Moon in Ha

[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. However, it seems that this approach allowed me to cut through the seeing and atmospheric dispersion so I got a really sharp image.

Canon 450D, astro modded and cooled. I Used PIPP to isolate the red channel as a mono image from about 100 subs and stacked the best.

Great idea and a work around the seeing, It would give you similar benefits to using a IRPass685 filter.
