I'm looking at getting some narrowband filters to use with my (unmodded) Canon 6D and WO zenithstar 81. Astronomy .tools suggests I should use a minimum of 44mm filters for my set up.
I'd be happy with a set of the Baader 2" filters, but then there's 'Baader 2" narrowband filterset' and 'Baader 2" narrowband full-frame filterset' which is £80 more expensive. I can't see any other difference than the name and price on any website I check about them. I'm assuming there's more to it, since they also have 'Baader 2" narrowband CCD filterset', which apparently are intended for modded cameras but isn't specified anywhere on any page I can find either.
I'm assuming it's pretty self explanatory, the non-full-frame ones will not quite cover my canon chip entirely, or maybe it's only refers to AP specific cameras? Or maybe the difference in my set up between the two different filter sets would be minimal? Any advice would be welcome.
