BAADER MPCC MK III 2" NEWTONIAN COMA CORRECTOR

Perfect. Just what I needed for my SW 200pds. Has the same back focus as I'm set up for already.

Coma corrector in a 10" Newtonian

The guy who sold me the telescope so many years ago said something about "when you get serious you will need a coma corrector" That was a long time ago and when i started taking astro images I found out exactly wheat he meant. The Baader has fixed all the issues I was having. You do have to be careful with the distance between the CCD and the Coma corrector but that's not a big deal, just read the instructions... I needed the Baader due to not wanting to make my rig any longer from the focuser than I had to. I'm aware there are other brands but i cannot comment on them. All I know is that now all my stars are sweet and round. :-)
