Copernicus Home

I have a second page of pictures of Copernicus showing the crater at different magnifications on the same night.

Move your mouse over the picture to see the names of the various features.

Copernicus is a very young crater at less than 1,000 million years, and is a typical impact crater of this size.  It is 95 Km in diameter and its walls rise to 3,760 metres.  It has three central mountains, the highest 1,200 metres high.  The northern part of the floor is significantly smoother than the southern part.

Click on the first picture to see a larger picture of the area and a brief description of impact craters.

This is a general picture of Copernicus and its surroundings taken at lunar day 9.8.  The mountains at the top of the pictue are the Carpathians on the southern edge of Mare Imbium.  South is Mare Insularum which surrounds Reinhold.  The angle of the Sun is fairly low and brings out the detail surrounding Copernicus including the raised platform on which the crater sits.
Click on the picture to see a mosaic, taken the same night, of this with one covering Eritosthenes.
The scale markers are roughly 100 Km north and east.

Date and Time: 10th December 2005 20:18 UT
Camera: ToUcam 740K
Telescope: LX200 at prime focus
Capture: K3CCDTools. 50% gamma, 1/25", 35% gain, 328 frames
Processing: Registax. 64 frames stacked.  Wavelets 1 = 10, 2 = 5, histogram 0-200

This is a closer picture taken at about the same lunation but taken with a ToUcam attached to my ETX125 with a X2 lens attached on 30th March 2004, when the Moon was 9.1 days old.

Date and Time: 30th March 2004 20:58 UT
Camera: ToUcam 740K
Telescope: ETX125 with X2 lens
Capture: K3CCDTools. 50% gamma, 1/33", 15% gain, 364 frames
Processing: Registax. 214 frames stacked. Wavelet 1,2 = 10, wavelet 3 =5

This picture was taken with a ToUcam attached to my LX200 with a X2 lens attached on 7th October 2004, when the Moon was 22.8 days old.  The Sun was only about 10° above the western horizon so it was late afternoon there.   Even so there are few shadows because Copernicus is relatively shallow - less than 4 Km deep but 95 Km is diameter.  However the western slopes must be steeper than 10°.  
The arrows in the bottom left-hand corner represent approximately 50 Km north and east.

Date and Time: 7th October 2004 03:56 UT
Camera: ToUcam 740K
Telescope: LX200 with X2 lens
Capture: K3CCDTools. High gamma, 1/50", 36% gain, 392 frames
Processing: Registax. 254 frames stacked. Wavelet 1-3 = 10

This picture is very similar to the one above and is taken at the same phase (22.9 days).  It differs in two technical ways.  Firstly it is taken with a low gamma on the camers, which makes it somewhat darker, and secondly it has been sharpened with Focus Magic rather than RegiStax wavelets.  The larger scale results from the fact that the Moon was 27,600 Km (7%) closer to me when I took this picture compared to that above.  I've not provided a mouseover for this image; apart perhaps from scale markers there is nothing to add to the mouseover above.
The picture was taken on 22nd October 2008 when the Moon was 22.9 days old.

Date and Time: 22nd October 2008 05:53 UT
Camera: ToUcam 740K with Neodymium filter
Telescope: LX200 with X2 lens
Capture: K3CCDTools. Low gamma, 1/33", 59% gain, 643 frames
Processing: Registax. 282 frames stacked. Histogram 0-140 Wavelet 2 = 5
     Focus Magic 5,100

This is a wider picture taken with a ToUcam attached to my ETX125 on 15th July 2005, when the Moon was 8.5 days old.  It shows Copernicus in the lower left and Eratosthenes towards the top and the very southern end of the Apennine mountains at the very top. The picture was taken 50 minutes before sunset and was made in infra-red light.
The Sun was only just rising over Copernicus whose floor is still in darkness, but Eratosthenes is almost 9° east of Copernicus, so the Sun was 9° higher in the sky, and it is somewhat less deep than Copernicus and so its floor is almost fully illuminated.

Date and Time: 15th July 2005 19:26 UT
Camera: ToUcam 740K
Telescope: ETX125
Capture: K3CCDTools. 0% gamma, 1/25", 23% gain, 398 frames
Processing: Registax. 178 frames stacked. Wavelet 1-3 = 10, contrast 240, brightness -50
