If you were intending to use this battery supply source for only the LX90
and maybe a dew heater, one of the small jump start batteries would do well
(these are usually 17 AH batteries). However, the other stuff you wish to
power complicates things. If you absolutely need to power all this stuff in
the field, I would suggest 2 batteries...a small jump start battery for your
telescope and a marine deep cycle battery for the rest of the accessories.
You could buy both at a membership store such as Costco or Sams for $50
each. BTW, a power inverter simply changes DC current to AC.

I'm looking for a portable power source for my LX90 and imaging equip.
I am not an electronics buff, and I am confused by all the different
posts that I have seen regarding this. In addition to the scope, I
want to power a video camera, monitor, & VCR. What kind of portable
power supply do I need? Do I need to be concerned with amps, volts,
watts, wobbelators, kenuten valves? AND, where does a power inverter
fit in to all this? Do I need one of those too?

Thank you in advance.
