Diana Juncher, it is nice to see a woman posting pictures here! I don't know Morse code, but I suppose you have written Vega's name in Morse code in the sky!
Fabiomassimo Castelluzzo and Stefano Conti, it is interesting to see your image of NGC 2841, particularly in view of the fact that it was APOD here just a few days ago. The galaxy looks very red in your picture.
Stéphane, I love your picture of Orion over Temple V. The composition is delightful, the cloud-flecked sky looks interesting, and I love the blue halo around Sirius!
Richard Yandrick, I'm bewildered by planetary nebulae because I don't understand their colors, but you picture looks very true-color and very interesting, so thanks!
ftherrmann, that animation showing the expansion of M1 over 72 years is hugely interesting. I wonder, however, if the film that was used to photograph M1 back in 1939 had the sensitivity to red Ha light that black and white film has today. It could be that the expansion hasn't been quite so great as it appears to be, but that modern film or CCD chips simply "sees" the red outer filaments of M1 better than the photographic plates of yore managed to do.
