Hi all
I am thinking of getting an OIII filter to help with looking at PN from in the suburbs. I have heard something about some filters not being good for imaging. Now, while I am looking at mainly using it for visual use and I was wondering whether the same filter could be used later for imaging.
I am looking at the GSO OIII filter due to price. Anyone know about the concerns of imaging and OIII filters?
Thanks!
