M57 - Ring Nebula

[gonzostar]

Hi 

This is my  attempt with  the ZWO 385MC camera with a ir/uv cut  of M57 in  bottle 5 skies.  

Telescope used was the ES102mm APO AT f7 on a AVX mount

Settings used in sharpcap. 

Gain 60 (is this to low for my camera??)

Integration time around  6 hours using 30s subs. Could it do with more subs? 

Darks and flats used, Finished in PS.

Of course pointers for improvement welcome

 

Cheers

Dean
