Hi ZWO staff,
I'm interested in buying an ASI1600, EFW mini including 31mm filters.
I'd like to attach it onto my Epsilon130 that works at f/3.3
I was wondering if it works without vignetting.
Cheers
Peter
Hi Peter
I recommend 36mm filters, it will get much flat frames.
Hi Sean,
thx for your reply. What filter size would you recommend if the ASI183 is used instead. 1,25" or 31mm unmounted?
Cheers,
1.25" will be good. But if considering about use 4/3 inch sensor in the further, I think 36mm will be a final solution. You will not be afried of changing cameras.
I use 31mm unmounted filters with the ASI1600 and ZWO filter wheel at F/3 and don’t have any issues. The sensor is more square that the KAF8300 chip and so easier to illuminate at low focal ratios, it also keeps the filter cost down especially if they are Astrodons !!!
