Thanks for the information.I also have a set of Baader LRGB which I’m very happy with, however unfortunately they don’t do photometric filters. I’m using a Starlight Xpress MX916 which has quite a large chip so I will have to use a 1.25 inch filter.So it’s looking like it’s going to be the Astrodons, and be careful not to get dew on the filter. If I were to use a UV/IR cut filter infront the filter – that should help to protect from moisture and not effect the result or am I being naive?
