Uhc filter difference

[bottletopburly]

Can anyone tell me the difference between the astronomic uhc and the uhc -e filter, which one would be better suited to using with a zwo533mc.

 

 Thanks Dave

I'd say you UHC is better than UHC-E at being UHC type filter (filter that passes major emission lines and blocks everything else).

Only concern I have about UHC is IR leakage. We can't tell from above graph - but it looks like it passes light above 700nm. If 533 does not have UV/IR cut filter integrated (and as far as I can tell - it has only AR coated window) - you should use one just in case.
