It is suffering from a number of mechanical issues though. The triangular stars are caused by either a pinched primary or secondary mirror (probably primary), there is a LOT of field curvature which is either going to be caused by a spacing error of ~5mm or, on a 10" system, no RC flattener.
Considering that it is from iTelescope.net there isn't anything that you can do about that  I do have a bit of a gripe with iTelescope.net; for a company that has an entire business model around selling time on various telescopes, most of the data that I have seen come out of it has had issues in one form or another. Whether it be mechanical issues like above or stray light (light leaking into the optical systems) presumably caused by light being on in their facility. |
Thanks Colin. I dont always get that star trouble (apart from the corners), my fault. Also, the scope is mine, hosted and installed by me, not for hire, mechanical problems are all my fault and nothing to do with itelescope and yes it is a 10"RC with no flattener, im right on (or over) its chip size limit without a flattener and orthoginality is a bit off, the RC is pretty old.
Geez enough already
Ill try harder next time.
