Outstanding Igor. Mui, Mui exposure time with a decent aperture and good post processing make for a very nice image! :)

85 hrs is real dedication Igor. :D

I can't say I've seen that colour palette before, not sure if I'm a fan or if it's because it's just different. :question:

A very smooth result :thumbsup:

[Nikolas]

I'm with Andy I love the dedication but the colour palette is a little underdone or pink?
Heap and heaps of detail

Great result Igor, that's a lot of time on your balcony :) :thumbsup:

The 85 hours has paid dividends. A rich detailed faint background has come to life.

Greg.

Wonderful image! All those hours have certainly given a great boost to all those faint wispy details, as well as the background Ha clouds. Lovely work

[Wilsil]

Looks really great, well done

[CoolhandJo]

Very nice. i love this image.

[Spookyer]

Needs more data. Kidding. Great effort.

[Stephane]

I love seeing the extra detail that can be extracted with longer integration. And this image does not disappoint with so much background detail! 85h is serious dedication. Great job!
