Description

Here is a better result on this Heart Nebula (a crop on the central region), with 12 frames of 210 sec, 1 of 270sec, in O-III and additional 3 x 30 sec frames broadband ; all @ 6400iso.

Focal is 1200mm at f7.9 - no flattener yet, it makes it a bit slow I suppose.

Light pollution also makes it impossible to go beyond (about) 150 sec @ 3200iso, after it all starts to wash out into pale orange background...

Oh well, I will need filters all the time.
