Hey guys, yeah thats an idea as I have a Sigma 50mm f/1.4 lens. What would be the max exposure length possible on a standard tripod with a 50mm at f/2.2 - f/2.8? 10 seconds? Probably would end up with a similar amount of light on the chip in that time as it would with a f/4.5 lens for a 30 second exposure.
I'll try this too next time Im under a dark sky. Just need the clouds to disappear.
