Visit Show room, pick-up items...

Good process, to bad you will be moving and not have a show room... Hope your new place in Carlsbad works...I know it is overhead, but would be nice to have a small showroom where we can come and see you from time to time...

Stop the flop! Mirror stabilizers that work

Anyone that has done imaging with the large C14 knows how troublesome the moving primary mirror can be. Tracking within 1” accuracy will show the slightest movement in the primary mirror when it flops on the baffle tube. Even a fraction of a millimeter is noticeable. The Zapsteel Flop Stoppers utilize the same mechanical design that are in the EdgeHD locks and while they don’t completely eliminate mirror flops it will make it much more tolerant. Mind you the Flop Stoppers will do nothing to eliminate focus shift but if you lock down the mirror and use a crayford on the rear cell you’ll find that to be a useable setup. For Hyperstar imaging that cannot use an OAG these are essential for the C14.
