Hi,

Hi,

With so many people collecting spectrum now, that's pretty much where we're heading. The eminent Czeck meteor astronomer Jiri Borovicka published a paper in 2016, "Representative meteor spectra..." (sorry not sure of the full title) based on many years of his work using spectra colllected via image intensifier and recorded on video tape.

The technology has moved on and even a basic system can exceed the pros now.

The situation has gone from a few (photographic) spectra per year to several per night with video based systems!

Bigger systems with institutional funding now have hundreds of cameras running! The shower meteors are quite well established but it's the sporadics that provide the surprises!. I've recorded several very interesting ones recently. With said technology the amateur is still on a par with the pros regarding sporadics.

cheers,

Bill
