I go thru one or two large marine batteries in a year, I fly electric powered RC planes (24 nicad cells, 30amp currents), plus I have a bass boat and then telescopes with a large amount of dew heaters

Very nice!, very high resolution, you can see an eagle within an eagle, both of them diving to the 4:00 position. Take a look at mine: http://home.att.net/~hermperez/m1671599.htm Herm Paul

If you rotate the images prior to stacking, then you can cancel out field rotation (obviously some of the rotation, not all)...in other words, you do x-y adjustments on your images to stack, but if

Me too, but after I tweaked the polar alignment scope. A friend does one star DSC alignments after using the polar scope. Do a precise drift alignment and then check how far off your polar scope

Thought some of you might be interested in hearing what the problem with the hand controller actually turned out to be. The hand controller board was wired correctly, BUT when someone attached the

Nice image of the Eagle Neb, Rockett. See my LRGB image of the same subject at: http://members.home.com/jsterngold/lassen2000/june-astro-images Taken with an SXP MX916 CCD camera through a 6" f/8

My (actually, soon to be mine) polar scope also inserts through the polar axis. There's no set screw that I've spotted yet. You just insert the polar scope into the polar axis of the mount and screw

How long are you able to go in a single exposure without trailing? Paul --- Rockett Crawford <Rockett@...> wrote: __________________________________________________ Do You Yahoo!? Yahoo!

This has been my experience with my one year old G11 too. I have stopped drifting even for photography. Pete alignment necessary. place --

Sorry to respond to my own post, but I wanted to add that the G-11 polar alignment scope is mounted directly through the polar axis of the mount. Rockett Crawford

How long are your exposures? The polar alignment scope on my older GM100 attaches to the side of the RA housing and is woefully inaccurate. I have to drift for nearly an hour to get accurate

Hi Rockett, From personal experience and some knowledge of the subject I will have to Agree with you! IMHO the life reduction from repetitive discharging and recharging has a far greater effect on

Hi Gregory, Thanks for replying. The previous owner of the mount is of the opinion that the polar finder will get me close enough to use the DSCs with only a 1-star alignment. Do you agree? I'm

Ray, You should be able to turn the polar finder without releasing the locking ring. The polar finder may be stuck from old grease?? You can't use the DSC's in alt-az mode on a GEM. You CAN use

George, Define your purposes first. Are just into the visual targeting or do you plan anything like imaging, photometry or astrometry? GEM's make excellent platforms for the above but is unecessary
