Orion Nebula HDR with ZWO ASI174MM

james1ca

Taken just over one week ago with an ASI174MM using subs from two nights with a 5", f/5.2 refractor and a set of Baader RGB filters. A combination of three different exposures, 15 seconds, 4 seconds, and 1 second giving a total integration time of just under 72 minutes (approximately 23 minutes for each R, G, and B channel). Dark fields and bias applied, but no luminance frames or Ha (i.e. plain RGB).

Yes, it was taken at the prime focus of a Tele Vue NP127is.

Yes striking is the word.

Thanks James and hope to see more of your images and descriptions.

Everyone, thanks for the notice.

newest FC has a new feature to fix the random horizontal line problem

maybe you would like to have a try

Improved software is always nice to try. However, what is "FC"? Perhaps that's Firecapture, but I think I'm already using the latest beta of that software and I'm not aware of any offline image editing features in that software. However, the Autostakkert beta has some experimental tools to handle column and row noise correction. Also, Startools has a banding reduction module that seems to work fairly well.

I'm already using the v1.0.1.10 ASCOM driver but is there some other software that addresses the row noise issue with the ASI174MM?

sorry, it should be AS!2

I think the best way should be exposure longer to let the sky glow cover the row noise

stepping beyond

Awesome image !
