Very close to Tringulum galaxy M33 we may spot a bright open cluster towards Perseus constellation. Its name is M34 and here it is a picture I took today through a remote 6 inch apochromatic refractor on New Mexico that shows colorful stars. Enjoy it!

The Moon highly saturated

Usually we see the Moon as in a gray scale picture, with no color details. Nevertheless the Moon has different hues depending on the chemical composition of the terrain. For example, Mare Tranquillitatis has a blue tone due to its titanium high density. Processing a Moon picture computationally, we may exaggerate its colors, giving high saturation to RGB colors. In the resulting image, Mare Tranquillitatis is the most blueish dark area. Equipment: Telescope Tanzutsu Catadioptric 114/1000.
