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

[Peter Ward]

A remarkable effort. 80+ hours....wow!
Well done

Very impressive!

85 hrs is real dedication Igor.

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.

A very smooth result

[Nikolas (Nik)]

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

[strongmanmike (Michael)]

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

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 (Wilco)]

Looks really great, well done

[CoolhandJo (Paul)]

Very nice. i love this image.

[Spookyer (Brett)]

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!

Many thanks to everyone for the kind words, it's very inspiring!
