Restoring the 8″ Cave Astrola has me again looking at these classic telescopes. Reading the history of Tomas Cave and Cave Optical. Looking at the old advertisements and remembering things long thought forgotten. I may never have owned one before, but the Astrolas still had an impact upon me years ago.
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.
Cave Optical Advertisement 1970, from Phil HarringtonWhen 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.
Light pollution, a subject near and dear to any sky-gazers heart. It seems we are always struggling to educate our fellow citizens that more is not better, it can be far worse, particularly when it comes to the subject of artificial light. We are at odds with the child inside all of us that delights in the creation of light, a magic that never seems to lose its charm.

Light at night consumes a lot of energy, megawatts that are simply wasted illuminating places where no one sees it. Or worse, mega watts that are shone into the sky where it has no benefit at all.
Artificial light harms many species that live near our cities and towns, birds, sea-turtles, and more lured to their doom by the lights. The light also harm us, disturbing circadian rhythms and other natural cycles necessary for good health.
Light pollution also obscures the stars, drowning out the universe that would otherwise shine brightly overhead. Besides being a subject we should all care about, the night skies have a real economic impact here in Hawaii, a state largely dependent on a healthy environment and the tourists that come to enjoy that environment.
There are quite a few different bills proposed for this session of the Hawaii legislature that address astronomy and Mauna Kea. Of the more interesting there are proposals for an independant manangement body for the mauna, 4WD drive access to Mauna Kea and Waipio valley, addressing light pollution, and an audit of OMKM.
Sunrise over Mauna Kea greets me on the morning commute.As some of these proposals have a direct effect on the mauna and upon me personally I intend to address each of these proposals in blog posts. I also intend to submit testimony on these bills, reading and blogging on them will help.
As usual for the Hawaii legislature there is occasionally both a house and senate version some of the bills. These must be reconciled in the end as they wend through the rather interesting process our state lege uses. Several of these have passed first reading, the first weeding out of bills in the process for this session.
Time to remind everyone of the common rules for star party etiquette. As few simple considerations for your fellow star party participants help make the event more enjoyable for everyone.

Not to say these are hard rules, they will get broken. Try not do break these rules… It is simply a matter of courtesy to other star party participants. Be polite and you will be far more welcomed to share the experience under a dark sky.
The points of etiquette below apply to any star party you might attend, with a few added bits particular to our West Hawaii Astronomy Club events.
A few months back I was reminded that I was remiss in scheduling proper club star parties. Thus I set about fixing that!
A telescope and observing table in the dark at KaʻoheWhat about a site? The MKVIS at Hale Pōhaku is a total zoo lately, too many tourists, folks from the club are hesitant to go there for a good dark experience. it can also be cold and windy up there. Since Vaughn left the island a few months back, no one is using the old upper road site at Puʻu Kuainiho.
Thus I compromised at using my favorite site at Kaʻohe. At 5,800ft the site is lower, warmer, and less windy than the VIS. It also represents about half the drive time it takes to get to the VIS, without the tourist crowd. The site is higher and offers more reliable skies than the Puʻu Kuainiho site
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…
