Hi,

I am looking for a refractor with 200-250mm focal length. I wish to
capture the whole full moon/sun at prime focus with my ToUcam Pro
(eclipes video). I believe that I cannot cover the whole disk with
focal length beyond this.

Could you please advise where I can find such telescope; objective
size 40-50mm is OK.

I already have Televue Ranger; but I cannot find any 0.5x reducer for
it to serve my purpose.

Thank you in advance for your suggestion
Chote

Check out TeleVue's 60mm apo. But honestly at that focal length, any
decent achromat will produce good images.
