That’s a nice setup Dave, WOW!!
my Meade is the LX200 without the mirror lock but I don’t have any mirror slop issues really. I have a crayford refractor type focuser on the back which works very well for fine focus as the main Meade scope focus can be tricky sometimes, I get the scope focussed best I can then use the crayford to fine focus, works fine for visual, I will see how it does when I get my 6D back from being Astro modified and see how I get on with that focus setup on the next clear night we have.
so I’m guessing your guiding okay with the refractor, no guide slew issues with longish exposures?
Your setup is great, is that the 10” scope or 12” I would love to see some DSO snaps from that setup if you have any?
