Yesterday there was a lot of Cirrus in the sky, full Moon was shining, it was quiet and comfortable outside (-5C but no wind) - a perfect winter night  I tried to observe lunar occultation at 21:59 EET but failed due to cloudness and very bright Moon. Soon after that I saw a weak halo and ran home for the camera. While the clouds were getting densier, the halo was getting brighter - it was easily visible (but without colours). The halo was 50-70% complete and the colours were visible in the photo (these images are edited to pull out more colours & brightness but it was good enough in the original images too) Images captured between 22:07 and 22:14 EET. First I tried 15sec@ISO400 but that gave poor results. So I tried longer exposures... 30sec@ISO200, processed  90sec@ISO200, processed  (Pollux above the Moon, Procyon to the right, Leo to the lower left) |

Well done Roman! that's a good quality near complete 22 degree Moon halo. Good colours present to. I can't decide which of the two images I like best but if forced to choose I would go with the first. Nice star-burst effect on the Moon. Your lens looks even wider than my 28mm. Nice shooting!

Thanks Martin. The original colours were more close to silver (grey) but after processing halo became twice as brighter in the image. I cannot understand, why it was evident to the naked eye but faint even on 30-60sec exposures? |

Great images Roman, reminds me of a noon day sun, very intense! As Martin mentioned, great starburst effect.

Thanks Richard ... reminds me of a noon day sun, very intense! ...
Of course it's bright - 1.5 minute exposure of the brightest Moon this year  Pity I cannot photograph the stars with long exposures - I need to hold the button with my hand otherwise the limit is 15sec |

Thanks for the comments and special thanks for the link John (jgs001). I must search the same thing in local inet-shops. |
