With the big wall completed along the driveway, and a bit of a break over a hot muggy summer, I am again building walls.
This is not the sort of wall between people, I detest those, but rather a real rock wall, terracing the backyard to make the space available for landscaping and other projects. This puts into action a plan that has been brewing for years.
Part of the impetus is that I have a source of rock secured, a very large pile of very nice rock found in a Waimea backyard. One of my co-workers casually mentioned he needed to rid himself of a pile of rock, to which I quickly asked… How much rock?
The classic Cave Astrola telescope has become my roll-out, quick observing session ‘scope, often found in my driveway. I have also used it a few times at darker sites when I expect the weather to be damp or dewy as a Newtonian is more protected.
While the restoration job was finished some time ago, I never got around to re-coating the optics. Meanwhile the telescope has seen good service on many occasions as I enjoyed this fun-to-use instrument.
The optics did need some attention… The primary mirror from the Astrola appeared to have not been re-coated since it was made in 1978. Thus the aluminum coating was over 40 years old. While the coating looked bad, it was still serviceable, producing reasonable images.
Still, the loss of light due to the old aluminum coating was probably reducing the effectiveness of this 8″ telescope to something more like a 6″ telescope. I had meant to get it re-coated some time ago, but we know how these things work.
I do enjoy a nice project I can work on, get my hands dirty, and use my skills. A classic telescope in need of restoration? Just the thing.
This telescope was literally rescued from the trash. Matt, the owner of the excellent Mountain Road Cycles in Waimea found the telescope at the transfer station.
Matt put a message into the folks at the observatory, who represent more than a few of his customers. The info was quickly forwarded to me, as everyone here knows I build and restore telescopes for fun.
My Astrola is now operational, with final assembly and collimation completed a week ago. So far I have used it for several evening sessions of observing from the driveway. The result is several pages of notes in the observing log, wandering through nebulae, clusters, and binary stars in Orion, Canis Major, and Puppis.
When I was just starting my journey in astronomy the Cave Optical advertisement in each month’s Sky and Telescope was something to inspire dreams in a young teenager. In many ways those dreams have never been forgotten.
Yes, a new/old telescope has arrived at Andrew’s Home for Wayward Telescopes… A beat up and neglected 8″ Cave Astrola. The new arrival has me thinking of the other telescopes that have come through recently…
I have previously published a description of Hodgepodge, the mish-mash mount I used for the solar eclipse. While I wrote about the mount, and posted some photos, I did not really cover the construction. Now for some details…
With the solar eclipse looming on the calendar I realized I needed a tracking mount to allow photography. Tracking would allow me to keep the Sun and Moon in the field without wasting precious seconds framing the image during the eclipse. It would also enable longer exposures without motion blurring the image.
Due to lucky happenstance the location for Oregon Star Party, the same location used for decades, was within the path of totality for the 2017 total solar eclipse. This provided an opportunity to both attend the star party again, and to view the eclipse.
I do enjoy the large star parties, something we do not have on the island. I had attended OSP a few years ago, the eclipse made the opportunity to attend once again very tempting.
Registration for the star party was an issue. Due to the eclipse attendance was going to be very good, so good that registration was closed within two hours of opening! I got the announcement email, then waited until I got out of a meeting to register, only to find out I was too late! I put my name on the waiting list and hoped.
With a month to go I received word that my waiting list position was opened for registration. By this time my family already had plans to camp in the Ochoco Mts. for the eclipse, no reason not to do both!
