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

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!

Connecting the Community

This island is a small community, anything that happens is likely to involve someone you know, or a friend of theirs. There are often only a one to three degrees of separation between you and nearly every event that makes the local news.

Even someone who has not grown up here seems to become quickly enmeshed in the community… One day I hear news of a body being discovered on a remote Kohala coastline by kayakers. The next day at work I ask Peggi about her husband’s kayak trip… As you guessed, they found the body. This may seem unusual, but here these sort of linked events are commonplace, amplified by the small community effect.

It is amazing how fast information moves from mauka to makai, the grapevine is very well connected on this island. This connectedness is accelerated by social media. Where once you would have to wait hours or days for official confirmation, or a newspaper report, we now know immediately.

There are specific places everyone goes for this type of informations. Two notable Facebook groups cover island happenings, Big Island Thieves and Big Island Popo Alert.

Neptune at Opposition

Today the planet Neptune will pass through opposition, directly opposite the Sun in our sky. The planet will be well placed for observation all night long, rising at sunset, transiting at midnight, and setting at sunrise. If you are looking to observe Neptune, it is currently shining at magnitude 7.8 in the center of the constellation Aquarius.

As the outer planets Uranus and Neptune move so slowly across the sky, the timing of oppositions is driven by the Earth’s orbit and occur each year at nearly the same time. Neptune’s orbital period is 164.8 years, taking over a century and a half to circle the celestial globe once. As Neptune was discovered in 1846, it has completed a little over one orbit since discovery.

The Impact of Totality

Having recently viewed a total solar eclipse I have been thinking about the experience. What it was like to observe first hand a truly incredible spectacle of nature? A total solar eclipse is about as dramatic an event our world can produce.

This is not my first total solar eclipse, but that first eclipse was back in 1979, occurring 38 years ago, my memories dimmed by the passage of time. This event is still bright in my mind, the memories bolstered by numerous photographs and a couple video records.

The experience was astonishing. For the first thirty seconds or so I simply sat in amazement, observing the eclipse and the world around me. Despite old memories and numerous photos I was still amazed by the sight. I knew what was coming, but I was to some extent unprepared for the sight before me. Eventually I gathered my thoughts and took some photos before the fleeting moments of totality expired.

In these modern times we rarely encounter a natural phenomena we are completely unprepared for. Prior to the event we have seen photographs or video, read descriptions from others. We generally know what we are about to encounter beforehand, or at least have a name and a cause we can understand when caught by surprise.

Imagine if that was not the case, consider seeing a total solar eclipse when you have never seen one, never even heard of such a thing, and do not know something is about to happen.
