The details are awesome! It is funny to read "unguided" . ASA makes it possible.

Stunning. You have an extraordinary signal there, one of the deepest I've ever seen. It really does show what is there if you give it the time.

Thank you all guys

My subs was 34x600sec + 6x1200sec (unguided).

I'm still testing the tracking accuracy of my new mount so this photo was one of my tests.

Franck congratulations for your patience but something bothers me in your final photo.

I think that you can get more juice out from this mosaic with a better process of course.

Anyway keep shooting

Hello Aggelos,

I have done one more time my processing and you could see 3 different version : http://img10.imageshack.us/img10/3274/panorama9deic4342c.png

But, I think except my process, we can't compare our image because you have 7,5 hours of exposure in this deep field and if you have look correctly, I only have 2 hours for each area !!! So, with 5,5 hours more of my, it is normal way than you have much signal !!! With my sensor field, I can't do it in one time. But I'm sure if I do 7 hours of exposure, I could get the same result !
