That looks very tempting Peter. What is the age and condition? Does it include the 2" to 1.25" adaptor? I think I could use it on an old fashioned f15 refractor. I know D & G use this model on their achromatic refractors and 20" cassegrain.
Yes includes a 2" to 1.25 reducer. Sorry no 10:1 Age? does it matter? Current models are identical. Best guess 4 years. Like all AP stuff the action is delightfully smooth and precise.
The picture does not show the RCOS plate (has 6 holes to bolt to their RC's)
