My very first Mars photo. Remember when I said I needed to get up earlier? I shot this at 4:30 this morning.

It's OK, but I think I can do better. I'm not sure how, though, using the afocal setup. I just can't seem to get a sharper focus. I'm using a Hartmann mask, so I'm fairly confident my focusing is about as good as I can get it with the stock focuser. Maybe it's the zoom level on the camera having to be so far in in order to get a decent image size. There's likely some field rotation--this is 20 frames @ 1 frame per 5 seconds, so it's nearly 2 minutes in alt-az. I'll try next with the wooden wedge, but not until I practice aligning it first.
