ASTRO: Comet Holmes - 11 Nov 07 - 2:30 UT

Image made from seven 1-minute exposures thru a VERNONscope Brandon 80mm APO
refractor using a Canon Rebel DLSR. Even with a 40mm Meade wide-field
eyepiece the comet just barely fit in the field of view with the 20RC. I
have some more data from last night, but I doubt that I'll get anything much
better than this.

nice one george! also nice to see the comet moved a bit when compared to my
image, which I took a few hours before you did.

Very nice picture George. Quite similar to what I got with my EOS300D
through a 6" F/5 Newt.

Nice image George, also liked your DSLR full frame. Puts the comet in
context.
As I write this now (13th Nov at 22:47) I'm acquiring a series of RGB frames
with my ED80.
I'll post it if it turns out okay.

Regards
Dave Cash

Dave,

I was dodging clouds to take that wide-field! If I get another chance to
image the comet with the 80mm Brandon I'm going to try a screw-in 1.25"
Barlow that came with it to see if it reduces the field curvature. Of course
it will also reduce the field of view.
