Well I tried the FF last night. Removed it pretty quickly as it interferes with the guide camera image badly.

Looks like it's for DSLR shots only.

Anyway, as a test of field flatness I used T47 (separate thread), of which I have posted a picture.

I'll also post an individual sub from the first part of the run, which shows camera tilt. I have a Moonlight, but the SBIG nosepiece has cutaways and the Moonlite doesn't grab very well. I spoke with Ron about this and he recommends buying his flat nosepiece. As the A$ is way up there I'll do that.

Cheers
Stuart
