Description

Another repeat target trying full FL (780mm) using a straight flatenner on my APM130 F6.

Again I dont think the extra FL buys me anything over using the scope at 0.75 reduction and 585mm... anything gained is currently overshadowed by less signal and more tracking issues.

I also think I've over-exposed here in my Bortle 7 skies a little with 90s for L and 180s for RGB.

Stacked in APP and combined a processed in Startools.
