Any good Refractor focal length 200-250mm for ToUcam Pro?

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

One method is to use a 35 mm camera lens. Not sure what sort of mount you have
with your ToUcam 200mm lenses are available relatively cheaply and probably
more than adequate. I use old Minolta stuff with an adapter from the Minolta
mount to a C-mount and then a C-mount adapter which fits the camera.

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

50mm finders and binoculars would be about this focal length.
Check www.telescope.com They may have what you need.
