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

Paul Sterngold wrote: I sum integrations, but as far as the polar alignment goes, it is the same as a continuous exposure. I typically do 60 to 90 minute shots. Here is a 90 minute shot at 1375mm

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

I can comment on #4, as I have a C9.25 that I use on both a GM8 and a GM100 (predecessor to the G11). IMO, the GM8 is enough mount for visual use but not for photography or imaging through the

I am going to purchase an SCT but am undecided on a GEM or a fork mount. Under consideration are: C8 Deluxe, LX 200, U2K and C 9.25 on a GM 8. Any information you could offer on the following would

Thanks Rockett and Paul for the feedback. I was afraid there was a problem and you guys confirmed it. The cables are all plugged in correctly (that was the first thing I checked). I called Pocono

Rockett, I'm sorry but I cant explain my argument better, lead acid batteries have a finite number of times that they can be discharged to zero, also they don't suffer from a "memory effect". I really

No, this is not normal. You have a defective hand controller. Rockett Crawford Tony Bonanno wrote:

Hi Everyone, Just received my new GM-8 yesterday and my initial impressions are very positive. I had never seen one before and purchased it on its reputation. I think I've made a good choice.
