Selenography: Copernicus

Tonight's 82% Moon, imaged with a Celestron 2000mm SCT Nexstar 8SE f/10 scope and a ZWO CMOS 174MC colour camera.

EQ6 Mount with Rowan belt drives.

 

Stacked in AutoStackert!3 with separate processing of luminosity and colour components.

Luminosity sharpened with wavelets in RegiStax6 and colour saturation boosted in Photoshop.

 

Seeing conditions were good.

 

Generally speaking, blue areas are rich in Titanium and brown rich in Iron.

 

Copernicus is a classical complex crater with terraced walls that drop 3.8km from rim to floor. It is 96km diameter. An extensive ray system of ejecta is well demonstrated in colour images.

 

Eratosthenes is the smaller complex crater above and to the right.
