Great thread and input from everyone. Very timely for me.
I'll be heading out to Leyburn again each month after several years hiatus. I have equipped myself with a 2nd 12inch LX200, spare SXVHR9 and all the other bits I needed to do my SN search once a month from there - ok an extravagance, but like government policy why pay for one when for twice the price you can have 2, at least that way the home observatory stays intact.
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
