GM 8 power supply

Have you felt the need for the Losmandy regulated power supply for visual use or has a 12 power tank been all that you need? I will be using the scope for public star parties and the absence of long power cords is an advantage.

And yes, it'll be much more convenient.

What this means is that you can run it off of a small battery pack using rechargable AA batteries, or a small battery like used for home alarms and the mount will run all night.
So, unless you are running other equipment, the power tank is overkill.
My own experience with power tanks (I have had two) is that the batteries only seem to last a couple of years.
They are also bulky.
For my non-Go-To mounts, I usually prefer to run them off of small battteries or battery packs because they are far more compact, cheaper, and I can just recycle the batteries when they die rather than tossing the big power tank.

Or this. You can buy a small charger, and you can make a custom cable that just clips on: http://www.buy.com/p.../208713948.html

My GM8 has encoders installed. I have access to a Sky Commander which I want to try to see if I want a "push to" system.
Looks like I have no need for an expensive power supply!

A home alarm backup battery will run the scope for a long time.
Heck, I had a freind that used to run his Meade LX90 off of a home alarm backup battery. Would easily run the scope a couple of hours unless he was slewing.
Even my Meade LXD-750 only draws 400ma when ticking over. It is the slewing that sucks current.
One of the really nice things about mounts like the GM8 and C11.
I have often thought of going back to a Ci700 for my 6" APO. I had a DSC on it, and push to was fine for my use. Fast and Quiet. Mount would run for hours off of AA battery pack.
So, a battery pack will do you.

I also have used the Celestron 12V/7AH Powertank for visual use since 2003 and have never been let down at a star party. (But I finally did replace the Powertank's battery a year or two ago with an identically spec-'ed one from a local hobby shop, and it only cost $18.)
