Quote: Is the current version of the G11 still loaded with potential for erratic PE and racey stepper motors?
Quote:There's also mention of replacing the worms with hi-precision ones. <snipped>Have any of these issues been corrected by Losmandy such that the current version needs less modification than previous ones?
Quote:If my budget were larger this thread would be unnecessary. I'd buy an AP Mach1 GTO and be set. The G11 is just barely within my reach though, so I'm trying to inform myself of what I would actually be getting for my $3500.

Quote:Personally, I steered toward the G-11 on the basis of needing to maintain the mount over time. When I looked at the CGE and G-11 it seemed to me that the G-11 looked much easier to take apart and adjust than the CGE. Losmandy also sells pretty much every part on the mount as a "spare", too. I really like that - if anything breaks I should be able to fix it pretty easily.
Quote:I really liked my Atlas, but it wasn't the easiest mount to work on, and it I was never able to get replacement OEM parts for the internals, which annoyed me to no end. This was a major "tipping point" in my decision to get a new mount and I think that the G-11 will be much easier on me in this regard.
Quote:IF you are really set on sticking to your stated preference to not tune or swap parts in order to get the performance you seem to want - after shelling out for the mount, then you need to keep saving for another, more appropriately designed mount system.

Quote:2. that there's a PE spike of some magnitude that comes around every 76 seconds
Quote:This may seem like a petty detail, but how is the polar scope on the G11?
One thing that irks me about my Atlas (and my CG-5 ASGT before that) is the clumsy polar-scope adjustment screws. I have yet to really dial in the polar-scope on my Atlas despite all my efforts. Last week I dissected it and realized I could probably machine a kit that would replace some of the parts and result in a centered crosshairs that never move or need to be adjusted.
Just curious about how the G11's polar-scope stacks up.
Quote:What I don't like about it - the illuminator is external, the battery case is very clunky and does not come with a dimmer. I have taken to shining a red flashlight down the illumiator hole rather than using it. That really is my only complaint with it.

Quote:Have you considered a Tak EM200? Excellent tracking and painless polar alignment from all accounts. There's fantastic work being done with them and I've seen some complete systems for not much more than your budget.
Quote:You'll rarely see a used 200 for less than $4000. The payload is considerably less than the 11 and GoTo will rely on planetarium software.

Quote:I would be very surprised, however, if any of the software you mentioned does not work with it.
Quote:Ok Mike, you've peaked my curiosity. I'll look into it. I'm assuming that the EM200 will natively interface with MaximDL, The Sky 6, etc?I might be willing to go $4K if it doesn't need tuning
Quote:...and run Polar Align Correction and you will get VERY close.Blueman
Quote:The EM can probably get as close as the G11 after the routine Floyd speaks of.
Quote:The polar scope doesn't need adjustment...
