Hi Chuck, You may want to look into the new Celestron EdgeHD 8" OTA. It's an aplanatic SCT so it should have a nice flat field with no coma. Here is a link to it at OPT. http://www.optcorp.com/product.aspx?pid=1-600-602-1544-13267 Clear skies, Dale.

Trying to choose between a 7" f/15 Mak and 8" f/10 SCT for the CGEM.
Bear two things in mind...I've always wanted a Mak and think it a better choice for my usual suburban viewing of "round stuff", double stars and clusters, while still being fairly good for deep-sky from dark sites.
Secondly, I will probably spring for a C-11 OTA sometime in the next six months, so an 8" SCT OTA would get sold when that happens, while I would keep the Mak.
Opinions sought. Help Chuck spend his money before the soon-to-be-ex wife gets it.
Thanks!
