I've have the Starizona SCT corrector. It seems to work fine with photos. I've
used it once or twice visually and it seems to work OK. It's pricier than a 6.3
corrector from Celestron or Meade. But, you get what you pay for. It's easier
for me to use a 72 degree 36mm Hyperion on my SCTs. That gives me about a 6
tenths of a degree field of view in the 11. The Sun or the Moon just about fill
up the eyepiece on my 11 incher.
