With the default PHD settings, a Lodestar guiding with a beamsplitter (similar to your ONAG) with the C11 @f10 and the NEQ6pro mount I can easily hold the target star on a 25 micron slit for > 10mins....

Hi Ken,
I've not done too many images yet, but I should add that I'm using a 2x barlow on the TEC140, so close to f15 (around 2,000 mm). Some of the images look ok, others show elongation.
But, can you help me with the original question? If two different scope/camera combinations yield essentially the same guide camera resolution should one expect to be able to achieve the same guiding accuracy? Would there be any other factor making guiding through my TEC140 so much harder?
Thanks,
Peter
