Hi guys,
What is everyone using to run your laptop, SBIG camera, and mount at your remote sites?
Equipment:
ST8E camera
Dell Latitude D610 laptop
Losmandy G11 mount (non go-to)
I'm trying to figure out whether to purchase a 400w power inverter to run my laptop and ST8 off AC from the same 12V marine battery that runs the G11 or get dedicated DC cables for them (expensive!!). What combination will get the best battery life? I think my battery is rated at 95ah. The laptop AC adapter says 1.5a @ 110v and the AC adapter for the camera says 43w @ 115v, not sure what the mount needs. Some online power calculators seem to indicate only 3-4 hours of operation time, which seems awfully low.
Thanks,
Robert
I use a deep cycle marine battery (aka trolling motor battery) and an inverter. I tried a DC - DC converter for the laptop, but it couldn't handle my guide camera, which is a DSI, which uses a lot of power off the USB bus. It will work intermittently with the ST2000...it worked OK till I upgraded the laptop memory (a big, honkin' 3.2 ghz Toshiba). I think my main problem is the PC, not the ST2000 and its Peltier. Eventually, I'll get smart and get a netbook. Anyhoo, with inverter and big battery, I can go as long as I want, though not all night.
The scope (either a NexStar 11 or an Atlas mount) runs off its own separate jumpstart battery.
