1928 MST: viewed the planet Mercury, 102X and 443X. Half-phase nicely visible.

Then relaxed on the observatory patio bench while waiting for the sky to get a little darker.

Mounted the iPhone 11 Pro Max on the 30mm eyepiece for this afocal 81X image taken with NightCap Camera (ISO 32, 1/1500sec, 1X lens).


I then did lunar observing using the Explore Scientific 100° field-of-view (FOV) eyepieces I have received for a review to be initially published in Astronomy Technology Today magazine. I also used the Explore Scientific 9mm 100° FOV eyepiece that I purchased in 2012.

This handheld iPhone photo of the northern region of the Moon was taken through the 9mm 100° eyepiece, afocal 271X, NightCap Camera (ISO 100, 1/120sec, 1X lens).


This handheld iPhone photo the craters Theophilus, Cyrillus, and Catharina was taken through the 5.5mm 100° eyepiece, afocal 443X, NightCap Camera (ISO 200, 1/60sec, 1X lens).


After completing my lunar observations, I viewed M104 (Sombrero Galaxy). I mounted the iPhone on the 1.25" 15mm eyepiece for this StarLock autoguided, afocal 163X image of M104 taken with NightCap Camera (Long Exposure, Light Boost, ISO 12500, 1sec, 1 minute exposure, 1X lens).


M13 (the Great Globular Cluster in Hercules), StarLock autoguided, afocal 163X, NightCap Camera (Long Exposure, Light Boost, ISO 8000, 1sec, 1 minute exposure, 1X lens).


2056 MST: Kissing Bug #4 terminated.

Viewed M13, 102X.

2100 MST: LX600 OFF.

Kissing Bug #5 terminated, not by me but by a dome wheel as I rotated the dome.
