All,
Here is a second attempt at the Running Chicken Nebula, this time more subs.
The details of the image are:
Taken with a Canon 350D at prime focus with DSF attached to a Saxon ED80 piggybacked on a polar mounted 10" LX200GPS.
Autoguided with a Deep Sky Imager through the LX200GPS.
The composition is a stack of 15 x 6 minutes at 1600iso and 10 x 8 minutes at 800iso and 2 x 6 minutes at 800iso.
Stacked using Deep Sky Stacker and processed using Photoshop CS3.
Thanks Everyone for your words of encouragement.
I probably did overcook the chook taking the 1600iso's so what would I change in the future? Take all exposures at 800iso and below!
I wouldn't have thought it was overcooked. Perhaps curves could darken the background a tad.
ISO800 is a popular setting. ISO setting is not standard unvariable thing, I'd suggest you chose that setting based on the object. A bight object from a dark site may warrant ISO800. Try that on a dim object and you'll get too dim an image so ISO1600 or 3200 (20D and above).
What about the new 50D? It goes to ISO6400 or something, that could be interesting.
