Photos of the Moon - November 20, 2018
November 20, 2018 (1) | November 20, 2018 (2) | November 20, 2018 (3) | Comparison of the Photos | Conclusions
On this page I present photos of the moon that I took on November 20, 2018 and that I edited afterwards. I used my Omegon PS 72/432 refractor on the Sky-Watcher AZ Pronto mount. I used my 32 mm DigiScope eyepiece with T-Mount and a 3 x focal extender, resulting in a magnification of 40.5 x. My camera was the Sony RX100 M4, which I screwed firmly to the 32 mm eyepiece (projection method) or held to the eyepiece (1:50 method). I exposed automatically, manually set the distance to infinity, and adjusted the sharpness with the telescope.
I wanted to find out how the different conditions affected the photo results and how the moon changes in detail within a few hours.
Note: The following photos are oriented in a way that they correspond to the normal visual impression.

Conclusions
These photo series were taken on November 20, 2018 shortly before 19 o'clock, shortly after 20:30 o'clock and shortly before 22 o'clock (the EXIF data are still on summer time...), so they cover a period of about 3 hours. In this time, the rotation of the moon is evident, but I could not find any significant differences in the shadows, probably because there did not happen much at the terminator on that day.
If you post-process the photos, as you can see them here, the differences between the series, especially to the one with the wet eyepiece, are not that evident. But the final series shows, at least, the most contrast because there was nor dew and the moon was so bright. You can see this especially in the original photos.
The sharpness of the photos varies between and within the series, probably due to poor focusing and air turbulence.
