You see, I consider that a short focal length (relatively speaking). So I still stand by my recommendation that the cost of the Ovision worm gear be budgeted for if somebody plans to buy a G11 for imaging.

from what i see a significant fraction of people doing AP, do so with refractors.

I'd say most people actually use 8" Meade or Celestron SCTs

Edit: That's besides the point. If for a $500 + shiping increase in the price of the price you can improve the PE of the mount 1/4 the original PE with minimal effort from the user, why not. We spend $500 on far less useful imaging accessories.

Hilmi,

I agree. 500 bucks to most of us is alot of money but we do spend as much as that on things like AO or an OAG.

Your results are awesome .

the thing is, i believe there is something wrong with the recent batch of G11s. 30" pk-pk is way out of spec historically speaking.

to be honest the absolute value of the PE is not really a problem. what's a problem are spots in the worm that have a slope too great to be corrected by autoguiding, which is what got me.

Rob,

There does seem to be a rash of 'bad' stories lately. I wonder what changed.

My G11, bought in 2009, had 8" peak to peak (stock worm). Never upgraded to Ovision or the new worm Losmandy offered either.

Gearboxes are in. I've got to fly to Abu Dhabi for work tonight, so I doubt I will get the modification done before the Thursday. How unfortunate. I was looking forward to getting this done tonight.

RS components delivered the gearbox, and the motor pinion gear has a smaller hole than what was mentioned in the specs. I don't have the correct tools to ream it to size since the hand 1/8" hand reamer I purchased wont go through the hole, it's too tight of a fit.
