 I am going to post my dismal results from last night......not because I am proud of them.   My setup has it's limitations, never more evident than with these images.    There was terrible sky glow, but that is not an excuse.   I should have known how it was going to go when I couldn't see the Veil in a 50 second exposure.   I used nearly an hour of data, but I don't think more time would have made a significant difference.   On the other image of the NGC 7331 cluster, the objects are just too small.   I need more scale with my low res camera.......some of the detail got lost in the light gradient.   More time may have helped this image.
 
Setup:  130mm f/5 Newt, CG5 GT mount, StarShoot II color
 
NGC 6960 the western Veil nebula:   62 subs @ 50 seconds per sub   The image pretty much speaks for itself.  I either need to shoot this object from a dark site, or attempt a longer exposure with a UHC filter.  Sky glow just washed out the nebulosity.
 
NGC 7331:  (and friends)   58 subs @ 50 seconds per sub.   Lots of light gradient.   Minimal detail.    Mag. 9.5,  10.46 arc minutes, 46 million light years distant      Surrounded by tiny magnitude 15 galaxies......apparent size .2 arc minutes.

Thanks Miquel. My setup seems to work best with objects that aren't too big or too small (apparent size. It does pretty well on some things and poorly on others.

The conditions at my house are never very good....too much light polution in the area. But, some nights, if there is a lot of moisture or haze in the air, the skyglow is particularly bad. It's just something I have to deal with.

I have a skyglow filter and a OIII filter. They are not specifically designed for photography, but I am going to try them on faint nebulas (like the Veil) to see if they make a difference.

I think it is a pretty good shot given the bad sky conditions, I can only imagine what you will get once the sky clears out.
