Yip, but it’s only very slightly blue, and it’s not really a lake. Lunar photographers will often massively turn up the colour saturation to tease out very subtle differences in colour. You won’t see the difference with your eye, but the slight shades are really there, and reveal differences in geology all over the moon.
It’s known as Ina crater. It’s very small and probably of volcanic origin. You may have seen Astro-biscuit’s youtube video where he hunted it down.
After all the time i’ve spent looking at the moon i have never seen it although i didn’t watch it when it was obove us because i had troubleĀ reaching the eyepiece of the 12 inch dob and when i did it was abit bright on the eyes because i didn’t have a filter on it.
‘I just watched the youtube video Rob andĀ i now know why i haven’t seen the blue lake.’
Kind regards.
Stalin.
