|
Took these on Saturday 20 November 2004 at 1800h UT. Weather was freezing cold (-5°C) and there was a small amount of high level hazy cloud (this stabilised seeing however). Pictures taken afocally (using an eyepiece mount) through a 4.5" reflector using a 32mm Plossl with 2.5x Barlow eyepiece. Nikon Coolpix 5700 settings 0.5 seconds, f/4.2, ISO 200, fl=71.2mm. The images were processed using Adobe Photoshop CS. Note the crater called Conon in the 5th and 6th images. Some facts taken from Virtual Moon Atlas (Expert Version 2.0 2003-10-25) are: Copernician crater (from -1.1 billion years to present). 22x22km, 2320m high. Isolated circular formation situated in Montes Apenninus. Pretty steep slopes with high walls. Flat floor with central hill. Best observed at 1st Quarter or 6 days after Full Moon with mimimum instrument a 50mm refractor. Longitude: 2.0°E, Latitude: 21.6°N, Quadrant: North-East. Detailed Name: Conon of Samos - 4th Century Greek mathematician and astronomer, born in Greece at Samos in 300 BC. Friend of Archimede. Author of the constellation "Hair of Bernice" (Coma Bernices). Author of seven books devoted to astronomy. |

This image shows Moretus with its 2700m central mountain at the top centre of the image. Gruemberger A is just to the bottom right of it. In shadow below them is Clavius with Maginus bottom left of it. Tycho is the deep circular crater at the bottom right.
This image shows Tycho at the top right. The cluster of three to its left are Huggins, Nasireddin, and Miller. The deep crater centre right is Guaricus.
One of my favourites of this series. Rupus Recta (The Straight Wall), one of the most famous lunar faults, lies next to Birt and Thebit. Arzachel with its central 1500m high mountain and tiny crater next to it lies left of centre. Alpetragius is just below it to the right.
This shows the walled plain of Ptolemaeus at the upper left with the craterlet Ammonius inside it. The crater Herschel is immediately below the plain.
Another of my favourites. The large, deep, circular crater Eratosthenes lies at the right of Montes Apenninus (Appennine Mountains). The very flat region above this crater is a bay called Sinus Aestuum. Some of the very large mountains of the range are easy to pick out, such as, Montes Wolff, Mons Ampere, Mons Huygens, Mons Bradley, and others. The small crater Conon stands out in the lower left of this image.
This one shows the remainder of the mountain range.
Another of my favourites. The crater Aristillus in the centre has three mountains of 900m height in its centre. Note the rays extending out from all around it. The large flat-floored crater to its upper right is Archimedes. The small group of mountains just below it is called Montes Spitzbergen.
The predominant crater in this one is Plato, another flat-floored crater with very steep slopes. The mountain range running perpindicular to it is Montes Alpes with the pronounced valley, Vallis Alpes, running across it.
The final one in this series shows Plato to the top right. The crater in the centre is Timaeus. Hope you have enjoyed these views.
