Posted: 5 February 2024

Cloudy skies returned on Wednesday, 17 January 2024. With significant rain back in the forecasts, Saturday morning, 20 January, I put the Dome Cover ON. Sunday, 21 January, had rain (0.69") most of the day and night. Rain continued on Monday, 22 January (0.23"), and Tuesday, 23 January (0.33") and ended mid-morning Thursday, 24 January (0.04"). The forecast for Friday night, 26 January, was for a clear sky, but clouds began arriving mid-afternoon. Cloudy skies prevented observing through the end of January and into February. Rain (0.15") began late Thursday night, 1 February, and continued (0.66") on Friday, 2 February. Even had some thunder and a rainbow in the afternoon.

Attached the LiDAR Cover to the iPhone 15 Pro Max and mounted the iPhone on the 2" 5.5mm eyepiece using the Accuview 3-Axis Smartphone Adapter. Took two images of Jupiter using NightCap Camera (ISO 55, 1/60sec, and ISO 400, 1 second, both 1X lens). This is a composite of the two images showing Jupiter and the four moons. The Great Red Spot is visible just below center on the planet's disk.
