astrocatinfo Posted December 21, 2016 Share Posted December 21, 2016 Good morning, I'm close to purchase the ASI1600 with the filter wheel and OAG. I have a couple of questions about the filters: Is it worth to go for the Baader LRGB? Or can I go for the ZWO ones (maybe are Optlong?). Some bad reports on the L filter on the later. For narrow band I was thinking on the Astrodons: 5nm Halpha, 3nm OIII and SII. I don't want to go for the 3nm Halpha and the same NII... not high polluted area, less filters. Am I right? Always looking for a balance price-caracteristics. About the size, 31mm unmounted. Thanks so much for your help, Aleix Link to comment Share on other sites More sharing options...
