Hi,
Great videos!
Dashboard cameras are looking like the new tool for the mobile observer!
Bill.

Hi,
My name is Kouji Maeda observed in Miyazaki (Kyusyu ).
I captured the fireball and the spectrum.

I have observed low resolution meteor spectrum for seven years by the UFO system.
This is the one of the great spectrum.

Hi Kouji,
That is a fantastic result!
How many lines per mm does your grating have?
You have very good resolution.
Best regards,
Bill.

Dear Kouji,
I hope you have no objections but I used your image to produce a couple of plots.
I have used your name in the titles so feel free to copy and use the plots anywhere you like however please credit the production to "B. Ward. IMO."
With field curvature and saturation it was impossible to correct fully but the synthetic colour version looks great! There appear to be many Silicon lines present. A great fireball!
I hope you like the the images.
Best regards,
Bill.

Hi Kouji.
I use the same gratings on my video cameras.
You DSLR image is very good.
I have had no success so far with DSLR spectroscopy despite trying during several showers over the past years.
Perhaps my luck will change with this years Leonids!
Regards,
Bill.
