Hi,
Here's another wide field, Rho Oph.
This is one of those area's that I find difficult to process, this is my best attemt so far, out of six.
When imaging I tried a ten minute exposure at ISO 800 and a five minute at 1600, in both there was too much fogging of the background. So I stuck to my tried and true five minute ISO 800.
There's still a bit of noise in this image so it needs some more data.
Telescope 8” f/4 astrograph on a HEQ Pro 5 mount, orion mini guider.
Unmodded Canon 1100D piggy backed 55mm at f/5.6
7 x300 sec subs ISO 800,
24 dark frames, 9 flat frames and 11 bias.
Stacked in DSS and post process in Phototshop.
Cheers,
Justin.
