Hopefully the FLI camera will have less back focus problems?
Will it work with a 3" focuser/coma corrector?

The FLI Microline 8300 has 16mm of back focus (the chip is 16mm inside the camera in other words). The SX Mini USB filter wheel is about 53mm from one side of the adapter to the sensor surface of a FLI Microline with a 50mm male threaded adapter (I am not sure if that is the SCT adapter they refer to on their website).
So if the scope has 90mm backfocus it should have room for the MPCC within that.
The SX Mini USB filter wheel seems well built plus a built in OAG would be really handy.
My usual setup is an Astrodon MMOAG which is very solid and a reliable unit but it takes about 35-40mm of backfocus. The FLI CFW 4/5 takes up 20mm or a tad less.
