Perseids last night

Despite quite a bit of cloud last night was pretty good from Chelmsford. On two cameras I picked up 287 Perseids, 16 sporadics and assorted other showers for a total of 350 events. The brightest was this very nice Perseid seen at 00:10. My images from last night are here and a video of the best ones is here.

Perseids Last Night (this morning)

We struggled on and off with cloud in North Yorkshire but I picked up a few and in particular this lovely coloured one.

Perseids last night

Was out last night Perseid meteor spotting. Saw quite a few then left the camera (Canon 550D, 28mm lens) running taking 20 second images. Collected 600 images (!), of which 13 showed meteors, 3 of them quite bright. Here is one of them near the M31 galaxy.

It's been pretty cloudy here in Brum, but I did have just over an hour of broken cloud after midnight on the morning of the 12th.  I was though at the eyepiece, but did catch a few by chance and out of the corner of my eye.  If it had been clear I would have done a proper visual watch.  Oh well...

Perseid image

Nick, Re. the very bright meteor image - one way you can do photometry on the image to measure its brightness is to calibrate the degree of attenuation in the lens system of the internal reflection, which can be seen diametrically opposite a bright source across from the optical axis. See the secondary reflected image of the meteor towards the bottom of the frame. Try imaging a bright planet so you can integrate the light of the secondary image of it. Then image a starfield and calibrate the zeropoint of the direct image. You can then determine the equivalent brightness of he secondary image and therefore the attenuation factor in the lens.
