i know, i know, i know, i will be very excited when i get to tony's stage, but it is really great that i almost take possesion of other forum member shots as if it were my own. have a little play in photoshop, tinker here, tinker there.
No worries guys....I will up load the original to my webby as file "Test 4"
You will see what I mean about flattening the field as its got a prenounced circular effect that dissapears to the edge...any help with this is much appreciated....or is it jst my light polution...maybe I need to take slightly shorter exposures...
Tony when I imaged this target earlier in the year I went with 4 minute exposures and got them to total 41 minutes. I had to get my polar alignment pretty good though as I did not have a guide scope at that stage. Also I suggest a lower ISO around 600. You will get great images with any subs totalling more than 30 minutes. To create flats you need to make a light box and as far as dark frames are concerned I just use the noise reduction system in the camera and find that this is nearly as good as creating darks during the night. I am not certain whether the 20D has NR reduction in camera.
Anyway mate, you are doing really well with your images and I suggest that you use that camera also for terrestrial shots. It is a fine camera and capable of much more.
There's great info in there Tony. I tried a Jerry Lodriguss' unsharp mask technique on it. I've not tried it before very successfully, but I think if you muck around with it you'll be able to pull heaps of detail out. Didn't do much else with the colour except my usually fluffing about with levels and curves. Oh and I cropped it as there seemed to be quite a bit of vingetting.

I got heaps to learn and need to try different techniques...I noticed whilst using the 6.3 FR the ISO needs to be much lower then at F10....2 minutes at ISO800 just made it look like a light bulb but at f10 was much darker.
