Hello all,

 

This is my last image I made with my 16" Newton and Moravian G4 CCD camera from France.

 

This image is a composite of HaOIII for the luminance and HaOIII-rgb for colors.

Abell 85 or CTB1 is a supernovae remnant wellknown and We 2-262 is a possible planetary nebulae on top right of the image (discover from 1966 by Weinberger, R).

 

There is also this name for Abell 85 : G116.9+0.2 from Green Catalog.

 

A surprise also in this image at the left bottom you can see a small OIII filament :

 

I hope you will like it for this natural colors and details.

Hi, Nicolas,

 

great result! waytogo.gif

 

37,5h integration time under dark skies, very nice basics for post-processing!

The processing must have been quite easy...smile.gif

 

cheers

Andreas

Hi Nicolas,

 

what a great shot. I like the natural look of your processing. The inverted version is also very interesting. 

 

Best regards 

Andreas

Thank you very much to all for your nice words.

Small precision for We 2-262 it is now a cometary globule.
