Title: NGC6888 in Ha Inversed to show some tight doubles
Post by: Rocket Pooch on Jul 30, 2007, 11:38:54
Hi,

I did 5x15 minutes exposure of NGC6888 last night, the image needs processing later this week with the other subs I have taken, and may take.  But just lookk how many stars there are and how many tight doubles.

it is going to be such a good image. Can't wait to see it, even though I wish it was mine!!

Chris - Amazing... & even more amazing considering it was a full moon - The stars are so 'tight' for 15min subs... yikes..! you must really have your guiding sorted..

Like Fay - can't wait for finished image & hopefully some colour as well....

Great shot - John

I need two more clear nights for the OIII and SII to get the set and also the skill to re-align the camera, but I'll have a go.  you never know it might be clear night.

I did find a trick with the HX916, if you cool it for 2 hours before you use it, the thing works better, I might keep it in the freezer in future :-)
