Power Supply

I got a Starfinder mount, and found that it only takes 6 AA
batteries, but im thinking that 6 brand new batteries wouldnt last
very long in powering the mount. Can anyone tell me how long the
power would last with 6aa batteries? I also have a battery pack from
my LXD55 mount witch takes 4 D batteries, and i was wondering would
that over power the mount and fry it? Any info would help.

Thanks
Matt

D and AA and any other type of standard single cell batteries put out between 1.2-1.5V. 4 D batteries may have a higher capacity than 6 AA's, but won't damage a mount intended to use 4 D's because they produce a lower voltage. In fact, you may find that the mount is underpowered and that it won't function completely, assuming that the batteries are in series in both mounts (a safe assumption).

I can tell you that my Starguide GoTo mount (Tasco/Celestron) will last about 8 hours on 8 AA NiMH batteries with 1800mAh capacities (that's a total of 1800mAh charge since all the batteries are in series) when used normally - tracking, slewing, etc. It's a much smaller mount and scope than yours and 1800mAh is around double the capacity of a typical alkaline battery. I seriously doubt Meade's claim of 50 hours on AA's with the Starfinder has any merit at all.
