Well, particularly for my 85mm refractor, which has an .80 reducer/flattener, dropping me down to a focal length of 432 from 532 not only would boost imaging time, but also might negate the need for my desire to acquire a wide field instrument. But at $500, is it really worth it?  I know money in this hobby is hard to gauge, like, it's a hobby so it is worth it if it ends up being used more.   But I am not even sure how well it will mate with my current optical train, and whether previous users of the APEX have reported good results.

I use the apex-l version with great success. The only issue with the apex is its 48mm. Would be nice if it was a little bigger for larger sensors but oh well. With apsc there is a bit of vignette but it calibrated out.

How it pairs with each scope really depends on. The scope. I paid 300 initially for a fr that didn’t work too well so 400 for one that works great and didn’t mean another scope in my inventory is ok.

Dean told me they were working on a FF version, could be a while.
