Taken at prime focus with my Cannon M50, 1/125 sec, ASA 100.

I took several shots, but all were too dark except this one. I am using an altz mount, which is easier since I set the alarm for 1am to take this shot. In future, am I better of decreasing the shutter speed; say 1/60sec, or increasing the ASA to say 400?

The Moon was a little low to take a 'great' shot.

The first shot has been cropped and filtered (Neo, then Zeke); the second shot is the original.

The faster the shutter speed the better, so that less atmospheric turbulence
is captured. ISO800 is fine, you won't see any significant noise in such a short exposure. Take several at around 1,000 sec ISO 800, fine tune the exposure by increasing or decreasing the shutter speed. When you are happy with the exposure take a dozen or so, and select the best one. The 1,000 is only a
guide, the shutter speed required will obviously vary widely with the phase of the Moon.
