I was planning to purchase the Celestron focus motor (94155-A) to use with my Celestron  EdgeHD 11, which is mounted on a Losmandy G11 / Gemini-2.

My question is, how can this focuser be controlled for visual observing?

 

 

Thanks.

That focuser can be connected to a PC with USB A-B cable running the Celestron focuser app.  12VDC may also be needed if your USB port has low power.  If you use a USB hub for imaging, be sure the imaging camera(s) are on a different hub, else the focuser can glitch.

I was just posting about this very topic earlier today, and mentioned I plan to construct a diy hand controller for my Celestron focus motor (used with edge hd8 on zwo AM5 mount). following excellent work by mlord. (https://www.cloudyni...4#entry12177715)

 

In the meantime, I've been using a miniPC to control the focuser, as cinenosin said (although I use the USB Hub in my ASI294MCp for both imaging and focus motor and guide scope and have not seen any glitching of any of the items.). I connect to miniPC using an iPad to remote in to change the focus position. obviously will be better to get the hand controller thing working

Thanks for the inputs. I know this focuser is a great leap forward for imaging, but it also seems to be at least a few steps back for visual use. I can't understand why Celestron has not offered a solution, eve if it is with an accessory controller.
