Does anyone have the length of this corrector?  It has the lettering "F4/5 Coma Corrector Used on Reflectors" around the M48 end.

 

Or can anyone tell me if this is the same as the TS-Optics NEWTONIAN Coma Corrector 0.95x Maxfield - 3-element - 2" connection that TS recommends for their 6" F5 Newtonian?

 

Thanks,

 

David

It’s 2 inche in diameter and measures 3 3/4 inches to the flange, which would be the insertion distance.  The threads on the other side, which is pretty short, looks to be 46mm.

I have the SW Quattro F4 CC, and it is a 4 element design, not 3.  TS does sell a version of the same unit, but it is not the one you are referring to, it's this one:

That looks identical to mine, except I didn’t try to unscrew the flange.
