1920 MST: LX600 ON, StarLock OFF, High Precision OFF.

1922 MST: viewed the Moon in the 12" telescope, 102X.

1923 MST: Wi-Fi ON. Did some ScopeBoss tests. 1929 MST: Wi-Fi OFF. Ended tests. Then relaxed for a few minutes on the patio bench.

1950 MST: ETX-125 ON. 1954 MST: saw the first Kissing Bug of the night (on top of the dome). It was terminated a little later. 1956 MST: viewed the Moon in the ETX-125 Observer, 73X.

Mounted the iPhone 6s Plus on the ETX using the Levenhuk Smartphone Adapter and used the iOS app NightCap Camera for this afocal 73X image:


Added a 2X Barlow Lens for this image of Mare Crisium, afocal 146X (Camera app):


Then viewed Jupiter, 146X. The four Galilean Moons were nicely visible. Took this afocal 146X image of Jupiter using NightCap Camera:


Viewed Jupiter, 196X. 2040 MST: ETX-125 OFF.

2052 MST: returned to the 12" telescope and took a final look at the Moon and then Jupiter, 102X.

2130 MST: began preparing the D7200 DSLR for prime focus + focal reducer imaging. Slewed to M9 (globular cluster), which would be the first target once it was above the tree to the southeast.

2140 MST: did some sky observing from the patio using 12x50 binoculars.

2208 MST: returned to the 12" telescope. Viewed the globular clusters M9, M19, and M62, 102X, but they were still a little too low in the sky to image.

2230 MST: mounted the DSLR at prime focus + focal reducer, focused on Antares, and locked the primary mirror. 2238 MST: StarLock ON. Took these StarLock autoguided, 30 seconds, ISO 2500, White Balance 3570K images, of the three globular clusters:




2251 MST: Wi-Fi ON. Used SkySafari 5 Pro on the iPhone to GOTO Near Object Object (NEO) asteroid 2017 CS. This is a StarLock autoguided, 1 minute, ISO 6400, White Balance 3570K, image:

Got lucky to have included the galaxy NGC5267 in the field-of-view.

Then used SkySafari Pro to GOTO the star KIC 9832227 (GSC 3543-1211), which is predicted to go "nova" in a few years. Took this StarLock autoguided, 30 seconds, ISO 5000, White Balance 3570K, image showing the star field:


I attempted to ID the star, which should be near the center, but was not successful. Will have to wait for it to "blow".

2316 MST: StarLock OFF, Wi-Fi OFF. Removed the camera from the 12" telescope. 2324 MST: LX600 OFF.

2327 MST: terminated the 8th Kissing Bug of the night.

Mounted the D7200 DSLR on the SkyTracker Pro and polar aligned the tracker. Focused on the star Deneb using a lens Bahtinov Mask. Took this tracked f/5.3, 2 minutes, ISO 5000, FL 80mm, image of the North American Nebula (NGC7000):


Then aimed the DSLR at the core of our Milky Way Galaxy and took this tracked f/3.5, 2 minutes, ISO 5000, FL 18mm, image:
