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?

I see 15s when I punch in the FL and aperture, with a score of 183.

I'd be curious to know how it works out as I've very little idea of what the score really means photographically. I use a standardized formula so these score should be comparable across formats. So far my best results have been with the 15/1.7, I don't find the 8/1.8 picks up more stars but I've only gotten the fisheye out once for clear skies.
