Leo Triplet and Markair's Chain in one night #38335
While looking for an astrophotography all in one solution that worked on a Mac I found INDI/Kstars/Ekos/Stellarmate. Great community BTW. For around six months now I've been reading and learning what the software can and cannot do. To my surprise I've found that the software, if used properly, will do exactly what it is designed to do. Almost all the errors I've frustrated over have been due to unrealistic expectations on my part and user error. Go figure. Anyway, I thought I'd share a couple pictures I got last weekend with a new scope. My processing skills with Pixinsight are very weak still but that's a whole different project.

Each are 100 60sec subs using a one shot color camera (ASI183mc-pro) attached to the front of a 8" RASA astrograph, autoguided on an Orion Atlas eq6 using a Stellarmate for everything (autofocus, platesolving, guiding, capture, dither...) from inside my house. The moon was very strong (80-90% full). Pretty cool.

Ron Kramer :

Thanks for that edit. They looks soooo much better. Any chance you could list the edits you made? Also, that was linear data so I'm guessing that doing some of that in the pre-stretched state would really be an improvement?

Yes - and PRE .JPG state would be a HUGE improvement. There is no list of steps - as it's different for each image. But for pixinsight google video lesson on Dynamic background extraction and multiscale linear transform tools.

I see walking noise trails. Are you dithering during image acquisition? Did you apply flats? I ask because it appears bad flats were used. (I rarely use them) and only use if needed.

I have a 11" RASA here that I've yet to really put into use other than some initial tests.

The first thing I did when I started with PixInsight was to go to these tutorials:

www.lightvortexastronomy.com/tutorials.html

They explain a LOT about image processing and also about the shooting process. You’ll need bias, dark and flat frames and especially the Pre-Processing tutorial very well explains how to process all the images and come to a good looking result.

So.. this was my plan to image same objects this week. I did.
Very light polluted area.
My scope is a modest AT72EDII F6. Nothing close to RASA F2.
The Leo Triplet came out not too bad.
But the Markarian's chain... at 120 sec x 60 it was nothing to look at.
Tonight I retried at 240 sec x 40. Better but not much.
Next week I'll drive 8 hours away from home to a dark place and see what difference would that make (hopefully everything will cooperate).

Max - post your version - I bet we can help? my color camera is VERY susecptable to light polution. If the moon's out - forget it.
So I shoot mono mostly for my bortle 6 skies at home. (in my dome).
I just moved the color camera to a portable setup that I put together. A 80mm APO with .8 reducer, ASIair, OAG and cheap avx mount.
ITS GREAT FUN testing it in the driveway as I get it configured. My plan is to bring it to my daughters which has Bortle 4 (I can see the milkyway there)
NEVER at my place. I had thought about selling the camera, but figured I'd try this first. The simplicity of the setup makes it fun again.

Early stages - in the photo. I wanted to pull that beast of a guide scope and put a OAG on it.
I'm now testing spacing/focus point for guide camera as it has to match the primary.

Hi Ron/All,
Here's my Markarian's. I actually expected a better result. The sky was without clouds but hazy - maybe that's why.
AT72EDII, ASI294MC @ gain 200. 240 sec x 40. Optolong L-Pro filter.
Stacked in DSS. Minimal processing: RGB aligned in Photoshop and saved as jpg.
Can you turn this into something interesting? I am getting too much noise after contrast stretching (using photoshop). Thanks!

Here's my final result. Photoshop contrast stretching + Noiseware noise reduction.
(my images look quite a bit darker when posted on the internet - something is not right with my photoshop color profile or something).
