Moon pics recorded with the Toucam often show a small degree of colour which is destroyed when choosing Grey Tone in Photoshop and you are left with an un-natural dead-pan blue gray picture. Fiddling with Registax colour change has convinced me that a subtle sepia colouring is closer to what one sees when recording and improves the detail while providing artistic value to one's pictures. A well balanced composition is something I've always felt as being as important as good clear, sharp detail , if the finished picture is to be of interest.
What are the readers views?
To me the sepia tones you've used do look natural.
But everyone has their personal preferences and methods for processing.
Some push the colour processing to the extent that they bring out false colour, that can be an indication of mineral deposits, others like grey scale images of the moon. I take my moon images in colour with my little Canon camera, the only processing I do is a little sharpening if needed, jpeg artifact reduction and adjustment of midtones.
That's a very nice pic I agree it looks natural ... judging so far only from photos I've seen; my only telescopic viewing of the moon was bright white daytime views
