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

I found 25s was a touch too long when pointed at the celestial equator, but gave decent results for Orion and good results for Polaris.

My spreadsheet numbers seem to be a reasonable max for the equatorial zone and can be uped as you point your field of view towards the poles.

I'm wanting to buy a tracking mount to use with my longer lenses for better spot details.
