Congratulations on this brilliant image. I have always suspected that OU4 would be within reach using a weaker Oiii filter than the Astrodon 3 nm Oiii  and you have proved it. OU4 It is by far one the most difficult DSOs to image due to it being ultra faint. Very well done.

Well done indeed. Your signal strength on OU4 is incredible. Brilliant. This really is a faint target and you have it looking really strong. I'm not sure how you managed it but you certainly did!

I find the contrast in the Ha layer a little lacking by comparison but since you are imaging at this level I'm going to be honest.

This certainly deserves a magazine publication.

Thx all! 

Well, Ou4 is really faint. Thats why i had to push the nebula quite strong. thats why it is a little bit smoothed.

the second problem i have is my quite bright night sky due to light pollution of the city of vienna and the airport.

this is how it looks like: http://www.astrobin.com/189696/

even more I'm satisfied with Sh2-129 and Ou4. 

but still i should get more exposure time. :)
