I had decided to spend the night of Friday, June 19 in Redding, at the Best Western Hilltop Inn, in order to arrive rested in Adin on Saturday. On Friday night, I enjoyed a nice dinner with David Cooper, who was also staying at the same hotel.

The short drive to Adin on Saturday morning was uneventful, and I arrived at the camp site around noon, promptly setting up my tent on Uranus row. Since the weather outlook was not looking very promising at the time, I made the decision to leave my scope in the car. This turned out to be a smart move because Saturday night was wild, with lightning, heavy rain, and even hail! My small tent handled the elements remarkably well, and I remained dry all night, unlike a few others…

On Sunday afternoon, Rogelio, David and I visited the Lava Beds National Monument. This was a fun outing, although it was a fairly long drive (3 hours round trip from Adin) During the day, the weather forecast gradually improved, and the sky turned mostly clear after sunset. Because of a few high altitude clouds, the sky that night was not nearly as dark as it could have been. I got NELM 6.7 in Hercules.

Monday night was slightly better. Alvin and I both got NELM 6.9. This was still a bit disappointing. Under such dark skies, when the conditions are ideal, one can get NELM 7.5. Tuesday night was probably the best one. After a really hot day, I got NELM 7.0 in Hercules. The milky way looked absolutely gorgeous, all the way down to the southern horizon. The seeing was about average on all three nights, although it felt a little more solid on the last night.

I had put together a list of about 60 objects, most of which from the Herschel 400, containing mostly galaxies, nebulae and globular clusters. I did not want to observe too many open clusters from such a dark site, because those can be observed under less than ideal skies from the bay area. I ended up observing about 40 of those objects, leaving enough time for some free-style eye candy that I did not log. Some of the highlights include observing the central star in M57, as well as the nearby IC 1296 galaxy in Alvin Huey’s 22″ scope. The crescent nebula was also putting on quite a show through my scope using an OIII filter. Finally, seeing both arches of the veil nebula in one field of view through David’s 80mm refractor was really amazing!

This was my first out of town multi-day star party, and I thoroughly enjoyed it. Most of all, it was really great to finally meet a lot of TACos in person. The food cattered by our host, the owners of the Frosty Acres ranch, was absolutely delicious. The shower truck was awesome! A big thank you to the GSSP organizing committee for putting together the star party, and to David Cooper, who shared his canopy, and saved me from getting burnt by the Sun…

NGC 7008 PN Cyg 21h00m51.0s +54°34’41″ 12.0 mag 01:40a
Relatively large and pretty bright planetary nebula. Appears elongated 2×1 N-S at low power. Using a higher magnification and an OIII filter, I can see 2 lobes positioned on a N-S line, the one to the north being the bigger and brighter one. Without the narrow band filter, the central star was easily detected, as well as a superimposed star to the ENE and 2 fairly bright stars located SE of the nebula.

NGC 6369 (Little Ghost Nebula) PN Oph 17h29m57.6s -23°46’05″ 11.0 mag 11:50p
Pretty small, pretty faint, round, uniform, looks like an out of focus star at 95x. Delicate ring structure suspected, confirmed at 219x using a UHC filter. I did not see the central star. Northern rim looks very slightly brighter. Reminiscent of M57, but much smaller.
