1814 MST: LX600 ON, StarLock OFF, High Precision OFF.

Viewed Venus, 102X and 443X.

Attached my prototype LiDAR cover to the iPhone 13 Pro Max and mounted the phone on the 5.5mm eyepiece using the Levenhuk adapter.

Took these afocal 443X images of Venus using the 1X and 3X lenses.

NightCap Camera (ISO 100, 1/400sec, 1X lens).

NightCap Camera (ISO 250, 1/450sec, 3X lens).

Viewed Venus, Saturn, Jupiter, 443X.

Then did some lunar observing, 443X. During brief moments of steady seeing the views were awesome.

Viewed the Moon, 49X. Nice view.

With the LiDAR cover still on the iPhone, I mounted the iPhone on the 50mm eyepiece. Took this afocal 49X image of the Moon using NightCap Camera (ISO 34, 1/5900sec, 1X lens).


I plan to use this configuration for next week's near Total Lunar Eclipse.

At 49X, the Moon was very bright projected onto the observatory dome, as seen in this handheld iPhone 13 Pro Max photo taken with the Camera app (Night Mode, 3 seconds, 1X lens). The star Capella is just to the right of the dome.


Viewed the Moon, 102X.

This handheld iPhone 13 Pro Max photo taken with the Camera app (Night Mode, 10 seconds, 1X lens) shows the Moon projected onto the observatory dome at 102X. The constellation of Perseus is at the upper right and with M45 (the Pleiades) near the right edge.
