The Mewlon IS a Classical DK Cassegrain. I will probably get a Feathertouch after-market focuser for it anyway.... Set the mirror in one spot and leave it..
A FT focuser was my solution to the image shift problem. As I remember the 210 seemed to take about an hour to cool, which is about the same as the 8” Portaball I used at the same site.
The finder that comes with the 210 is the best straight through optical finder I have used. It’s sturdy enough to double as a handle, and there’s an optional attachment that illuminates the cross hairs.
I bought the 210 new. It arrived well collimated, and it didn’t need to be recollimated in the 2-3 years that I owned it. It’s a stubby scope, and mounted on the DM6, I needed to use the optional DM6 handle steer it.
