Hi.
I received this filter on friday. I had serious doubts about the purchase because I intend to use it with my unmodified canon 200d and with my asi1600MM in front of the RGB filters. And I am not sure if this filter will work properly with this set up.
I tried it yesterday and it really has surprised me. This is M42, 25 x 45", no flats, no bias and instead of darks I left automatic noise reduction. Almost unprocessed. Only stacked iin DSS, BDE in pixinsight and curves in Photoshop.
The most suprising thing is that M42 was close to an 80% illuminated moon. Under these circumstances, I think the result exceeds my expectations.
Thanks for looking
