Just sqeezed in some more time to process another image. Here's the Jewel Box info below:
Celestron 10" F4.7 with Canon 350D Unmodded
Autoguided Orion ED80 + Meade DSI II
Baader MPCC/UHC-S
10 x 2minutes 30 sec ISO 800
Flats/Darks subtracted.
I have no idea what that streak is on the left hand side. i don't think it was a satelite as the streak doesn't go right through the screen. ok.. i better goto sleep.

Love the Jewel box! Good image. Presumably the streak is a meteor and only on one sub (?). How did you combine the 10 subs? Averaging would make a bright streak in one sub appear very faint.
Very nice Eric, the Jewel Box is certainly a beautiful cluster.
Like Mike said, the image is a little too much cyan biased but that can be balanced out.
cheers guys thanks for your reply. totally agree it is too cyan. will fix that. i think the baader uhc-s filter made it all cyan and because it is an unmodded camera. the streak appears on all my 10 frames. it was stationary. I shot more than 10 objects last night and the streak only appears in the jewel box. interesting.. not powerlines, not cables hanging over the scope etc etc
Very nice Eric!!.. I have always loved this little cluster but never have imaged it..
Ohh that strange line is a diffraction spike from a nearby bright star out of your field of view. From beta crux? maybe.
You have certainly done a marathon last night...
Cheers Gary
