Hi Brent,
Yes I have seen on television all those V8 races, fun!
I see in your signature that you have a RC telescope, I have some thoughts about a GSO 10" RC. I can take my 3" field flattener from my APO refractor and used in on a 10" RC telescope and get very big sized corrected field, maybe as big as 60mm. But just 1x corrector and the focallength will be wopping 2400mm. I more like 1000 to 1500mm range and a wider field and faster.
How do you use your RC, with a reducer or?
This is the field flattener that I maybe can use to a RC telescope:
