Quote:Thanks Mighty Kong!I think that my question still stands though. If an average performance in PE is + or - 4"to 7", then this mount does little (if anything) to warrant the extra cash out of the box. I should think that an Atlas, Sirius, or CGEM is capable of these numbers as well. Plus rebuilds if I recall, the hyper tuning jobs on the Atlas Mounts do not entail an expenditure of $500 for a part.This doubles the cost of the competitive offerings at this load bearing capability. Please correct me if I am wrong ,but is there something I am that missing? What other qualities are there that would justify this price? I don't mean to be confrontational, but really would like to know. Add on... I am in the market and haven't scratched the GM-8 from the option list. So, any help would be very useful. Thanks All!

Quote: Yes my budget is a bit too tight for the G-11. In fact the GM-8 Gemini would be a hard stretch, but if there is a clear advantage for AP over the Synta brands then I could push it to go the GM-8 Gemini. My load is a projected 20-25lbs with my WO98mm, WO66 guide scope, Orion autoguider, Canon 450d, and hardware. Is this asking too much of this mount?

Quote:EDIT: Like it or not, the reality is that the 32 bit OS is rapidly going the way of the dinosaur. I don't wish to start an XP vs. Vista scrap here. I just think that those companies that wish to keep selling computer driven equipment really have an obligation to keep there software workable.
Quote:What software would you be talking about? The G-11 or GM-8 work with a hand pad or you can use a computer with a program like Starry Night, but there is no software for a computer required to run the mount.
As for the 32 bit vs 63 bit, well there is not that much 64 bit software out there really. Maybe the OS is 64 bit, but the programs are mostly not.
Quote:Does this mean that I don't need drivers for the 2 components to talk to each other? That is not what I have been told.

Quote:Perhaps I am asking the wrong question then. Is there software out there that is compatible with my Vista 64 bit OS that is also compatible to remotely run the GM-8 mount? Is this what I need to ask? I am so totally lost with this issue. Please somebody set me straight!

Quote:In my experience, PE is much more important than you make it out to be. Remember, autoguiding corrects after the error occurs. If the error is not periodic and predictable, as in lesser quality mounts, then the error must be guided after the fact. It will show on the image prior to it being moved back to the correct position. This can reduce the sharpness of the image. This is the reason that a 20 arc second average mount is not nearly as desirable as a 10 arc second mount.
Quote:Perhaps the best thing to do is go to an EQ6/Atlas group and ask what sort of guiding times these people can manage. I think you'll find the Atlas, while a good, solid scope, isn't up to the standards of Losmandy, either the GM8 or the G11. But that's my opinion. For the most part, the error of the Losmandy 8 can be predictable and mapped iwth PemPro. And the Gemini can be purchased separately, although that will cost a few hundred more to go that route.
Quote:And finally, don't underestimate the quality of the new Ovision worm that can be purchased from France at a later date.
Quote:That raises another point. If someone were to purchase an ovision GM8 worm assembly, is it the same as the G11? I could see someone upgrading a GM8 with the expensive worm then putting the original back when they upgrade to a G11. If that's possible.
Quote:Just to clarify my last post. It is certainly possible to guide out error, whether periodic or not. But doing it after the fact often leaves evidence of the error. If you can see it in guiding, you can see it in the image.Theoretically and in practice, using PEC can guide out the periodic elements of the error as the error occurs. It's advantageous to do it this way rather than just having PEC turned off and correcting the problem after the fact.
