I first shot the moon with a monochrome camera with RGB filters. It turned out to be difficult to align the channels, because due to the rotation of the field the Moon managed to turn around a bit – halo on the craters climb out. For color photography of the moon, I will still use a color camera.

The Fujinon KF 8x32W binoculars came to my test. 8×32 format binoculars are considered the most versatile in combination of magnification / dimensions / weight parameters, suitable for daytime and astronomical observations. For ground objects at dusk, 8×32, of course, will be noticeably dimmer than 8×42 or 8×56, however, for long-term wear on the neck 8×32 will be more convenient. This is especially true for hunters, animal watchers and tourists.

I was very surprised that the Fujinon KF 8x32W has very few reviews. As it turned out, there are models that are very similar in characteristics and appearance to it – Sightron “Blue Sky” II 8×32, Kenko Ultra View EX OP 8×32 DH II, Vixen New Foresta HR 8×32 WP. Their case looks a little different, and also, most likely, a different coating, but there is a very high probability that optically they MAY BE similar to Fujinon KF 8x32W, and he himself is the “reincarnation” of the above binoculars.

I tested the ZWO ASI183 MC color camera on the moon. The main task was to highlight the color of the moon. I added saturation to the result of stacking without deconvolution, then converted it to the Lab system and used the stack without deconvolution converterd in monochrome as L-channel.
