Difficult to get a good image with the light pollution but there you go.
10x15min subs and 10x20 min subs with 10"GSO RC and QSI583WSG

Allan, that looks very clean, well done!

[RickS]

I don't know how you manage to capture so much from the city, Allan! Nicely done...

[Larryp]

Looks good, Allan!

[peter_4059]

nice tight stars - that RC looks to be working well.

[batema]

Very nice indeed.

[Stevec35]

Works for me Allan. Nice detail.

Great detail. :)

[prokyon]

Very nice, a lot of details!

JJJ and the rest of you guys, thanks for the comments as they are appreciated.
I think that the observatory shields the scope from a lot of the neighbourhood light pollution but I cant do anything really about the rest of it and just have to get as many 20 min subs to tease out the faint material.
Coulour will have to wait til the moon goes away.

Great result, very smooth and detailed.
Do you know if 20 minute subs are optimal for your setup? I experimented and found 5 minutes to be optimal with my 10" and QSI683 which should be similar to yours I guess. I can squeeze more faint details out by stacking say 10x 5 minute subs than with 5x 10 minute subs, S/N in the final image is simply higher. The more light pollution there is the shorter the optimal exposure will be, so I'd expect 20 minutes to be good for a very dark site but not if you are in the city. Anyway, just a thought :)

You probably are correct, Rolf as Ive seen some nice images from 5min subs. Its something I will have to look into but the histogram of the 20 min subs is nowhere near saturated and is still in the lower 1/4 of the hystogram. Will have a trial tonight on NGC1316 to see how I go.

Plenty of detail in the arms considering the light pollution from the city.

Nice one!

Thanks Geoff, just trying my best.
