Total lunar eclipse - 27.7.2018 at 23.46 - 28.7.2018 at 00.36 Vesanto Observation number 75924

Visibility IV / V

Esko Lyytinen, Ursa (Etelä-Suomi)

I was on a boat watching and filming the eclipse. I was a little confused when, after careful lenses and the inclusion of binoculars, the main camera had split up and I had to pick it up just at the time when I thought it would appear and should have.

There was a perception that it takes a good time for the night to darken and the moon to rise higher before I get completely darkened. I would have tried to make it as visible as possible with my infrared daylight balloon camera as early as possible, but unfortunately I didn't get an unobstructed view of it from all over the place. I replaced the test by examining the visibility with different color channels of a normal color image. I attach almost the first red and green channel images converted to grayscale. Blue doesn’t show anything on the moon so I don’t put it on. Taken with a 28mm focal length lens. Canon EOS6D camera, unmodified. There are pictures of two and three.

I put the first normal picture with a 135mm lens about a minute after the end of the complete phase.

I still put 4,5,6 color channel images from that first image and they are in color.

Of course, you can do a similar "test" with your own color pictures of this.

Infrapunakokeilu olisikin ollut ihan mielenkiintoista nähdä, mutta se sitten ensi kerralla! Tuo ensimmäinen kuva on esteettisestikin hieno, ja mielestäni kaikkein näyttävin vaihe silmin havaittaessakin.
