The Mars in opposition Session
Astrophoto Mars opposition 11/2020.
In October and November 2020, Mars in opposition was my very first astronomical object. I shot this photo with only manual techniques. I think the result is not that bad.
Mars size and apparent size
The distance between Earth and Mars was about 72.274.000 km on 4th Nov. 2020. On that day his apparent dimension was about 20 arc seconds. At his most distanced point in September 2021 Mars apparent dimension will be only about 3,5 arc seconds. In comaprison, the Full Moon got a size of 30 arc minutes or 1800 arc seconds.
