Maybe I can help you with your power concerns and the 8" LX200GPS. On another users group dedicated to the GPS version of scope, virtually no one uses the internal batteries. The scope responds best to a voltage of 13.6 to 15 when slewing and working with a load. The 8 C cell batteries at most will only put out 12 volts, add cold weather, and it will be less. Don't get me wrong , the internal batteries will work, but the amount of time they will work makes them a very expensive way to operate the scope- in the field.
Most owners, including myself, use a 12v. 26 Amp Hr. Jumpstart Battery. They typically put out 13.5 volts fully charged and will run the LX200GPS 8" several nights before charging is needed. I use this battery even though A/C power is available. I don't have to worry about the power company interrupting my viewing session or surges or power spikes or electrocution. However, do not run any dew equipment from the same battery source.
Editors note: for additional battery power ideas see this topic.
I have two Jumpstart batteries, one for the scope and one for the accessories. Also do not try and use rechargeable C cell batteries, their power curve is horrible for use in this scope especially in cold temps. Many have reported using these Jumpstart batteries for over three years on various scopes, and they still take a charge fine.
We use the battery compartments to hold counter weights to balance the scope in polar mounted (wedge) situations. Remember, if you feed your scope the proper diet ( 13.6v to 15v. ) to keep it happy.
