The TMT Contested Case Proceeds
We have been through weeks of the TMT permit contested case hearings at this point, with no end in sight. I have often kept the live feed in the corner of my computer screen through the day.
Other petitioners seem unable or unwilling to understand repeated instructions from the hearing officer. At least most of the grandstanding has settled down as it became apparent that it would not be tolerated in the hearing room and that Judge Amano would evict those who repeatedly disrupted proceedings.
Some Chinese Eyepieces
A Celestron FirstScope in need of eyepieces. Time to find a couple inexpensive eyepieces. With the telescope destined for an eight year old girl I really did not expect the eyepieces to live up to any demanding standards. But neither do I want the views to be truly horrible either, it would be nice if the telescope is properly enjoyable.
As the eBay sale is from a US seller the eyepieces arrive in just a few days. Unpacking the eyepieces is the first pleasant surprise… The quality is not bad, metal barrels, decently molded rubber bits, decent looking glass. An ebay sale often a bit of a gamble, but this does not look bad at all.

A Celestron FirstScope
I tend to end up with telescopes, they just appear on a semi-regular basis, given to me with the instructions to find a home for them. One of the latest additions to Andrew’s Home for Wayward Telescopes (AHWT) was a Celestron FirstScope. It was bequeathed to me by a co-worker moving to the mainland and thus dwelt for a time in my office, there being little room in my garage for yet another telescope.

Alone with the Mountain
Several times during the recent contested case hearings I have listened to telescope opponents ask witnesses on the stand and under oath, “Have you asked the mauna?” or “Have you asked Poliʻahu?” I have heard a dozen variations on the question, but that is the general sense of it. They are asking if the witness has asked the gods or goddesses who are reported to dwell on Mauna Kea if building the telescopes is allowed. Poliʻahu in particular, the goddess of snows and ice, is identified with the summit of Mauna Kea.
I think of all the nights I have spent alone on the mountain. So often I have sat in the quiet, with nothing but the mauna and the stars. Sometimes I am sitting beside a small telescope, and taking a break to simply enjoy the night. Sometimes I am waiting for a camera, somewhere nearby in the dark. Sometimes I am just sitting doing nothing at all, simply enjoying the beauty of this place. In any case I am alone with the silence, the stars, the mountain, and my thoughts.
Modding the HBS
Just checking to see if I got the wiring right. Some modifications to the telescope HBS, Hydraulic Bearing System, to allow for a slower startup. Some new hydraulic valves installed by Mark, a few new relays added by me, and the job is done. Hopefully less sputter and spitting on startup to keep the oil off the drive tracks. The system is a classic relay logic controlled setup, seriously old-school.
