Peter the using of a 600w inverter is a very inefficient way of powering it all it won't take too long to kill an 85Ah battery with a 600w inverter, it's overkill for what you're powering. I would of gone down the DC to DC route a far more efficient means.
BTW the Full River AGM is an intelligent buy, one of the best AGM's out there. Deep Cycle batteries aren't all equal.

I have bought a new Full River 85amphr/20hrs deep cycle battery and a Jaycar 600w full Sine wave inverter. This will power the LX200, The Starlight camera and my Toshiba laptop. The dew zappers will run directly 12v from a 55 amphr battery.
Can someone confirm that the LX200 will use about 1amphr (doing say 300+multiple short slews). The SXVHR9 is rated at 1amphr or less and the lappy about 6.5 amphr. So over say 7 hours that would be 8.5amp draw per hour so I should get a night out of it without draining the battery too low. Then when I get home within a few days fully recharge the battery and this will prolong its service life.
Thanks
