Astroarg Posted March 31, 2021 Share Posted March 31, 2021 So my previous image (81% Moon - 24th March 2021 - Lunar & Planetary imaging - The Backyard Astronomy Space) seemed to be missing colour, and as I looked back through my prcess, it seems loading into PIPP to create a new SER file is where my colour goes missing. Here is version 2.. same tech details but a change in the process Altair Astro 72EDF Altair Lightwave 1.0x flattener (left in situ) No filter Altair Astro 183C Pro-Tec @ -10 DSD AF3 ascom focuser iOptron CEM25P mount Altair Astro MG32 guide package (not used) captured in SharpCap - 15ms exposures in 5 min SER file pre-processed, aligned and stacked in AS3! (SKIPPED PIPP!) post-processed in PS approx. best 200 frames Shot from my back garden, Ramsey St Marys, Cambs. Bortle4 6 Quote Link to comment Share on other sites More sharing options...

That's a nice image! In AltairCapture 8Bit mode, I found it helps to run the camera with gain or exposure set, such that the histogram meets the line at less than 100 levels. I often aim for about 60-80 which is pretty low - but that means I can stretch without blowing out crater walls and other bright features. The resulting .SER video looks quite dark in Autostakkert but to see what you're doing, you can increase the brightness when stacking without affecting the image data. It's that small +/- button thingy, top rightish menu. Hope that helps a bit. Here's a screengrab showing my histogram: Quote Link to comment Share on other sites More sharing options...
Astroarg Posted April 3, 2021 Author Share Posted April 3, 2021 Hi Nick Great, thanks for the reply.. I shot in 12bit, don't think I needed to.. I thought it was 8bit losing the colour but turned out it was PIPP.. Next time I get a chance with moon shots I'll give this a go 🙂 1 Quote Link to comment Share on other sites More sharing options...
MarkAR Posted April 5, 2021 Share Posted April 5, 2021 Wow, what a difference. Makes the previous image look quite ominous and dark. 1 Quote Link to comment Share on other sites More sharing options...
