Thanks, Alexander, Carlton, Chris, Leon, and Martin.

I took this after an evening of trying to sort out a tracking problem, turned out it was the camera not tightened up sufficiently on the upper ball joint.

It wasn't late Martin, between 9.20pm and 10.20pm, we're three hours
behind the Eastern states.

This was chosen to take up Alexander's suggestion in another thread.
I will try again tonight at 250mm which is the longest lens I have, but
the subs will be shorter due to my so-so polar alignment, and the tracking
limitations of my little Nano Tracker.

Incidentally, all my work is JPEGs, no separate darks, flats, or biases, and
all [very basic] processing done in DSS, except for a little bit of sharpening done in Irfanview.

To my mind this shows that reasonable results can be obtained with
basic gear if one is budget constrained. Just simple tripod, DSLR and lens[es] and a Sightron Nano Tracker or similar. Outlay $60 tripod,
$250 used DSLR and kit lens, around $275-300 for new tracker =approx. $600. Some people will of course already have a tripod and
camera, and just need a tracker.
