Bobby1970 Posted February 24, 2021 Share Posted February 24, 2021 (edited) I am considering a duo or tri band filter to have a go with my ZWO 178MC. My budget limits me to either the ZWO Dual band, or the Altair Triband. Both can be had for sub £90 which for me, makes it worth a punt. Will there be much difference between the two? Not sure which to go for, I have a few bits of ZWO gear and find it very good tbh. Ideally I want the filter to perhaps allow some imaging time when the moon is up and about. Any advice or experience will be gratefully received. Edited February 24, 2021 by Bobby1970 Quote Link to comment Share on other sites More sharing options...
