CORRECT PLACEMENT OF A BAADER FILTER
CORRECT PLACEMENT OF A BAADER FILTER
Hi all,just quickly wanted to ask which way should you place a Baader 35nm Ha filter,that is which side should be facing the sun(the red side or the very reflective side?).It would be acting as a sub aperture ERF.Thanks all,Nick.
