(meteorobs) Large 20 degree Prisms for Meteor Spectroscopy

[Ed Majden]

Meteorobs group:
	Surplus Shed has some large BK-7 - 20 degree Anamorphic prisms for  
sale.  See: http://www.surplusshed.com/  Look under prisms for Item  
No: L91130.  If used with a long enough focal length lens, say 200mm  
or so on 4X5 film they should be useful for meteor spectroscopy.  I  
have not seen these but they may be worth a look.
