Please don't laugh but this really stuffed me up!
Got to organise my Baader 2" umounted NB filters set into the FW carousel and somehow muffed up and in the process of re-inserting/installing them again I got totally mixed up as to which filters are which!!
Rather a silly question but being a noob about this, how does one suss out which is which? I think I know the Ha one but cannot differentiate the other two being either SII or OIII - they all look similarly highly reflective!!
Another noobie query is which way should the filters face be deemed to be correct? In other words is there a "front" and "rear" surface as such - with mounted filters at least you know which is front or back as the filter rings indicate as to how you should face the filters in the carousel
Any suggestions would be greatly appreciated
