Description

A real challenge to get this faint supernova remnant.

The O3 is almost not present,while Ha is.

More interesting is that S2 is very strong,i had only 4 x 900 second subs,and it was more visible then the Ha,wich had over 30 x 900 sec subs.

its captured in the period of 29-3 till 13-4,most the Ha channel.
