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.

Leo Triplet and Markair's Chain in one night #38436
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.

<strong>SIMPLICITY IS BLISS![b/]



NOW...

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).

Do you have one orignial .fit file that you captured to attach?

I'm surprised there isn't more data with this settings. I'm wondering if something went wrong in your processing. Must you align in pshop? DSS will align. I love using DSS LIVE during aquisition, it watches for new subs coming in from other software and will stack them live on the fly.

Make sure the image is in <strong> sRGB</strong> colorspace before you save. (if so - it will then match after being posted).

Top menu in Pshop - EDIT then ASSIGN and this. (mine is already in SRGB)
