The lack of need for autoguiding is fundamental to their approach ... The stability and accuracy are engineered-in, obviating the need for "sophisticated" feedback loops [*]. Skip lightly down to the HPS Technology section on this page : **LINK**

Of course the irony is that guiding out errors in lesser mounts is just as effective in practice. As I recall unguided mounts need you to spend ages building a 'sky model' before you start imaging because it needs to be able to compensate for diffraction effects in the lower sky which can vary considerably from day to day. Nothing is that simple.

From someone who knows people who work at Greenwich:

"Main instrument is a C14, there is a Skywatcher 120mm f/7.5, the Takahashi FSQ-106 (which was donated), a 100mm Lunt H-Alpha scope, all riding on a Software Bisque Paramount ME II. "

Thanks, Neil ... I stand corrected. blush

From the video, the mount looked like a 10-Micron from a couple of years ago.

No astronomical equipment involved, but went to lock up the shed in the early hours of this morning and Mars was incredibly bright. Thought it was an aeroplane until I realised that it wasn't moving!
