look at those colours!

Showed Rhonda one of the quick shots of NGC 6520. She thought it very nice. "I like the little circle of stars near the bottom." I liked the colours. I said I particularly like the "sky blue, mango, wedding dress white, smalt, banana, and apricot" coloured stars...


She noted all the stars had colour fringing. Yes, indeed. My polar alignment error, poor focus, low elevation, lots of air masses, bad seeing, and not guided.
