Scaled Noise Evaluation Script v2.1 - Bayer CFA VersionĬalculating scaled noise standard deviation… Seeing wasn’t that great – 80-90% humidity with bright moon. Can’t wait to try and get some more data on M31 as well as start imaging M33 Single Sub Analysis A simple DBE worked well to get rid of the green gradient from RGGB bayer and from there it was simply basic editing skills. Overall – the processing of this data is straightforward. Gradient removal was super easy compared to unfiltered M31.

(I will update this post If I can get it done!) PixInsight Workflow Imaged October 24th, 2020 – near 50% moon.ġ40 subs at 90 seconds each at 0 gain on an ASI 2600MC pro – I’d like to try and do another shot at Unity gain with 140 subs and see how/what kind of differences come up. Images we’re all acquired through NINA 1.11 Nightly Build. Telescope sits on an EQ6R Mount in our backyard observatory currently. Galaxies, Reflection Nebula, Star Clusters, Globular Clusters and Dark Nebula imaging. We’re working on some dark nebula imaging that would have otherwise been impossible in our backyard and it does make the dark nebula pop.Įmission Lines Red = Pass through Emission We’ve only been able to test it in our backyard in the “worst of skies” and the weather hasn’t fully cooperated, however, we do agree it does an excellent job with contrast. The filter is designed to enhance contrast and we must say, it does amazingly well. The Optolong L-Pro filter is a light pollution filter optimized around reducing sky glow and common city light pollution bandpass ranges.
