Hi Pete,
Do you ever take a bad photo? Nice shots. Clear Skies Chuck Taylor Do you observe the moon?

I think he *does* take bad pictures but..and this is the cunning bit..he _never shows them to us_!

One of the great astrophotographers (I think it was Jack Newton) said that, for every good photo he took, he threw literally hundreds away.

Hi Pete, Do you ever take a bad photo? Nice shots. Oh yesss. I decided to mask the 'burn' on the 20s image. It didn't add much to the overall image and rather upset the composition of the pair. Another reason was the hair that crept into my optical path somewhere, appeared in the burn area and stood out like a sore thumb ;-) -- Pete Lawrence http://www.pbl33.co.uk Come and visit the "Lunar Parallax Demonstration Project" |

That's the first time that I see the Earthshine with such an "old" Moon. Yes I know - I thought that too. I've tried to capture Earthshine on an older Moon before but have failed miserably. I don't know the reason why it was so bright on the 25th. Stephen Tonkin mentions observing features on the Earth-lit side on that night with his 20x100 bins (See the thread "The night of 25/26 Feb."). -- Pete Lawrence http://www.pbl33.co.uk Come and visit the "Lunar Parallax Demonstration Project" |

http://homepage.ntlworld.com/p.lawre...Earthshine.jpg Are those colour images? On the 20s image, I detect a bluish hue to the Earthshine on the "dark" part, which perhaps is to be expected given the colour of out planet. Curious to know if that blue colour I'm seeing is "real" or some artifact. Martin -- M.A.Poyser Tel.: 07967 110890 Manchester, U.K. http://www.fleetie.demon.co.uk |

Apart from masking the burn and resampling to make them a more reasonable size for viewing, they are as nature gave them. -- Pete Lawrence http://www.pbl33.co.uk Come and visit the "Lunar Parallax Demonstration Project" |

Curious to know if that blue colour I'm seeing is "real" or some artifact. That raises an interesting question[1]: Are changes in the colour and intensity of earthshine as different parts of the earth (land/ocean) are doing most of the "shining"[2] detectable? Tim [1] Interesting to me, anyway [2] Mainly reflection of the sun of course, but might we detect man-made light - or at least how large a contribution might it have? I suspect undetectably tiny. -- Love is a travelator. |
