Description

TOA 130 at F7.7 (unreduced-1,000mm focal length), ASI 1600mm cool pro, with Astrodon series E RGB and 3um Ha filters.

Red 101 2min

Green 56 2 min

Blue 109 2 min

Ha: 48 5 min

Lum: 82 2min

I thought I was way short on green subs, and without a true luminance I did not have much hope. got lucky to a degree I guess. More data will certainly improve the image--but I think I can live with it.

I added 41 2min lum subs.
