advise on filters
hey all,
I'm looking at getting a couple of filters to enhance my DSO viewing experience.
Looking at an OIII and H band filter (narrow band, I think), and PERHAPS one Broadband filter.
My question is this - Where is the best place to attach a filter? I know general consensus is on the eyepiece itself, however I'd like to know if filters can be attached to the nosepiece of a star diagonal?
the visual back on my SCT is a Baader Click lock, so my star diagonal has a slide in nosepiece. the inside of this tube is threaded to allow for 48mm filters.
Can i screw a filter onto this?
what are the disadvantages of attaching a filter this way?
Just wondering as I've not seen it discussed.
cheers
Jeelan
