The moon is not completely grey! There are subtle colour variations associated with certain surface formations. These differences arise from the different composition of the material lying on the surface. The many samples from the Apollo missions that were brought to Earth have provided proof.
The blue colouring of the dark mare and the reddish colour of the craters and highlands are striking. The mare consist of volcanic basalts that have a higher content of certain metals than the regolith of the highlands. The colours are therefore an indication of the metal content on the surface of the moon.
To compensate for the air turbulence, I took over 200 images and then stacked the best ones.

This is my first moonshot. And I am very glad with the result! The Olympus OM-D E-M1 was directly connected to my new (but old) 135/720mm telescope (focal projection). I took 10 shots at ISO 200 1/400sec. and stacked the best 5 with Registax6. The software runs on an imac under wine and it was a real learning curve to succeed. Finally a 16bit .png file was imported to Lightroom for a little CA correction, noise reduction and sharpening. N.B. astronomers call this lunar phase "first quarter".

Looking closely you will find some sunspots.

The Andromeda Galaxy is a spiral galaxy approximately 2.5 million light-years away from Earth.
Also visible are the two satellite galaxies M32 and M110 (right below).
The number of stars contained in the Andromeda Galaxy is estimated at one trillion, or roughly twice the number estimated for the Milky Way.
Andromeda is the nearest major galaxy to the Milky Way. It has a diameter of about 220,000 ly, making it the largest member of the Local Group.
The Milky Way and Andromeda galaxies are expected to collide in around 4.5 billion years, merging to form a giant elliptical galaxy.
