Cherry Blossom Festival is a huge event where a large segment of the island population descends upon Waimea for a day of celebration. there are booths and events all across town. There are cultural demonstrations, cooking demonstrations, performances, and lots of food available for an all day, all town festival.
Viewing the Sun at the Cherry Blossom FestivalWith most of the parking on the south side of Keck observatory, the shopping mall parking lots, and the main event venue north of Keck at Church Row where the cherry trees are, a huge number of people cross the observatory lawns on their way to the festival. It is a natural fit for us to use the day for an outreach event.
The festival is also a very local event. Sure there are a few tourists drawn to Waimea for a festival. But, by and large this is a local event, the majority of attendees are island residents.
As the TMT contested case drags on we continue to watch. Thanks to the efforts of the staff of Nā Leo TV the entire proceedings are streamed live. Several of the latest witnesses for the University are Hawaiian supporters of the telescope project, it is these voices that I am most interested in hearing.
Retired Judge Riki May Amano presides over the TMT contested case hearingIt is when the questioning begins that things get ugly. Question after question challenges the integrity of the witness. The questions challenge their personal values as if to say “You are not Hawaiian.” Over and over the questions were repeated, each successive question designed to attack the cultural identity of the witness…
“Where did you grow up?”
“How old were you when you learned that?”
“Who taught you that?”
“When was the last time you were on Mauna Kea?”
“When did you last worship on Mauna Kea?”
“Where did your family worship?”
“Do you pray to Poliʻahu?”
“Who are the parents of Poliʻahu?”
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.
A set of cheap Chinese eyepiecesThus I went to the source of cheap optics and found a set of Chinese eyepieces on eBay that might just do the job. For $22 they were the right price. The set includes three eyepieces, a 23mm, a 10mm and a 4mm for high power, a nice selection of focal lengths. The right price, but how about image quality?
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.
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.
A Celestron FirstScope in somewhat larger companyThis telescope is now headed to a new home. With Christmas approaching another co-worker asked my opinion in buying a telescope for his eight year old daughter. She had expressed interest and he was wondering what to get. Quick to size an opportunity to divest myself of an unused telescope I let him know I had just the thing! One less mirror to clean. Rob of course was quick to seize on the idea of free.
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.
The winter Milky Way over the summit of Mauna KeaThe question strikes a particular resonance with me, returning to my thoughts again and again. I consider my relationship with the mauna, is it pono that I continue to work at an observatory and support the construction of TMT?
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.
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.

In restoring a 20″ Obsession telescope I found myself pulling a book from the shelf that had not been opened in a while. David Kriege and Richard Berry’s The Dobsonian Telescope – A Practical manual for Building Large Aperture Telescopes is a book I once read cover to cover.
My copy of The Dobsonian Telescope by David Kriege and Richard BerryThe information here was critical in the success of my building Deep Violet, my 18″ telescope. Within the pages of this book are plans and drawings of the important bits as well as detailed discussions of what does, and does not work, when building a telescope.
The Dobsonian Telescope is the primary reference for those building large amateur telescopes. This book, along with the design revolution that went with it, put large telescopes in the hands of countless amateur astronomers. These telescopes extended the capabilities of amateur observers immensely, allowing spectacular views of deep space objects that were only fuzzy smears in the eyepiece before. Want to see the spiral arms of galaxies? A 20″ telescope can do that!
As I perused my well thumbed copy I was surprised to find bits of my own telescope plans used as bookmarks. There was dust on the top of the pages, but I still remembered where I disagreed with Kriege in the dimensions of the mirror box, or how to place the truss tube clamps. I may have deviated from the plans shown here in some aspects, but in other parts of the design I directly used the dimensions shown in the book.
So many old memories, good memories. Pursuing an art that has been around for four centuries, combining bits of wood and glass to make an instrument that can reveal our universe. Sure you can simply buy a very good modern telescope. But it is hard to overstate the pleasure of building one yourself. This is an art that can still be done in a garage, with tools available at the local hardware store, with results that can rival or even surpass something purchased from a catalog.
