Star Streak Tutorial
and mirror lock-up.
[Caveat: not all SR-T's which offered MLU when they were introduced had it near the end of the SR-T
series' production; for some reason Minolta started mucking around with the features each model
offered. You'll know the model you're looking at has MLU when you see the small circular switch on
the lens mount housing, above the DOF preview plunger and right next to the self-timer lever.]
For more information on SR-T's, visit the Minolta User's Group.

Next time you're shooting star trails, try this: Make your long exposure at a small aperture, then open
up the aperture for another five minutes. You'll get a star at the end of the trail, and be able to make out
constellations. I like to hang my hat on the camera for a few minutes in between exposures to make a
slight gap.
Another idea is defocussing. Start the exposure with lens at infinity. Then, every so often (1 hour, say,
on an all nighter), just barely twist the lens the other way, like so (that was obviously few minutes long
at most, but you get the idea). You'll end up with a rather unique photo, heck, combine defocus with
Roger's idea!

This page provided me with information, which after significant trial and error, resulted in this picture:
Aurora Australis and Star Trails at Cradle Mountain The additional element of the aurora light
contributed nicely to the picture. I can recommend f5.6 to f8 for Provia 100F.
