Hi Mark,
I have the same SN10 scope as you are selling and found that I needed an EQ6 to use it for imaging. I was wondering what you were going to do with the damaged mount. I live in Adelaide and I coordinate the Astro-imaging Group for the Astronomical Society of South Australia. We regularly hold camps in the Flinders Ranges where we teach newcomers to the hobby basic Astro-imaging. We are always short of Equatorial Mounts for teaching Polar Alignment and widefield imaging. If you are going to dispose of it please let me know.
Thanks for your consideration.
Cheers,
Jeff Lusher
