I haven't imaged the moon for a while and with a break in the weather I made RGB and IR 642nm BP captures of 4 minutes per colour channel. This image was constructed from 3 panels, so a total imaging time of 48 minutes. For each colour channel I merged the 3 panels to end up with 4 monochrome images. These were carefully aligned in Photoshop, which was not straightforward. When the seeing isn't really good and it was only fair on this occasion, because of the way Autostakkert aligns and stitches together alignment boxes there can be a small amount of image distortion, since the alignment of each box for each colour channel may not be identical. Very close but not perfectly so. One can see this when blinking one colour channel on and off above another. I was able to compensate by using the size transform function in Photoshop and stretching ever so slightly some of the images to fit the green template image. Once this was done I did the RGB merge, then an RGB histogram alignment to get the colour right and then finally I used the IR image as Luminance with a 50% transparency. When the seeing is not good like this, then if you want a colour image it may be better to use a OSC camera with an ADC or stick to monochrome with a longer wavelength.

I didn't use a focal length reducer in order to get a wider FOV, however, this still gave an image scale of 0.3 arc secs per pixel, good for a 1 arc sec resolution limit, when the seeing is excellent.

This view is dominated at the terminator by the crater complex featuring craters Stöfler, Faraday, Fernelius & Maurolycus (see mouse over). These are in deep shadow and make for a dramatic reminder of ancient destructive forces. These craters when lit , like Maurolycus here, display traces of bright ray material from the crater Tycho to the west (left). Some of this ray material is visible extending to the east towards the limb.
