Switched to the 2" 9mm 100° eyepiece and began an extended period of Jupiter observing, 271X.

There were some clouds low in the southeastern sky.

1937 MST: the Moon (one day prior to Full) was rising over the hill to the southeast.

Continued observing Jupiter, 271X. I planned to image it after the Great Red Spot became visible.

2138 MST: Kissing Bug #1 was accidently terminated. I had stepped on it.

2140 MST: clouds still low in the southeast.

2200 MST: the Great Red Spot was rotating into view, 271X. Unfortunately, seeing had deteriorated somewhat.

2209 MST: Kissing Bug #2 appeared (Kissing Bugs are 1" long and are bloodsuckers):


Kissing Bug was terminated.

2225 MST: the Great Red Spot was fully into view, 271X. Decided to image Jupiter before the seeing deteriorated further. Mounted the D850 DSLR for eyepiece projection 271X imaging.

2229 MST: Kissing Bug #3 was seen but he got away.

This is a stack of 214 video frames (DX 1080p 120fps 1/125sec ISO 2500):


Slewed to Saturn for this eyepiece projection 271X stack of 51 video frames (DX 1080p 60fps 1/60sec ISO 5000):


Wish the seeing had been better this night. Conditions are expected to worsen over the next several days as a Monsoon storm system approaches.

2255 MST: done imaging.

2258 MST: viewed Saturn at opposition, 271X and 102X. Seeing not very good.

2300 MST: LX600 OFF. Mars was rising over the hill to the southeast.
