Consequences of a Bad LED

A bad indicator LED, a simple ten cent part brought the Keck 1 telescope to a stop this last week.

How can that be? Usually an indicator is just that, an indicator. While an LED may indicate a problem it is rarely the cause of the problem.

I was getting ready to leave the summit when the radio started to speak words of concern, it sounded like something was not working, an instrument rotator?

Worse, the Keck 1 computer room hosted a veritable crowd, from the summit supervisor to all of the techs. Yeah, this was not good, why are they all looking at me? Oh, h%#*!

A Waikoloa Star Party

It started simply enough… Donna asked for suggestions, she was looking for activities the Waikoloa Village Association could share with the community. Of course I suggested a star party. Much of our small club lives in the village, this would be an easy and fun event to put together. Al we need is a date and a place.

A date? Sept 23rd would offer a slim crescent Moon, Saturn, and the Milky Way overhead. The 23rd has the added benefit of being a Saturday.

A place? The Waikoloa Stables have ceased being a place with horses. There remains a nice lawn, bathrooms, and a large parking lot. The stables currently hosts a thrift shop and regular community events like the yearly Wiliwili festival.

A plan? Easy… Light refreshments, parking coordination, keiki fire dancers, the local CERT team for safety backup, a sound system, a speaker for the evening, and at least five telescopes for viewing. OK, maybe not so simple.

We can do this.

Hodgepodge: The Mishmash Mount

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…

Hodgepodge and the Eclipse
Hodgepodge set up at Grant’s Spring to photograph a total solar eclipse
A few months back I rebuilt the drive unit of an old Celestron mount, installing a drive corrector into the base unit in the process. I have used this sidereal drive for time lapse, but it can also be used to mount a telescope again. Better yet, with a few minutes reconfiguration, it can do either.

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.

Oregon Star Party 2017

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!

A Night in the Meadow

This little meadow is is only a couple acres. Along one side is a spring where crisp water seeps from the ground and marks the beginning of a creek. Along the top the last few hundred feet of the paved road ends at a junction of rougher roads that lead further into the forest.

Grant's Spring Under Stars

At the very center of the meadow a large snag stands alone, broken off twenty five feet above the ground, a tangle of limbs on all sides. This old snag is a dark sentinel in the night, almost unreal and a bit eerie in the gloom, it seems to move when you are not looking.

The clearing is surrounded by seventy foot high trees. Pine, fir, and larch are all represented in the dense forest that covers much of the ridgeline. This limits the view, blocking objects low on any horizon. The tall trees also provide a stage above which the stars rise and set, sometimes blinking brightly as they pass behind branches.

There are simply no lights, no substantial civilization for fifty miles in any direction. There are no distant domes of light visible on the horizon to remind one of Edison’s terrible invention. There is just the darkness and the stars above.
