We are good to go! I have the DLNR permit for using the site. We will hold the Mauna Kea Messier Marathon 2016 on the evening of March 12 at the Ka’ohe observing site.
The 11″ NexStar GPS telescope, GyPSy set up at Ka’OheSunset: 18:31 HST
Astronomical twilight ends: 19:44 HST
Astronomical twilight begins: 05:19 HST
Sunrise: 06:32 HST
Please arrive before sunset so as not to annoy other observers with lights and dust, allowing a few extra minutes to find the setup site. This will provide plenty of time to set up gear and have a picnic dinner. I hope to be at the site around 5:30pm. I will sign the group in at the check-in station with the permit number, you need not sign in.
For those who wish to marathon I will have a checklist available for the effort. There are a lot of MM checklists, the one I provide is optimized for our 20N latitude which changes the priority of the evening and morning objects. If you do not want to participate, just come to observe.
If you are participating in the MM I would also suggest a low-power, wide field instrument. Smaller telescopes are actually better at this pursuit than larger. For MM I leave the 18″ at home and bring a 6″ telescope. Any finding aids are acceptable, including GOTO. If you are a purist like me? I will use nothing but a chart and a Telrad to locate the objects.
The site is to be found along the old Saddle Road just above the Kilohana hunter check in station. There is a line of pine trees a couple hundred yards above the gate, I plan to set up on the makai side of the trees where you will find a large flat area and a big pile of gravel stockpiled. A precise location and Google map for the Ka’ohe site can be found here.
A reminder that the DLNR permit has a few restrictions, nothing we would not do anyway… No open flame, no hunting, and please keep the area clean.
Now all we need is clear weather for a successful Marathon!
Looking for a site that is a bit closer to home than driving all the way to the Mauna Kea VIS? Maybe not quite as high up the mountain, not as cold or windy? There is not a lot to choose from on Mauna Kea, much of the land is controlled access, either DLNR or private ranch land. Locked gates are the standard solution around the island.
Looking towards Hualālai from Kilohana, a heavy layer of vog sits just below
There is a gate that is generally not locked. The hunter check-in station at Kilohana that provides access to the Kaʻohe game Management Area. Starting at 5,700 feet from the Old Saddle Road the R-1 road climbs the mountain from here.
The actual spot I use is a staging area used by DLNR crews, hunters and the ATV riders who normally frequent the area. From the neat lines of pine trees it looks like the site was once a homestead or ranch house of some sort built high on the side of the mountain. It is about 1/4mile above Old Saddle Road and the Kilohana hunter check in station and directly adjacent to the R-1 road.
As usual you need to obey DLNR rules for access to the site. The R-1 road is designated a public access trail under the Nā Ala Hele trail system, so a permit should not be required. You must not be “camping”, this is defined by the DLNR as being in possession of “camping paraphenalia”, like sleeping bags, tent, etc., during the hours of darkness.
There is a sign in and out form at the hunter check-in station. The DLNR states that 4WD is required to use the R-1 road, but in reality the old homestead could be reached by any vehicle, the first part of this road is quite nice, basic gravel, the rough stuff is far higher up the mountain.
The site has many advantages. It is just far enough off the Old Saddle Road as to avoid vehicle headlights. Not that there is much traffic on the old road, the new road has accommodated most of the across island traffic and it is miles below the site.
One of the best features of the site is shelter from the strong trade winds that sweep across the island. The trades are generally from the northeast, while the site is on the southwest flank, sheltered in the lee of a 14,000ft mountain. I have seen days when the trades were howling in Waimea and Waikoloa, while it was dead calm at Kaʻohe.
You can get some fog and dew here in the evening. At 5,800 feet elevation you are just at the top of the inversion cloud level, sometimes just below. When it is clear it is glorious here, but you can get evening fog until the cooling night allows the sea breeze to wane and the cloud level to subside. You can always pass the site up and head on to the VIS if the cloud tops are higher.
The 20″ Obsession telescope being set up at Kaʻohe, on the side of Mauna Kea
As with any site on the slopes of Mauna Kea, air currents around the mountain can cause some seeing issues. The site should be less susceptible to cold down slope flows than the VIS area as it sits upon a ridge line, not a depression.
