Hi everyone,

Am going to buy a monochrome camera so wanting some filters to go with it. Not sure if I can get away with the 1.25" or if I need something larger like the 36mm?

I'm using a Stellarvue SV105 f/6.2, with an ASI 183MM Pro, so wide field. Sensor diagonal is 15.9mm.

I know I can calibrate out any vignetting but want to avoid as much of it as possible in the optical train.

Keen for any thoughts/advice.

Thanks.
