Not at the moment but it appears to only have started with the most recent release of the Infinity software, which did fix a couple other problems but might have introduced another!?

I'll shoot some subs using ATIK's Artemis software next time out and see how it compares? I might also fire up SharpCap and see how it fares? Since the ATIK's Artemis software and the Horizon ASCOM driver haven't changed, both Artemis and SharpCap should work...

The banding is quite serious as shown below:

I setup my CGEM early last night based on reports of clear skies and decent viewing.
The report mentioned light winds but by the time the sky cleared the wind was hitting 10 to 15 MPH.
Still I did a 2 PoleMaster alignment followed by a 2 + 2 star alignment.
Go to when I finished was darn close to centered.
I wanted to shoot the Whirlpool Galaxy but clouds had other ideas so I went to Bodes and the Cigar Galaxy again.
I dropped the ISO to 400, set my aperture to f:/6.3 and shot for 140 seconds.
Tracking was spot on and this is what I pulled.
I am going to post uncropped and cropped.

A great Moon shining through thin cloud lighting up the sky, not to mention atmospheric motion bouncing stars around the sky...

Set up the ATIK color Horizon camera on the WO Megrez 90 with a 0.8x flattener/reducer and STC Duo-Narrowband filter (Oiii and Ha) to partially reduce (Moon) light pollution, mounted on an AVX mount, no guiding. A quick polar alignment with PoleMaster. A star alignment with StarSense. Ready to go!

I first shot Sirius to check atmospheric stability; not a pretty picture but a colorful time-lapse, at: Sirius In Motion.

Then I went after the Alnitak region (Flame and Horsehead nebulas), did a Bahtinov mask focus on Alnitak, captured a real time aligned / stacked image (19x30sec.) using the Infinity capture software and saved the subs (50x30sec.). 38 subs were later processed in PixInsight. The results are not at all great but the -15C (5F) outing under the stars was invigorating (and helped cure my cabin fever)! My eldest granddaughter also enjoyed the outing away from the noisy relatives in the house.

If nothing else, I was fairly happy with star shape and focus as well as controlling flare from Alnitak (I can easily see its twin!). As for nebulosity, I'm surprised I actually captured any!!

Enjoy!

The clouds just do not want to go away. No capturing new images here. Decided I wasn't very good at using Nebulosity, so went the Tutorial Videos route.

Here is one I redid using a stack of 10. Camera was an Olympus EM5ii which has been IR modified, and a Samyang 135mm f2 lens. The exposures where only 8 sec each at ISO 1600 which wasn't enough to pull in the outer regions of the disk of Andromeda. I can tell that my focus was off just a tiny bit when I look at the faint stars. And just to the right of Andromeda, I see a vertical band of horizontal stripes, that must be processing artifacts.

But I did discover that there were things about Nebulosity that I wasn't doing right.

Attaching the same image as done using DSS for comparison. I actually think DSS did the better job. The stars are predominantly yellow due to the IR conversion of the camera.