The game management area can occasionally be closed to access by the DLNR for one reason or another. You can check the DLNR website or the Nā Ala Hele trail system webpage. Closures should also be marked at the hunter check-in station.
The site is most easily reached from the new Saddle Road (Daniel K. Inouye Highway) in the valley below. Turning up the old road near milepost 42 and driving one mile up to Kilohana. If you see the girl scout camp you missed the turn by a bit.
I have used the site many times, and have also observed from the nearby Kilohana Girl Scout Camp, and been very pleased with the observing. I suspect I will use the site again in the near future.

The 11″ NexStar GPS telescope, GyPSy set up at Ka’OheI have been observing from the driveway quite a bit lately. But I really wanted to escape the neighborhood lights and get some real dark time. Add the vog factor, a thick layer was dimming the stars as seen from lower elevations. A few thousand feet of altitude would solve a lot of problems.
I needed some altitude! But I did not want to go to the VIS, it was cold and windy up there. A compromise was decided upon, if the clouds proved low enough I would go to the Ka’ohe site on the old Saddle Road. Only 5’800 feet elevation is a compromise between getting above the clouds, it is usually just high enough, and staying warm. On the west face of the mountain the winds are usually mild. This is only the second time I have used the site. Not that the site is new, I had noted this place as a possible observing site many years ago, it is only recently I have begun using it.
I have also been working on the ‘scope a bit. Now over a decade old the 11″ NexStar is in need of some TLC. A replaced GPS battery, a new power connector in the base, a little lube in the slip rings, a repaired solder connection also in the slip rings, etc., etc. She is working pretty well now, the GOTO system hitting target after target with precision. Thus I was looking to use the 11″ instead of the 18″, though this limited my magnitude a bit. I set up my observing lists for a maximum magnitude of 13.
What to observe? Just query my observing list generator for a list of whatever I have not observed in the area. I usually work in 30° x 2 hour section of the sky. This evening would see me south of Orion in Lepus, Eridanus, and Columba. What I did not expect is that everything I had not observed down there was a small, dim 12-13 magnitude galaxy! Everything!
NGC1993 Small, very faint, round 1′ in diameter, stellar core
NGC2089 Small, faint, round 1′ in diameter, stellar core
So it went, galaxy after galaxy, the variation was usually some version of faint… “Faint”, “Very faint”, “Quite faint”, to the limit of my vision “Averted vision required with the 28cm”. A bright star or another galaxy in the same field was exciting!
Normally when working a region of the sky I find quite a few plain objects, the usual slew of dim galaxies when off the galactic plane, open clusters in the plane. Usually there is the occasional gem sprinkled in to liven the observing session. Not tonight!
Still, it was very nice to be out under the stars. It was a completely dark night, the sky brilliant with Orion and Canis Major high overhead. I was sitting just at the top of the cloud deck, the cars far below me on Saddle Road creating a dim glow in the clouds. Across the top of the clouds I could see Mauna Loa and Hualalai lit by starlight and skyglow.
A solid three hours at the eyepiece, three pages of notes, and I was out of hot tea. I put down the unending list of dim galaxies and just spent a bit looking up some old favorites. The Orion nebula was stunning in the eyepeice, R Lep is still very, very red. Finally breaking down and heading home, I was in bed about midnight.
My 18″ telescope Deep violet set up under the stars at the MKVIS.There have been some revisions to the rules as originally proposed. Most notably the closure hours begin at 10pm in place of 8pm, this would allow the VIS to operate the normal evening public program.
I have yet to locate a copy of the final approved rules, it is only a few minutes ago that the decision was approved. I expect they will appear on the DLNR website eventually (Tonight? Monday?). They are effective immediately, I would expect there to be a legal requirement to post them.
It is safe to say that there will be no overnight observing at or near the Mauna Kea VIS. You will need to find a site elsewhere or at least one mile from the access road.
These rules are effective for 120 days, after which we will see what happens. In that time they may be allowed to lapse. It also allows the DLNR time to approve similar, permanent rules through the regular process in place of these emergency rules.
120 days and counting… I make that November 8th, 2015.
Update: Found them!
(a) The area referred to in this rule as the “restricted area” is defined as any lands in the public hunting area that includes the Mauna Kea Observatory Access Road and one mile on either side of the Mauna Kea Observatory Access road.
