Perseids summary image 11/12 August (22 meteors)
Here's a summary of all trails imaged on the night before maximum. The
two b&w images were taken with a CCD camera fitted with a 28mm f/2.8 lens. The system gave me a field of view approximately 10 degrees across. The last image shows a pin-point meteor very close to the radiant position (as it should be of course!). The two central images in the second row show a glow through Taurus. I believe this is the Zodiacal Light but I'm currently seeking an expert's opinion on this one before I post up the full frame images. The summary file contains 22 meteor trails and is just over 1Mb in size. http://www.digitalsky.org.uk/meteors...07_summary.jpg -- Pete http://www.digitalsky.org.uk |

I've still to do a fine sweep of all the images taken but that'll have to wait for a bit. Total number of meteors imaged over two nights: 47. http://www.digitalsky.org.uk/meteors...07_summary.jpg -- Pete http://www.digitalsky.org.uk |

Perseids summary image Brilliant work yet again
Superb!
I only saw a few as I had only just finished having dinner at Rick Steins Sea Food Restaurant in Padstow. So made a quick dash across to the harbour to have a peek. Well done again Pete Cheers Andy Mr Andrew R Green B.Sc(Hons) FRAS.

I wish you had a grating to put on your camera, to get a few meteor spectra!? Ever thought about it? With your skill it would not take much. If you were closer I would give you a full ap grating for your camera. I got all packed up here then clouds moved in Sunday. Never fails. Jerry |

Excellent images Pete with a crafty leaning toward
composition. Where is the radiant point of the shower? I always thought it was in that little circlet of stars ESE of Mirfak near Lambda Perseii and NGC 1528 but when I traced back every bright Perseid I saw it seemed to coming fron a point between Eta and Gamma. Ben |

The radiant moves considerably throughout the activity period of the shower Ben. On the night of maximum draw a line from gamma to eta and turn left by 90 degrees. Move by the gamma-eta distance again and that's where it lies. -- Pete http://www.digitalsky.org.uk |

Thanks for the info, Pete. It seems like the radiant point
ought to migrate but I lost touch with it. Ben |
