Doesn't look like a Comet Catcher to me, especially with an f/8 focal ratio.

My thoughts exactly. Not a true wide-field instrument. Even with the 1.25" focuser (as opposed to the .965" typical of these types of scopes), the TFOV is not exactly *comet* sized.

How good are the optics on these? Do these have the same integrated barlow unit that adds to the focal length?

Regards,

MikeG

I agree that this does not look like a Comet Catcher. I believe the Comet Catcher came with a "sliding secondary" focuser, not a regular rack and pinion type. It also was a schmidt-newtonian in design with a shorter system focal length.

Yup, the listing is for a "Comet Catcher Jr."
Really not related at all to the original Comet Catcher, except for the short tube and Celestron name.
