I took a quick shot of Omega C tonight and i think I can see some improvements over my first on ethat I posted a little while back.
20second exposure only, ISO 3200 on EOS 20Da, C9.25 F10 (wish the mailman would hurry up with that focal reducer...). Some photoshop and noiseware (but i find neither PS or NW made much difference this time on Omega).
I attach the old one from may 6th and the new one, May 19th...in case noone else could see the difference I made sure they had a small caption/label at the bottom of each pic to tell them apart.
cheers

The smaller star images in the second one is good.
Perhaps a filter to stop star bloat at longer exposure will help. I am sure many here on IIS will be able to help in this area. I am only guessing but a Ir/Uv cut filter may be the answer.
Well done it's a great improvement, I agree the new one is better, the stars are tighter and detail is great for 20 sec exp.
When you get the F.Reducer, next time go a bit longer and drop the ISO, it should improve even more.
Sharper stars and less drift but you shouldn't get any drift with only 20seconds.
I agree with the others...lower ISO and slightly longer exposures...with the Omega Cent you dont need the exposures to be long but around 1 minute would be the go.
Thansk guys!
I'll do all that.
Not sure why I'm struggling with the drift align so much (the fact that i dont really know what I'm doing doesnt help ! :] )
I'll get there eventually!
thanks

Frank I was just like you...I got Paul(1Ponders) to come down from nambour to help with my Drift align...once I saw how to do drift aligning it was made easy.
Take John up on his offer and good on ya John.
I too like to see it done and learn alot quicker instead of looking through and reading some instruction book or manual on how it's done.
