Fred,
First thank you – actually Don at Bintel mentioned your set-up (not the Paramount) the G11 to me today and the approach you took as an excellent example of how it can be achieved.
He was also quick to point out OAG is great – if and only if you can find a star in your field of view – given you are on the periphery of the light path from your main imaging target.
The big step forward for me is that as of today I have a diagnosis I can work with to improve imaging. Before this I had six or seven suspects to consider. Now its basically see if I can solve a rigidity (and/or a remaining balance problem).
Balance I can do very shortly- weather independent. Rigidity will need some experimentation!
I would be interested to hear if any users of OAGers with large SCT’s find it difficult to find a guider star with this kind of a set up. I had assumed the OAG would still see the same subject that the main CCD sees. But according to Don – this is not the case.
