Filter choice


Recommended Posts

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 .

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.

Cheers
