There is a beautiful supernova remnant in Cassiopeia called CTB1 that I really want a good image of - BUT - my local skyglow stops me from getting it :cry: Even with half hour subs on the Hyperstar 3 it still ends up as an extremely faint red smoke ring (off to the left of the attached image). I have given up on this one and admit defeat - my first comprehensive deep-sky imaging failure :cry: :cry: :cry:

Well, I can see a faint red ring ... so it's not an absolute failure :)

I wish I can fail at this level :)

Guess it depends how much you want this shot. Is it worth packing a ton'o'kit into the car and driving to middle of nowhere at night?

I want it that bad Popo - but I think the easier way would be to hire some time on a scope, it's actually not that expensive.

Heh..your level of failure is wayy above my level of success. I admit defeat in the realm of astro-photography even before trying!

Nice image :-)

Yep every little dot, white, red, orange or blue is a star. There's so many because:

1) This is in the Milky Way.
2) It is a VERY deep exposure.

Take a look at the New Forest Observatory web site especially images in the Cassiopeia region which is in the Milky Way. If you check out the nebulae IC59 & IC63 around Gamma Cassiopeia you will see just as many stars :D
