Following are just a few results from the lunar imaging sessions at the end of October. The images below are from the night of October 27th, and were acquired in not so good seeing conditions (4-6/10). Still they present some interesting information regarding some of the features.

The imaging setup: 355mm F/5 homemade Newtonian. ASI120MM-S camera. The rest of the details will be presented for each image.

The first image is a four-panel mosaic, showing the South-Eastern limb, with crater Neper (left) and Mare Smythii dominating the view on the terminator. This mosaic was acquired at F/20 and in red light using a Baader Red filter.

The image above was acquired at F/25 with RGB filters, with the luminance selected from the red filter data.

To compare the normal view through the red-filter to the color version, view the image below. The RGB image definitely shows a great difference in the distribution of mineral/material deposits at the lunar surface, impossible to truly appreciate in the monochrome data.

Despite the not very good seeing conditions, the information extracted from the color view of Copernicus is highly interesting, and perhaps I shall talk about it a bit more in a future post.
