Just come in from looking at Mr Moonie through my XLT 120. Eyepiece was Delos 6mm, no filters. I saw some bright red markings on the walls of some craters - particularly Gassendi - and on that peak in the middle of Gassendi. It looked like it was a prism effect from the sun shining on the crater walls. Crystals?? Diamonds?? Or was it just a quirk of the XLT 120 glass or maybe refractions in atmosphere? Any ideas?
