| This page contains observing reports of 2010. Click pictures to enlarge them or click the name of a location for more information about the observing site, when available. The values as given for transparency, seeing and limiting magnitude are averages for a night. The maximum SQM value was measured towards the zenith and is not "corrected". Click the Excel icon to open a file with worked out observations or choose the notepad icon to open a textfile. By clicking the third icon a .obs file can be downloaded which can be imported in AstroPlanner V2. The icon on the right opens an overview of the positions of the observed objects. I recently started translating of all of my logged observations from Dutch to English. I expect this to take quite some time. More Excel and AstroPlanner icons will appear as I complete translation of more and more sessions. Once I have translated all observations I will translate session details too. Stay tuned. In the mean time, if you want to read more about my observations and at the same time feel like sharpening your Dutch language skills, please go here.        |

| From Thursday 1 until Saturday 10 July I was in France for a vacation of which part was dedicated to astronomy. I spent the nights observing when moonlight was not interfering too much. Also, I set up a camera every night for (timelapse)photography. |
 Saturday 3 July |
 Nights
are short this time of the year and tonight the Moon will interfere rather
soon after astronomical twilight ends. In total it will not be completely
dark for more than three quarters of an hour. Thankfully it will take a
while for the Moon to peak over the mountains in the east.In the afternoon I set up my equipment in the tent. The first two nights the telescope will be mounted in altazimuthal ("Alt/Az") to allow observing of objects close to the celestial pole. |
