Hi,

 

A short integration of this iconic target.

Shot with the 80ED at native FL (600mm) to get the best resolution but at the cost of a ton of coma... The scope is also prone to blue bloat (B channel was also softer)

I opted for an ice/blue palette to avoid the image to be too dull. I hope you'll like it.

During capture I tried to minimize at most so it enables to remain nice star colors.

 

It is best to look at the 3097x2310 image on ABIN : https://www.astrobin.com/410388/0/

Clear skies to all

Axel

Thanks Kathyastro.

The mix between short exposure + good tracking + deconvolution help a lot to get sharp stars.
