Recently on a very cold clear night I made an image of the moon using my C11 telescope. Because of very good seeing I was able to distinguish lots of details. In this image a comparison is made with images made from the Lunar Reconnaissance Orbiter which is in orbit around the moon. It’s nice …
This image taken on febr. 1 2012 can be used as a reference map for visual moon observations. All indicated structures should be visible with larger telescopes.
On the crater floor of Plato a lot of small craterlets can be seen. These form a perfect way to check the resolution of your telescope in combination with seeing conditions. On febr. 1 I had a perfect seeing and imaged the plato crater. On the image almost all possible craterlets from 1km and larger …
Goldschmidt is a large lunar crater of the variety commonly termed a walled plain. It lies in the northern part of the Moon’s near side, and appears oval in shape due to foreshortening. The rim is actually relatively circular, although the western rim is overlain by the prominent crater Anaxagoras. Nearly attached to the southeast …
Schroter’s Valley, frequently known by the Latinized name Vallis Schröteri, is a sinuous valley or rille on the surface of the near side of the Moon. It is located on a rise of continental ground, sometimes called the Aristarchus plateau, that is surrounded by the Oceanus Procellarum to the south and west and the Mare …
Tycho is a prominent lunar impact crater located in the southern lunar highlands, named after the Danish astronomer Tycho Brahe (1546-1601). To the south is the crater Street; to the east is Pictet, and to the north-northeast is Sasserides. The surface around Tycho is replete with craters of various sizes, many overlapping still older craters. …
This is a mosaic of the moon made on 01-02-2012. It’s the sharpest image of the moon I made until now. It consists of 48 images made with my C11 at f/10 and a DMK21-618 webcam. Separate images consist of movies of 1800 images each, of which 80% is used.
A lesser known sight in the nebula-rich constellation Orion, NGC 2174 can be found with binoculars near the head of the celestial hunter. About 6,400 light-years distant, the glowing cosmic cloud surrounds loose clusters of young stars. Covering an area larger than the full Moon on the sky, this stunning narrow band image adopts a …
