Keyhole in Hydrogen Alpha

This is the last from my keyhole serie. I did some Ha as the moon was getting a lot brighter and the seeing wasn't too bad the first hal but somehow got really bad after a while so I had to throw the second half of the subs. About 1.5h worth out of 3h.

I used the Ha channel to blend details into my NIR version and also did a stand alone. Little noisy but still some cool details.

There's a HD version here. [1.4MB]

I'm probably at the limit of that refactor but the exercise was a very good wake up call on the guiding side of things. Will try with larger aperture from now on, and the AO.
