Moon in Ha 14 July 19

[Stub Mandrel]

Why image the moon in Ha?

Because my scope was set up and focused but it wasn't dark enough to start guiding reliably.

I Used PIPP to isolate the red channel as a mono image from about 100 subs and stacked the best 70%.

This one has really responded well to 3x drizzle. Lots more detail. The png is to big to load, so here's a jpg (sadly loses some of the detail gained!):

Ha Moon - I haven't tried that but I suppose it helps moderate the brightness.   Thinking back, the last moon 'mega-stack' that I shot just used the Red Filter... That gave some good detail too.

I suspect it eliminates atmospheric dispersion by creating a narrowband image, giving a sharper result.
