Milky Way in Scorpius

Nice one, Pete. Was this tracked manually?

Yes, Michael. About 8 minutes, through my 6" Newtonian.

The 28mm wide angle was always very forgiving. Polar alignment was more important than any (manual) tracking errors...

Thanks, Pete. I'll have to get a shot like that one day, just to say I've done it. Problem is dark skies (or lack of) and that I'll have to stack multiple short exposures, although I have never tried 10(ish) minute exposures on a dSLR,

Check this out, Pete, and the homepage for more time-lapse and .gif:

Michael, I got a tremendous amount of enjoyment from the link to Josh Walawender's site!

There was so much of interest going on in the Mauna Loa time-lapse, that moved me to download the 175 Mb high res. version...

Apart from all the action in the foreground, the moving cloud cover and the distant speeding traffic, I was most enthralled by the circumpolar motion of a few old familiar constellations - Cassiopeia and Perseus in particular.

Cheers,
