Astrophotography

I have watched the sky since I can remember.  I made a 4" widefield reflecting telescope years ago out of a piece of PVC pipe.  I got the optics from the surplus room at Edmund Scientific which sadly does not exist anymore.  The room had bins of chipped lenses, prisms, mirrors, army surplus stuff:  buried treasure.  That telescope cost me about $10 to make.  I got years of skywatching out of it, but left the scope in Africa.

A few years ago, I made another 4" scope, but the only "mirror" I had was unsilvered.  Here it is on a alt-azimuth mount made from pipe fittings.

I used three spring-loaded bolts to adjust the mirror.  The little tube on the side is just a tube, to help line up the scope.  I chemically silvered the mirror using silver nitrate, sugar, and potassium hydroxide solutions, but the surface quickly tarnished.  I managed to get this picture of the moon with scope, using a digital camera:

With Mars so close in August 2003, I got the 8" Deep Space Hunter from Hardin Optical in Oregon.  It's a Newtonian reflector on a Dobsonian mount.  Here it is looking at Mars:

Mars showed me its polar ice cap and some surface detail on August 28, the best night for me in the hazy Jersey Summer.  I pointed my little digital camera into the eyepiece, got this featureless disk for Mars:

Here is a shot of the moon through the telescope:

Click on the picture below to see the thin crescent moon and a few of the seven sisters. I watched several stars wink out behind the moon as it slid across the star cluster.

Sky Pictures

Mmff-plff years ago, I made these pictures in the darkroom.  (It's much easier to do this now with the computer.)  Click on a thumbnail to see a bigger picture.

Andromeda over the bay:  wpe33.jpg (37578 bytes)    Enigmatic Galaxy over the highway:  wpe34.jpg (30692 bytes)

Here are some star pictures taken at about the same time.  I used a 35mm camera, 400ASA black and white film, 10 second exposure.
