I would really love a Tak 106ed but I'm not willing to wait at least 8 months. It seems the Sharpstar 121mm f/5.6 ED Quintuplet is available now. I can't find much info about this scope and would like to use it for astro imaging with a GFX100 and Sony A7R4, mostly nebula. Any thoughts?
I will also need to purchase a mount. Do you think the EQ6 would be a good choice? I could budget up $3k for the mount.
The EQ6-R is a fine mount, the latest version of the much beloved Atlas.
It also weighs a lot. A mount with very similar performance at half the weight is the iOptron CEM40 or GEM45 (variations on a theme).
But all those are $1600-$2000. Mount price is an excellent guide to quality, this market is quite efficient.
The $2550 CEM 70 is significantly better. Intermediate in weight. So too the $2900 Losmandy GM811G. I'd recommend one of the last two. The mount is the most important part of your setup. There is no such thing as "too good" a mount. Better mounts make everything work better.
But, all of them are hard to find right now. Supply issues and a boom in people wanting to do astrophotography.
