Finally, projects that have been sitting around for a while are getting done -- part of the point of taking time off was to get as many projects over the hump as I could, in the hope that I could stay caught up once I get back into a work schedule.
It's nice to have some of them finally coming off the list. Here's one of the first:
This one was fairly simple, only a couple of hours -- but it's been sitting around driving me crazy for months, because it required getting access to the drill press in the workshop, which was stuck behind stuff, which required... you get the point (my life, it's just a Gantt Chart with a big thick line on the critical path marked "you'll never get to this".
We've owned a telescope -- a Meade ETX-90 -- for a number of years, but we just don't use it very often, because set up time gets in the way. It's a nice unit, but you really need to plan ahead to give it time to cool and to get it set up and aligned and working -- it's enough to keep us from using it a lot (hopefully, that'll change).
For some things, especially planetary observing and solar work, you really don't need the complexity of a scope; good binoculars will do. I bought a set of Orion 25x100 binoculars. Really good, quality astronomical binocs -- but they weigh 10 pounds. Not something you'll ever hand hold.
I also picked up Orion's Binocular mount and tripod, which uses a parallelogram type strut to allow you to move the binoculars around and share them with other people without losing your aiming. Like any good geek, I felt they were almost perfect, but I needed to make a couple of changes. So the tripod went into the garage waiting for a few hours of free time...
And waited, and waited, and got stuff tossed on them, and waited some more, and.. (you know how it goes)
But now, it's done: here are the changes I made:
First, I wasn't thrilled with the binocular mount, especially with my binoculars. At 10 pounds, those buggers are huge, and heavy, and they needed a stronger and more flexible support. Also, I standardized on a specific quick release mount for all of my cameras and opticals, and I wanted to use the same mount on this for simplicity: it means I could, potentially, carry these binocs and use them as a spotting scope on a standard tripod while birding if I wanted to (and hired a sherpa....)
Since I use the RC2 mounting plate from bogen/manfrotto, I replaced the standard mount with the Bogen 3030 3 way, a good, solid and flexible tripod head.
(digression: why do I use the RC2? it's a good, solid quick release -- and it has a locking switch in the unit, which means you don't have to worry about he quick release releasing if you hit it wrong; I REALLY like the having a little measure of safety here for some reason. Maybe it's having expensive optical gear hooked up that you don't want to land on the ground at a bad time...)
The other change was a bit more involved.
The mount offsets the weight of the binoculars by using a weight attached to the end of an adjustable rod; the idea being you can make the unit weight-neutral. The standard unit comes iwht about a 15 pound weight at the end of an 18" rod. that rod's not removable, which I found made moving and storing the unit around awkward; worse, the weight wasn't enough to balance binoculars of those size.
What I ended up doing was replacing the standard rod with a longer threaded rod. By pushing the weight out further, I can use a lighter weight to balance the binoculars; 15 pounds instead of 25. Once I found weight neutral, I drilled two holes on the rod for cotter pins, so I could make the rod/weight part removable, but install it and secure it without having to adjust it; if I put something else on the unit, I can remove the pens and use the original friction lock.
It can be set up and in use in about two minutes now. By splitting the weight and rod into a separate piece for moving, it's now easy to stuff in a car (or a closet), or haul outside for use. And of course, the easier it is to use something, the more likely you will, right?
Now, I just need to find my solar filters. I know they're around here somewhere.
