Aristarchus Plateau

14.1.2022 at 22.04 - Vantaa, Pähkinärinne (IV)
Paula Wirtanen, Ursa (Helsinki)

Before the cessation of the lunar observations, it was still necessary to outline the plateau of Aristarchus, half on the light side, with a terminator. I digested a photograph of the area, which, with stacking and a little sharpening, became more or less viewable. With regard to the drawing, the fingers did not really bend to a decent result, ie it remained mainly an attempt to draw. However: The Aristarchus Plateau (officially known as the Aristarchus Plateau) stood out clearly in a form resembling a peculiarly curved rectangle, and the comi-dimensional impression was clearly discernible. In...

Aristarchus

16.12.2021 at 22.30 - 23.25 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The company draws Aristarchus with its plateaus. Seeing was not as good as the top looked, and the terminator was perhaps already too far away. A has a diameter of 40 km and an age of about 450 million. years. It is the brightest crater of the Moon, it stands out well in the ground. The highlands stand out in Wanha's eyes as brick red in this light as well. On the radar, it is a bad reflector, meaning that there are no fist-sized and bigger boulders. Apparently it is covered with a few meters of volcanic ash, containing ferrous glass. The dark mantle of the plateau is older than the surrou...

Aristarchus

6.2.2020 at 21.40 - Hyvinkää (III)
Timo Inkinen, Ursa (Etelä-Suomi)

Aristarchus and Shröter’s Valley are an interesting area of the Moon, but this filming attempt was left a bit stubborn in resolution. Photographed / stacked on February 6, 2020 at 9:40 p.m. The following version was created in AutoStakkert! 3 1.5x drizzled and twisted in Photoshop. The brightest crater of the moon, Aristarkhus, glows bright in that middle and I intentionally left the rest of the areas darker. My homepage has a slightly larger preview image than this version.

Impressive Rilli Herodotus in connection with the crater. The Väisälä of the Finns can also be found in the picture.

Aristarchus

Aristarchus, Herodotus and Vallis Schröteri. The picture also shows the Finns' own Väisälä.

Aristarchus, Väisälä

13.10.2016 at 21.55 - Kauhava (III)
Oskari Syynimaa, Lakeuden Ursa

It might have been a bit bad to describe at such a high magnification, but I had to try Väisälä and the Aristarchus plateau when there was adequate lighting. A tired mosaic of four images. :) 23% of 3500 frames stacked / video. Larger image: https://www.flickr.com/photos/138130833@N03/30220464742

Aristarchus, Herodotus, Vallis Schröteri

21.1.2016 at 21.20 - Espoo
Jerry Jantunen, Ursa (Etelä-Suomi)

The plateau of Aristarchus was quite nicely visible in terms of lighting conditions. Seeing was just a bad average, but you can be quite satisfied with this winter's weather.

Väisälä

23.11.2015 at 22.49 - Nousiainen (III)
Lasse Ekblom

Almost in the middle of the picture is Finland's own Väisälä crater. The diameter of the destination is about 8.12 km. Also pictured: Vallis Schröteri, Aristarchus, Herodotus, Prinz, Rupes Toscanelli and Rimae Aristarchus. At the bottom left, a lonely mountain, Mons Herodotus, casts its shadow.
