Temperature: 84°F
Session: 1243
Conditions: Mostly clear

12" f/8 LX600 w/StarLock

There were some clouds in the southern sky.

1842 MST: LX600 ON, StarLock OFF, High Precision OFF.

Viewed Venus, 102X. Good gibbous phase visible.

Mounted the D850 DSLR at prime focus + 2X PowerMate. Did some Venus imaging. Tested the newest ShutterBoss III wireless remote replacement received from Vello. The previous remotes had all experienced random triggering. This new one had shown no random triggering during my initial daytime tests.

This is Venus (single image, cropped), 1/400sec, ISO 100:


1929 MST: sunset.

Slewed to Jupiter. The clouds were still in the southern sky and near Jupiter.

Took this single image (cropped) of Jupiter, prime focus + 2X PowerMate, 1/100sec, ISO 800:


The Great Red Spot is visible at the right limb.

This (cropped) image shows the four Galilean Moons and the Great Red Spot (prime focus + 2X PowerMate, 1/10sec, ISO 800):


The ShutterBoss remote had no random triggers this session.

Viewed Jupiter, 102X and 271X.

Due to the clouds, which were increasing, and an early commitment the following morning, I decided to end the session.

1948 MST: LX600 OFF.

Close: Friday, 1 June 2018, 2000 MST
Temperature: 78°F
Session Length: 1h 25m
Conditions: Partly cloudy

I have posted my review of the Nikon Coolpix P900 digital camera.
