You can't use it for imaging - that's a very BIG NEGATIVE cf Baader's and the now no longer made Lumicon 48mm Coma Correctors.
I read somewhere that it also is not a TRUE 2" (or 48mm) optic. Another NEGATIVE.
It also lengthens the focal length a bit unlike Baader's (or Lumicon's). I think that is a negative , but you might like that.
Having to buy two separate Paracorrs , one for use visually and the other for imaging, is IN MY VIEW a rip off !!! See the prices of these things (here).
And the tuneable top is a just gimmick designed to coax you to buy TeleView eyepieces.
Have you considered a Baader MFCC. |
You're right Ian,
I would also consider the Baader MPCC over the Paracorr. Can be used for visual and photographic purposes with no focal length alteration and still achieve a nice flat field.
