Hi Michael and the others, ... Now here's an interesting thought. Reddening by the atmosphere vs. dimming by the atmosphere. Which one is more likely to win? ...
I was trying to keep the subject line short. It should read, "Counting Deep-Sky Objects with multiple catalog numbers". Recently I had added the remainder of...
... At least if one ignores the physiological aspect, reddening clearly wins because it increases at roughly double the rate of dimming. When you make...
