I am starting to use the mount for some autoguiding and figure it will burn through batteries even faster than before. I found a 6V 1A ac adapter in hopes to use for powering the drives, but when I checked the output of the adapter (without any load) it is reading around 8.8V. I am wary of hooking it up right now to see if it will work in fear of burning the motors out....Would it be OK to hook it up even though it is reading 8.8V? or would the voltage drop a bit when connecting it to the motor and be in the 6V range? -------------------- Celestron C6-N 150mm f/5 Newt Meade 70AZ-Z Post Extras:       GeorgeDuke Pooh-Bah Reged: 04/24/03 Posts: 1142 Loc: PARADISE!

As soon as you put the motor load on it will drop. If you check a 12V car battery it reads 13.8V until it has a load. -------------------- George -------------- LX200GPS 203mm f10 StellarVue SV102ED2 Feathertouch Ser#0018 Celestron 130mm f15.4 Mak LXD75 GOTO with Orion 16" pier extension Desert Sky DSV1 dual head ALT-AZ mount Baader Hyperion 8mm ,13mm, 21mm and 8-24mm Zoom 2" GSO ED barlow, Orion 2" Prism Diag. 2" WO Dielectric Chinese Scopes, Chinese Eyepieces, Chinese Wife, Love them all!

I hooked it up to my hand controller and it seemed to work fine. Now if I can keep those pesky clouds away... -------------------- Celestron C6-N 150mm f/5 Newt Meade 70AZ-Z Post Extras:       Pages: 1 Previous   Index   Next   Threaded   Extra information 11 registered and 9 anonymous users are browsing this forum.
