mirror locks for a C-14

 

Good Morning,
?
I have a 10 year old Celestron C-14 SCT that I have recently mounted on a Software Bisque mount for the purposes of high resolution imaging of the moon and planets, using a Skyris camera, and CCD imaging of Deep Sky Objects.
?
I am in need of a way to lock down the mirror to prevent image shift during image acquisition.
?
I’d greatly appreciate any suggestions as to where to purchase an accessory that will enable me to lock down the mirror after focusing.
?
Thanks very much in advance.

Software Bisque used to make a locking collar, maybe hard to find now:

One of my C-14's has a locking collar that I installed when I switched to a carbon fiber tube.? The locking collar helped main mirror stability somewhat, but I still liked the flop stoppers better.? The carbon fiber tube is terrific; the focus stability improved a great deal to the point where in the summer with no more than ten degrees F. temperature change, the focus did not change at all.? I would recommend the flop stoppers alone--my two cents worth.

C14 has mirror flop?
 

most certainly.?

Though the "Edge"? OTAs contain pre-installed mirror locks.
 

My solution with C14 mirror flop in both Hyperstar and cassigrain mode?was to replace the stock moving mirror focuser with a focuser that has no mirror flop. BTW ?no mirror locks are?needed with this new focuser. In addition collimation of the primary/focuser assembly is from the rear on the outside.??
