More Coolpix P900 Camera tests;
Posted: 1 June 2018
Thursday, 31 May 2018, was mostly clear but windy. The wind began dying down as sunset approached.
As I walked to the observatory I saw this Great Horned Lizard (taken with the Nikon Coolpix P900 digital camera):
Open: Thursday, 31 May 2018, 1841 MST
Conditions: Clear, breezy
After opening the observatory dome I saw this bunny just outside of the observatory (also taken with the P900):
I set up the P900 camera on the iOptron SkyTracker Pro for this night's astrophotography tests:
1903 MST: LX600 ON, StarLock OFF, High Precision OFF.
Viewed Venus, 102X and 163X.
Then saw some birds in a nearby tree (P900):
I stepped outside of the observatory and took a P900 photo (full zoom; cropped) of two of the domes at Mt Lemmon Observatory (11 miles away):
1928 MST: sunset. It was calm now.
Viewed Jupiter, 163X. The four Galilean Moons were visible.
1956 MST: viewed Jupiter using 12x50 binoculars. Three of the moons were visible; the 4th was too close to the planet's disk.
2009 MST: polar aligned the SkyTracker Pro for the night's P900 astrophotography tests. I did several test images for my upcoming Coolpix P900 review. 2056 MST: tests completed.
Returned to the observatory and began setting up for iPhone afocal imaging of Jupiter. I mounted the iPhone 8 Plus on the 1.25" 15mm eyepiece and did several single frame images and video recordings. I used the iPhone 8 Plus 1X and 2X lens for the images and videos. This afocal 163X + 2X lens is a stack of 923 video frames (30 seconds) taken with the iOS app NightCap Camera (ISO 80, 1/90sec):
The Great Red Spot is visible at the lower right.
2122 MST: southeastern sky brightening from the rising waning gibbous Moon. Ended imaging.
Viewed M9 (globular cluster), 163X and 102X. It was low in the sky and viewed through a tree.
Viewed Jupiter, 102X. The Great Red Spot was seen.
2132 MST: LX600 OFF.
Close: Thursday, 31 May 2018, 2144 MST
