My equipment
15" f/4.5 "Obsession" style dob
- Built using Kriege/Berry's "The
Dobsonian Telescope" book's guidelines
- Swayze optics primary
- 2.6" Nova enduro-brite secondary
- Starlight Instruments "Feathertouch" focusser
- Crosman "red dot" finder
- University Optics 8x50 finder
- The Sky Commander you see on there is gone. I just stopped using DSCs
and finally sold it after a few months of disuse.
You can check out some construction info on my ATM page here.
Observation desk/chest The idea for this has probably been
used many times, though mine is a copy of one made by another Lowbrow
Astronomer, Chris
Sarnecki. It is just a cheap ($20 on sale at Target) wooden footlocker with
four long wooden legs screwed on the bottom (the legs remove for transport).
It has two compartments under a 1/4" plywood top; the larger
compartment on the left is used as a library, and the smaller one on the
right is currently being used as a toolbox, containing a plastic box with
screwdrivers, nylon tie-wraps, pliers, and other generally useful stuff, and
a 12V hair dryer (pick up from truck stop for $15).
Log computer. This is a venerable TRS-80 Model 100 laptop,
really the first laptop ever, introduced in the early '80s.
I use it to take notes in the field.
I found that if I wrote notes with a pencil, by the end of the night the
notes were terse or nonexistant, and illegible.
NOTE: as of spring 2003, I've switch to using a microcassette recorder,
taking voice notes, and transcribing them after the session. It seems like a little
more work, but I find I get a whole lot more observing done, since it's much faster
to dictate than to type in the dark. Plus I can type later with the lights on
and on a real machine than I can in the dark.
Here is some of the other stuff in the fleet:
- Edmund Astroscan scope for travel - includes a couple of plossl eyepieces.
- Howie Glatter laser
collimator - if you get this, plan on loaning it to neighbors at every
star party you go to! However, note that you STILL need a good cheshire/
sight tube collimation tool; the laser doesn't do everything, though it's
a good final step.
- Nagler 22mm type 4 eyepiece
- Pentax XL 10.5mm ep - this is one sweet hunk of glass.
- Televue Radian 5mm
- Televue 1.25" 2x barlow - the Pentax responds well to this.
- Lumicon UHC filter 1.25"
- Thousand Oaks OIII filter 2"
- Moon filter, a few color filters 1.25"
- Minolta XL 7x50 binoculars
- Celestron 15x70 binoculars
I have the following star charts:
- Pocket Sky Atlas - this is really all I use anymore. Plenty of objects
to keep anyone busy, good indexing.
I used to have a copy of Uranometria, but it was too much trouble to lug
around all the time. It's awesome but I just wasn't using it.
I also print individual finder charts for objects using Sky Tools
occasionally.
