不知道Faster結構(CCD相机在鏡前),如何在遙遠控制中又鎖鏡(防止SCT mirror flop),又可以用馬達自動对焦(人不在鏡旁,不能先对焦后鎖鏡)?

Mirror God,

I must visit and see the ServoCat motors' mounting plates in real-life action, to gain some insights of the mounting possibility.

Dear Mirror God, Would the Servo Cat Junior version be even fitted to az-alt mount such as T-Rex mount (capable of supporting 20kg OTA and which has built-in digit setting circles for AN, as shown in the picture) ? A separate set of Junior motors would enable the ServoCat controller (capable of stor...

Very good as super sensitive wide field finder.

Not sure whether there is any low pass filter. Better to modify to remove loss pass filler and to cool it to reduce the serious chromatic noises.

Borg/Hutech also has a M57 outer thread filter ring system for M52 filter. With a thread converter adapter, you can convert M52 to M48 for astro filter.

The light path is about 15mm.

A bit slow to change filters for RGBLHa for 1 night but LPS type constant filter should be ok.