(b) As used in this rule, the term “transiting” means operating, or being a passenger in, a motor vehicle traveling at a reasonable and prudent speed and having regard to the actual and potential hazards and conditions then existing.
(c) No person shall at any time possess or control in the restricted area any of the following items: sleeping bag, tent, camping stove, or propane burner.
(d) No person shall enter or remain in the restricted area during the hours of 10:00 p.m. to 4:00 a.m., unless the person is transiting through the restricted area on the Mauna Kea Observatory Access Road or is lawfully within or entering or exiting an existing observatory or a facility operated by the University of Hawaii.
As we are all aware, the TMT protests are having direct consequences for everyone who goes to the mountain. Regular mountain users and tourists alike are dealing these consequences. The summit road closed to the public for a second week, the MKVIS also closed, even before these closures the protests had curtailed many activities.
My 18″ telescope Deep violet set up under the stars at the MKVIS.It looks to get worse.
Go the the Mauna Kea Visitor Information Station on the weekends nearest new Moon and you will find telescopes. While the MKVIS telescopes get put away at 10pm there are ‘scopes that are operating late into the night, often still there when dawn colors the sky. These telescopes belong to local amateur astronomers who bring them here to enjoy perfect Mauna Kea skies.
It has been over three months since the protest began. Three months of standoff with the protesters who would not see another telescope built on Mauna Kea.
My 18″ telescope Deep violet set up under the stars at the MKVIS.It has been my habit over the last eight years to spend a night under the stars, high on the mountain, each time the new Moon arrives. On the nights when there is no moonlight the sky is dark, truly dark. The stars shine undiminished, the universe is open to be explored. I have used binoculars, small telescopes, cameras, or simply my eyes.
It is with my handmade 18 inch telescope that I can truly gaze into the depths of space. This simple device of plywood and glass allows me to see galaxies millions of light years into the past. With this telescope I have seen hundreds of galaxies, giving me a glimpse of the indescribable vastness of space.
Often I would set up in the patio right at the Mauna Kea Visitor Information Station. The first couple hours spent talking with visitors, showing them the wonders our universe has to offer. After the VIS closes the visitors depart, driven back to their hotels by the cold mountain air. I have a heavy winter jacket, ski-pants, a thermos of hot tea, everything I need to be comfortable under the night sky. I would have the rest of the night to myself, just me, the mountain and the stars.
The plan was to do some astrophotography Saturday night. The weather forecast forced a re-schedule, a winter storm arriving Saturday afternoon, Friday it was to be.
The Pleiades, M45, with the Canon 6D and TV-76mmThe timing proved to be excellent, Mauna Kea providing glorious skies Friday night. Clouds hovered over the side of the mountain on arrival, but there was no worry. These were the sort of clouds that would vanish with the daylight. Anxious tourists wanting to see through the telescopes repeated the same question, will the clouds go away? I answered the questions with the relaxed assurance of experience of years on Mauna Kea, and continued to set up the gear. The clouds didn’t even last as long as I expected, dissipating as the sun settled into the horizon.
Setting up at the Mauna Kea VIS means a crowd of people. Hundreds of tourists that have come to enjoy a dark Mauna Kea Sky. I was joined by Raymond, a Hilo amateur also looking to take some photos. We setup side by side in a parking space just off the patio where the VIS was setting up their telescopes for the night. We would be in the center of the crowd for a while.
Amateur astronomers love lists… The Messier observing list, the Hershel 400, the Hershel II, and on. Some lists can be complete on a night or two, some lists may take years, or even a lifetime to accomplish. Amateur astronomy is not the only avocation to use lists like this. Birders attempt to see all of the birds known to occur in their home country. Aircraft spotters love to see each model of aircraft in the air. Divers keep lists of species seen underwater.
Lists like these are not only fun, but allow the list chaser to sample the wonders our universe has to offer. The challenge of finding and observing each of the items is worthwhile. Each object is a lesson into the science, hunting each object allows skills to be practiced.
Most of the astronomy observing lists require a small telescope to accomplish, or at least a pair of binoculars. One list is a bit different, it does not require any optical aid at all… The Naked Eye 100.
