However, I'll add my experience - I got perfect stars with 25 second exposure, 12 mm (24 mm EFL), f2.8.

Thanks- was this with Orion and pinpoint stars even when viewing 1:1?

I've not shot when Orion was up but no trails at all.

Thanks, I viewed your spreadsheet and came up with the following: 8 seconds at 14mm focal length (28mm equivalent) should be enough to achieve pinpoint stars.  Have you found the same?
