SII Filter

Need to know about how to work that new mount or scope? Got tips on how to make it easier?

SII Filter

Postby Dark knights » Fri Mar 09, 2018 7:08 pm

I have Astrodon HA 3nm and OIII 3nm filters, Looking for a suitable SII to go with them. Now the obvious choice would be the Astrodon 3nm to match the other two, but would there be any drawback to getting the 5nm with the Semi light polluted UK location i am at? (large town). Also there is the Chroma range, Would they be parafocal to the Astrodon?

Cheers,

Jason.
