Quick one to know the limits of the 1.25 filter.
I'm hoping to upgrade my narrowband set to a 3nm set. my current setup runs fine with 1.25" filters. So obviously that is what I'm looking at to purchase. But, in the back of my mind, I do think that "eventually" I will upgrade my camera to something like the ZWO 2600, with an APS-C sensor. So I do want to upgrade while keeping "future-proofing" in mind, but also want to reduce cost where possible. (this hobby is expensive enough already)
the diagonal of that camera is 28.3mm, a 1.25" filter is 31mm.. so in theory yes, but the bezel will reduce that a little so it might be too tight.
So far I've mainly found answers for this for the APS-C of a DSLR. I've used a 1.25" on my DSLR aswel, and there is some clear vignetting, but the sensor is mounted very deep in the camera, and with a dedicated camera, the filters would be closer to the sensor, perhaps reducing the vignetting.
Rather hear from someone with experience before I start purchasing things.
Wether or not a ZWO 2600 is manageable with 1.25" filters, - if flats do a good enough job to deal with it, - or a slight crop is already enough.
I do understand that a 2" setup would be better. But… as upgrading to a 2" filter setup would come at significant cost + a new filter wheel.. and all of a sudden we're talking $1500+ on top of what I'm already considering spending.
Thanks.
