-//On another thread we were discussing the fact that Seestar produces an AVI video in addition to MP4 when you request it to save as RAW. They're needed for sun/moon/solar programs like Autostakkert and Astrosurface that quality check and stack the best video frames to produce the best result despite poor seeing.//+//On another thread we were discussing the fact that Seestar produces an AVI video in addition to MP4 when you request it to save as RAW.

 //When I stacked the PIPP converted AVI in Astrosurface and saved the stacked result with no additional processing other than a levels tweak, it produced an image far superior to the one I had produced from the Seestar AVI! //When I stacked the PIPP converted AVI in Astrosurface and saved the stacked result with no additional processing other than a levels tweak, it produced an image far superior to the one I had produced from the Seestar AVI!
