    For anyone interested in meteor spectroscopy there is a 1200 g/mm B&L 4
1/4" square reflection grating blazed for 5000A listed on eBay Item
#2531501237. (USA sales only)..David Airey of the BAA described the use of
such a grating for meteor spectroscopy in the BAA Journal 109, 4, 1999.
Instead of looking through the grating as one would with a transmission type
the camera looks down at the reflection grating with it imaging the sky into
the camera.  A little more difficult to set up but it works.
