Celestron C8 since acquiring the Celestron Starsense Autoguider system. Quite happy with the result! I love side-on and almost-side on galaxies look - for some reason it shows off their vastness to me.
With an apparent magnitude of 8, the Sombrero galaxy is beyond the limit of naked-eye visibility but can be spotted through small telescopes most easily during May. M104 is located 28 million light-years away in the constellation Virgo, and with a mass equal to 800 billion suns, it is one of the most massive objects in the Virgo galaxy cluster.
M104 was discovered in 1781 by the French astronomer and comet hunter Pierre Méchain, one of Charles Messier’s colleagues.

A quick grab of Comet C2017 T2 PANSTARRS tonight as it passed a couple of galaxies (NGC3780 & NGC3794, the latter being some 68 Million light years away!). Comet PANSTARRS is quite bright at magnitude 8.3, visible with binoculars from a dark sky site. The faint line running diagonally across the shot and intercepting the comet is a satellite!

Single image of 208 stacked frames created using Live Stacki in SharpCap. Total exposure 825 seconds (13 min exposure), each frame 4 seconds.
Messier 8 and 20, the Lagoon and Trifid, appear so low in the northern sky that it has been a challenge for me to image them from home, where trees impinge on my horizon. This was captured at a Westchester Amateur Astronomers' star party last week. The Lagoon is a large emission nebula formed principally from hydrogen gas; the smaller trifid is a more complex structure featuring an emission nebula (red), a reflection nebula (blue) and a dark nebula which carves the red structure into its three petaled shape. Both structures are estimated to lie some 4-6,000 light years from earth.
Tech Stuff: Borg 55FL astrograph/ZWO ASI 1600 MC/IDAS LPS-V4 filter. 24 minutes X 4 second unguided exposures captured in SharpCap livestacks with dark and flat frame correction. SQM-L readings 20.4 (Bortle 5). Processed with PixInsight, Topaz AI Denoise, ACDSee Gemstone 12.
Our closest celestial neighbour needs no introduction. This gem is the brightest object in the sky besides the sun and seen by everyone on a regular basis, but it's still nice to be able to see it close up and see the details in the craters.
