ASTRO: Nikon D200 First Light

Here (http://www.kopernik.org/images/archive/sagittarius.avi) is a
'movie' made from a small number of 30 second exposures I made with a
borrowed Canon Rebel DSRL (no mod, so very little red sensitivity) mounted
on an Orion EQ-1. The lens was a Tamaron 28-210mm zoom working around 35mm
and F/4. This is a big file, so if you are on dial-up forget it!

The EQ-1 is Orion's smallest mount and I got a "second", mostly for use
with my solar PST, but it works great for wide-field tracking. If you get
into this DSLR astro-imaging I suggest getting a free copy of IRIS and
read
the tutorials, etc. It's a difficult software package to learn, but it's
very comprehensive, and best of all it's free!!

BTW, this 'movie' was made with the nearly full moon up!! Subtracting
out
moonlight is one of the benefits of digital.

Clear skies,

That was a neat movie! I saved this info for future use. Thanks George,

Scott

I would like to get a small tracking mount for the camera with a telephoto
lens and guidescope. Haven't really looked into that yet. I'm still
getting
geared up
for my daytime photography. The D200 has an intervalometer feature as
well.

I'm going to title my next effort "Attack of the Killer Tomatoes II", or
"The Moon eats a Deep Sky Guy".
