Your knowledge of the skies scares me to death. Very impressive photos and info.
This is/was my tracker. Still have all of the parts. It was a non computer controlled (100% manual) motor driven tracker with only one object in mind. I wanted Hale Bopp. I wanted it
bad. Them things don't come around often. Took me a year to learn how a crappy telescope tripod functions, then many months more time to modify the drive from a manual hand driven, to a variable motor driven drive.
The motor to drive the telescope tripod gear is what I call early Flintstone. It's composed of two Skill "twist" electric screwdrivers with the planetary gear drives coupled together.
The heads in those old cordless screwdrivers are made up of two sets of planetary gears. Four planetary gear sets stacked one on top of another together at about 4 volts, gave me about 2 RPM.
Now
that 2 RPM speed was coupled to an old cordless drill head via a 36" Dremel tool flex/extension shaft.
All of that gear reduction twisted the gear on the telescope gears at about the right speed to take some photos.
Once I figured out the ideal tracking speed through trail and error, I was able to get 3 good shots of Hale Bopp with different lenses.
.................. my life was now complete.
The stress of my self diagnosed OCD just about did me in. I just
had to get photos of this comet. 3200 speed film was not in my plan. Anyone could do that. I wanted 200 speed film and it required 16 minute exposures with my F4lenses
While waiting a year and a half for Hale Bopp to arrive, I nabbed Hyakutake as I was fine tuning my contraption.
In 96 and 97, computer controlled motor drives and tracking systems were just arriving on the scene.
...and they were expensive.
...and I'm cheap.
...and I did it.
............my way.
