After a perfect day the sky was clear and the temperature was cold. I spent a good deal of time tweaking the collimation of the scope and setting up the laptop to communicate with the Ek Box. Dave Moorhouse went back to Kumeu to collect the 16 inch Binoculars. A good deal of people were there, but a little less than normal. During the day I planned a good observing run, a swag of unobserved Herschel II 400 objects and a few planetary nebulae, in the Ophiuchus and Scorpius region. Observations as follows; | ||

| Jupiter | Planet | 114x | Watched Jupiter all evening. Moments of excellent detail, but seeing was poor. Io (I) & Ganymede (III) and their shadows were transiting just before midnight. Watched both shadows enter the disk. Red spot also was very evident. |
Another excellent nights viewing. I sent up very close to the Waharau Hall to shelter from the occasional south-westerly gusts that were very cold. Used Skymap Pro v11 with good effect, with the computer mostly in-line with the eyepiece. Using the computer enabled me to speed through the planned Herschel II objects that I need to catch up with. 121 Objects logged tonight, an excellent effort!! So many object , that I cannot recall a stand-out object. Nice to get new objects logged and I am well on my way through the Herschel II list, only 180 to go (most of the 180 never rise from New Zealand). Jupiter was very good when the seeing gave those moments of crisp views. The 16” Binos were impressive to see Jupiter through, even when only using one eye. A double shadow transit was well underway at midnight. Saw Io’s and Ganymede’s shadow ingress the disc of Jupiter. Packed up just after midnight. Another 5+ hours at the scope. |
