Well done Mark.  I think I got it at around 5.30 am on Monday morning, bit it's right on the edge of the FOV and I only managed 2 shots before it got light.  I couldn't image it before that as it was behind a tree.

Very nice shot Mark, good colour.

Damian Peach's comet picture in yesterday's APOD
http://asterisk.apod.com/library/APOD/APOD%20mirror/ap131007.html

It was taken by a remote control telescope in New Mexico:

The T21 telescope - a 17" Planewave CDK:

I feel rather outgunned :-(

Anyway, if it's clear again tomorrow morning and the wind is not gusting too much, I'll have another go.  Mars and ISON are even closer in the sky now - just over 1.5 degrees separation.  See if ISON has changed at all.

It's a nice picture but it's not really "his" picture - Observatory, telescope, camera all belong to someone else in a different country.  All he's done really is process the images sent to him  :-?

Today's APOD
http://asterisk.apod.com/library/APOD/APOD%20mirror/ap131008.html

is also taken with one of those remote scopes -  a very nice refractor in Spain:

He's processed the data sent to him and then added ...

... diffraction spikes!!!  :evil:

They immediately aroused my suspicion because the spikes are far too sharp compared with the overall sharpness of the image as a whole.

Got up at 4am again this morning (Thur) and was greeted by a lovely sky.  By the time I was guiding and focused the clouds came over.  Waited until 5:30 but there were no decent breaks.  So that was the end of that!
