Jupiter High

Jupiter passed through opposition back on March 7th. Thus the giant planet is high in the sky through much of the night, well placed for observations.

Jupiter on March 24th from Waikoloa
I was thinking of going to bed, but it was a hot windless evening in Waikoloa, not much point in trying to sleep before it cooled off a bit. The dead calm conditions made me think… What is the seeing like? A question only an amateur astronomer would ask.

Turns out the seeing was pretty good. The typical horrible seeing in Waikoloa is 2 to 3 arcseconds or worse, when the trades are blowing it can be quite bad. I suspect the seeing was 1 arcsecond or better last night, the view of Jupiter in the eyepiece was quite pleasing. Putting a camera in place of the eyepiece yielded video worth the effort in processing.

Full Moon

Full Moon
Full Moon taken 27Aug2007, 90mm f/12 APO and Canon 20Da
Full Moon will occur today at 02:01HST.

This full moon will feature a penumbral lunar eclipse visible across the Pacific region. It will be well placed for observers in the Hawaiian Islands where the entire eclipse from beginning to end will be visible. Do not expect much, penumbral lunar eclipses involve only a slight dimming of the Moon, it is unlikely to be noticeable without instrumentation.

Natural Bridges

Still working on scanning the slide collection, I will probably be at it for years. Worth it though, so many memories. Here are a few images from a visit to Natural Bridges National Monument in 1993…

Vernal Equinox

The vernal or spring equinox occurs today at 18:30HST. Today there will be little difference between the length of the night when counted against the number of daylight hours. This is the first day of spring as marked by many cultures in the northern hemisphere.

A Solo Messier Marathon

Yeah, I did another Messier marathon, You know, that crazy exercise where you attempt to find all 110 Messier objects in a single night. A bit crazy, but also rather addicting. I am a somewhat of a purist, I use no computerized telescope, just a chart, a Telrad, and my knowledge of the night sky. This makes a Messier marathon a real challenge.

The Clouds at Sunset
A few clouds wandering across the western horizon, some near, some far. At least there is some blue sky!
I had invited a few other folks to join me at the Kaʻohe observing site on the side of Mauna Kea. A few other observers had indicated they would be there, I even had a DLNR permit for a small group to join me and a few extra checklists printed out. It was the clouds that convinced the others not to make the attempt. Thus, in the end I had the night to myself. Mostly.

Even if the clouds spoiled the event there was not much to risk. May as well pack up and drive to the site, as the organizer I pretty much had to be there in case any of the others responded to my invitation. This outing would not take much preparation, a cooler packed with munchies and drinks to get me through the night and one of my smaller telescopes. There is not much question as to which telescope I will use… Primero, my 6″ RFT and the veteran of many Messier marathons. it is this instrument with which I achieved my one perfect 110 score at the All Arizona Messier Marathon many years ago.

MIlky Way Arching over Hualālai

My first attempt at a proper Milky Way arch photograph. Not easy to stitch properly, but worth the effort! Click on the image for a file size large enough to properly enjoy…

March 8, 2016 Solar Eclipse from Kawaihae

The seeing was terrible, but at least we could see the Sun while much of the island was overcast and raining. I had hoped to set up in the parking lot for Puʻukohala Heiau but arrived a few minutes after they closed the gate. Instead I set up just below at Spencer Beach park.

Of course the telescope drew a crowd of folks who wanted a look. No matter, an eclipse is a slow motion affair with plenty of time to share the eyepiece. I showed my guests how to take photos with their cell phones at the eyepiece, so everyone got a photo or three of the event.

New Moon

Young Moon
A very young moon over Waikoloa, this is only 26 hours after new, visible to the unaided eye as a sliver in the fading glow of sunset
New Moon will occur today at 15:45HST.

This new moon will feature a total solar eclipse that sweeps from Indonesia across the central Pacific. It will be visible as a deep 50% plus eclipse in Hawaii.
