2168RE: [ccd-newastro] Lunar Images
- May 1, 2001The ST-237 will be good for the job; it has exposures down to a millisecond,
I believe. You should have to down about that low to avoid over-exposure. If
you need more attenuation, a moon filter, or a rotating polarizing filter,
will do the job effectively. If you are close, then your built-in blue
filter should give you a little extra bit of attenuation.
Focus is challenging. If there is any turbulence, it will drive you crazy as
you try to focus. <g> Try to find the rough range of best focus, and then go
for the middle of that. It would be interesting to try CCDSoft's @Focus on
If you have it, don't forget to set the lunar tracking rate on your mount.

Since the moon will be directly overhead after sunset tonight, I
thought it would be interesting to try to capture some images of our
nearest neighbor in the solar system.
Are there any recommendations for successful lunar images?
