50% LRGB Lunar X and V Moon


A semi-manual image of the 50% moon on 1st June 2017 taken with my Esprit 150.  Whilst my DSO imaging set up was waiting for the moon to increase its angular distance from my selected DSO target, I took the opportunity to acquire some semi-manual images.  I decided on an LRGB strategy since I wanted detail and colour contrast, so took 20 images per filter that where subsequently calibrated and stacked in RegiStar.

I then followed my normal DSO processing workflow, sharpening the Lum component and boosting colour on the RGB composite.

After I had finished processing the image, I noticed that, by accident, I had also managed to capture the so called Lunar X and V's - optical illusions that result in "X" or "V" shapes on the moon's surface.  These are visible in transition region between the light and dark regions.
