Comet Garradd re-worked

[lukebl]

Hi all,

I captured a few frames of Comet Garradd last night, despite my optical problems (see here: http://stargazerslounge.com/imaging-widefield-special-events-comets/149839-quick-dirty-comet-garradd-c-2009-p1.html ). Here's 23 x 1 minute frames, stacked in DeepSkyStacker on the Comet.

SXVF-H9, Coma Corrector, 250mm f/4.7 Newtonian

If anyone has any ideas what's wrong with the stars shown on my earlier posting, I'd be grateful for some advice!

And here's a slightly wobbly animation of its movement over 23 minutes.

and, by the way, I think I've finally managed to collimate the secondary properly to get rid of the 'eggy' stars. Just need a clear night to see if I'm right.

That's fantastic Luke. I love it - good job.
