"perfect with my ONTC 12"

I´m using Maxfield CC with TS Photon 6" F/4 which I find to be quite good (and most importantly inexpensive) combo.
This CC does a good job correcting the coma, almost to the edge and with minimum vignetting on APS-C sized sensor. Unfortunately it seems to be introducing some Chromatic Aberration, especially noticeable with Narrow-Band filters. This is fixable in the post.
I would not hesitate to buy this CC again if I was looking for the compromise between performance and price.

"Funktioniert mit meinen Newton sehr gut."

"Fits perfectly, easy back focus with a M48 37.5mm spacer to M42 camera side connector. If you are imaging with an f/4 newt, you need a coma corrector. This one is reasonable price and good performance."

Great corrector. A lot less vignetting compared to the GPU. It is short and it does not protrude into the light path unlike the GPU.
