Here is a better one of Cassiopeia, showing slight star blur due to the long
exposure. I think you'll recognize a few things in there.

That little 'hook' on the upper left of ea. star is lack of cable release,
methinks ... MLU not needed for such long shots.

You also caught Andromeda in the

suck out there! ;-| 2 million light years away... did you use the better beamer?)


Btw, what is a good low-cost tracking device that I can use to track the stars
with my DSLR?

http://hardinoptical.com/8lx200gps.html is low cost (snicker) but I don't think
AF or AE will work on your camera.

It always amazes me how fast the damn stars move (okay, it's us, but,
whatever) that would streak at 30secs but we can't see it with the
naked eye...

Well, that's about .002 degrees, or .125 minutes of arc......

Yes, that's why I posted that one for Michael. There is also at least one
meteor streak.

No, just the pop-up flash.

And it's quite a slow lens. I'd have thought an A-P 400GTO would be
more Anni's style.

How about an untra low noise 1 pixel camera...

That is called a photomultiplier tube, and we measure star brightnesses with
them. Really.

I've heard of them. How do you ensure light from only one star is hitting
it?
