Planet X. Well, that or a UFO anyway. Nothing else is possible at all! :^)

Power Supply

Posted By Dan Goldberg

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.

Mars (bugger)

Posted By Dan Goldberg

See in Vancouver, here in Canada, I have a scope but it doesn't get dark until around 1AM (after which it gets light again at around 2AM) and Mars is barely over the horizon smile

So when people say "Mars", I say huh?

New CG-5 Mount

Posted By Dan Goldberg

It's still just a CG-5 (EQ-4) available with or without GoTo. I don't think that anything has been done to upgrade it from a mechanical standpoint. If you've got a CG-5 then buying a newer one could not be considered an upgrade except if your old one has degraded to the point that it's unusable smile

Might be worth pocketing the money and getting an HEQ-5 or EQ-6 at some later date. As far as Synta goes those two mounts are as good as it gets, and they are even highly regarded as far as any mount goes (particularly in light of their price tags).

Speaking of Mars..... Uhhhh Ohhhh!

Posted By Dan Goldberg

Haha, come on. That would be hilarious. (Irony)^n

I'm not going to be able to see much from my location anyway so I might as well laugh smile

Were you using an appropriate filter or just stumbling around blind afterwards? smile

At least you didn't take any equipment out with you, right?
