I have heard the cheaper filters can have lower light transmission levels due to cheaper coatings.
I am not fussed with spending a bit more to get a Baader filter. Figured it wouldnt hurt to ask and see if anyone has a second hand one that they dont need. If not, I will just go and buy one new.
Still searching, also if anyone happens to have a Baader H-alpha 7nm or similar quality filter I would be open to buying one as well. Keen to maybe try some HaRGB imaging.
