Filter choice

[bottletopburly]

I’m pondering a filter now I don’t know wether to go for a baader 6.5 nm or zwo 7nm  Ha filter or an Astronomik Uhc filter this to be used with a zwo533mc , now the uhc is 2 bands so capturing two bands over one I’m kinda swaying to the uhc thoughts anyone .

What are you trying to achieve with a filter? Is it due to light pollution? If so what sort of light pollution?

[bottletopburly]

Not for light pollution I have an idas D2 for that just looking to maybe pull some Ha signal in or maybe some o111

If you're after bringing green and red emission colours to the fore, the UHC is great, but always try without a filter first. 

With your 533, lots of filter-less short exposures will almost certainly be easier to process than long exposure false colour stuff. If you're using it with a refractor, don't forget to get either the ccd version or include a separate ir cut somewhere before the camera.
