You're right Mike... on all three counts.
Finding someone to carry out the first 2 is particularly troublesome if not impossible and the third? Nigh on impossible if you're dealing with anyone remotely connected to the product (ie where you bought it from, dealers etc).
Thanks for that link John, although from my initial reading of that page it looks like it's intended for assessing the "figure" of the optical components and not their alignment/ orientation???
I fear the problem with my scope is the corrector has rotated/moved out of alignment.
Could be a worthwhile investment though.
I'm just about at the point of giving up, to be honest.
No-one seems willing or capable of testing and/or offering a guarantee it will be ok, even if the problem is correctable.
I could go into more detail but that would just depress me more, and I'd need to pass negative comment on a few astro industry "sacred cows".
I just don't need the grief
Bottom line (for me, anyway)... unless you can get a replacement, you are on your own kid.
