Ok, sounds interesting. Thanks for the reply, Kevin.
The ASI174 mini has 5.86um, while the ASI1600 has 3.8um, so 5x is about F29 and F19 respectively.
To get that with the RC10 at F8 is about 4x or 2-3x (probably 3x?) and for the Sharpstar at F6.5, I'd need 5x or 3x respectively (for each camera). Looks like it might be easier to go with the RC10 and ASI1600 at 2x or 3x if I used my current gear (would obviously have to use filters and process appropriately).
If I got the ASI462, I'd only need 2x for the RC10 to hit optimal focal ratio formula. Might try more with my current gear first to see if I can get some results.
How do you go about focusing? How can I tell I've got the best focus for the current conditions? How much data do you capture (frames?) for an image?
