Several Meade 10" S/N scopes have been sold on Astromart this year, one as recently as last week. Note that this OTA weighs approx. 45 pounds. It's a beast!
No, an SN-10 is closer to 23 lbs. I have one and my CGEM easily handles it.
In terms of weight and balance, the corrector places the COG nicely near the middle of the tube, unlike a standard Newt that is primary-end heavy, with the eyepiece high above the saddle.
The Schmidt corrector fixes much, but not all, of the coma. For visual use, that’s usually adequate correction for moderately wide FOVs.
For AP a Baader MPCCIII corrects the coma for a full-frame sensor, but works best at a 49 mm flange distance instead of (the typical) 55 mm. If you have an APS-C or smaller sensor, you probably won’t need a coma corrector.
As with any Schmidt corrector it will collect dew. There are Dew-Not straps and Astro-Zap shields that fit the SN-10.
