Markarians Chain Deep Field

[MarkS]

Finally beginning to get those gradients under control.  But I think it will take at least another full re-process before I'm happy.

52 hours of data in 5 min subs at ISO 800 (630 subs!!) acquired over 7 nights back in March.
Modded Canon 350D on Tak Epsilon 180ED with no light pollution filter.

There are quite a few objects there - I haven't counted them.

I might be a few out,  but I counted 439 galaxies.  It's a bit easier with a grid as you know where you've been.

An amazing image.

Loving the annotated version as well..

John.
