My interest in astronomy began at a very young
age, but I didn't get very serious until I started college four years ago. A friend had a junky K-mart style
refractor and we saw Saturn, Jupiter and even a few of the brighter Messier
objects. Once I started making
enough money to purchase a telescope, I bought a 12.5" Meade Starfinder in October of 2002. Since then I have observed all planets
but Pluto, all Messier objects, all objects on the Herschel 400 list and many
Herschel 2 objects. I started in
astrophotography several months after buying the telescope. Since my telescope didn't come with a
mount, I was only able to take very short exposures. Moreover, I only had a digital camera
that only did short exposures. I
started with lunar and planetary photos obtained by sticking the camera up to
the eyepiece. I then purchased a
Logitech Quickcam Zoom and learned about a process
called "Off-Chip Video Integration." Here you stack thousands of individual
short exposures hoping to get images of dimmer objects. This turned out to be nearly impossible
for most deep sky objects. Most of
the photos I took with this camera were planetary. Then I learned that some webcams can be modified for long exposure. The first one I obtained was a Connectix Greyscale. You simply snip a wire on the inside and
you can now take long exposures.
The problem then becomes that Dobsonians can
only do a few second-long exposures without a mount. My next purchase was a Johnsonian mount
that the Dobsonian sits on. With perfect polar alignment, this
allowed approximately 45 second exposure times. The Connectix
was prone to breaking, so I decided to buy a Quickcam
Pro 4000. The procedure for
modifying this webcam for long-exposure is tricky and
requires some serious soldering work.
I paid someone else to do it and started getting results
immediately. The photos were now
color! Unfortunately, like the Connectix, the wires had a high propensity for
snapping. Finally I broke down and
bought a SAC-7, which is based on the same technology as the Quickcam, but it has already been modified and is put in a
more secure box than the usual Quickcam housing. The problem then was that I had been
using eyepiece projection with the Quickcam, but that
was nearly impossible with this new camera. A friend owned a Celestron
C8 (one of the first publicly available equatorial scopes). I purchased it dirt cheap and started
taking pictures at prime focus (with a focal reducer). Finally in January 2005, I purchased a
Sac 8.5. It is an extremely sensitive
CCD style webcam. I hope to eventually buy a full blown
CCD camera and a GoTo telescope.
