M51 thru IDAS EAO 1 Filter

The target might be still too low or slightly out of focus.  The image looks a bit soft and low contrast.

Anyway, this was the result with IDAS EAO1 filter at Bortle class 7 area,

m51

BORG 107FL F6(w/7108) + ASI183MC + IDAS EAO1

From my several tests so far, I’m confident EAO1 should work well for most of targets as the utility player in the city. I hope it’s good for some of the reflections nebulae too.

So I can say if someone are looking for the one-piece solution without swapping filters in EAA application, this should be the one.
