(meteorobs) Lyrids from Colorado

[catlin]

Wow. Many thanks for that Chris.

Do you think that I may be able to obtain just one picture of this year's
Lyrids to place on Aquarine my website?

It's quite a cultured space even if a be as so bold to say it myself.

www.aquarine.org.uk

Don't worry if they are all copyright etc. No problem.

Thanks for sharing your wondrous insight.

Clear skies - long (thinish) trains!

All trains are essentially infinitely thin, since they are narrower than the
angular resolution of the camera (or of our eyes). So the apparent thickness
in the image is a consequence of diffraction and the brightness of the
meteor. In fact, I use the thickness (the size of the head in any individual
frame) to estimate the magnitude when the brightness results in saturation
(which happens at about mag -4).
