The link to the Eta Carina image shows what it’s correction is like with a full frame sensor. It’s been suggested that it has a 55mm imaging circle which I think it could handle quite reasonably with a 16803 and it’d 9 micron pixels but you wouldn’t want pixels smaller than that on such a large sensor.
In essence, it’ll take whatever you throw at it
This model does use FPL-53 but it doesn’t contain natural fluorite.
I have already turn-coated and have a reflector
Selling this as it hasn’t been used for a while. I had considered it as a headacheless DSLR setup but I don’t think I’ll ever end up using it for that purpose when the mount I use has to use a laptop anyway.
