Photometer


 

I've received an email from Tom Calderwood, who?is head of the AAVSO PEP section, saying that he has an Optec photometer available for use on bright stars, which could be used by a UK observer.

Tom says? ?"a prospective?observer needs either a cassegrain scope of at least 8 inches aperture
or a relatively short-tube refractor of at least 5 inches, equatorially?mounted and preferably with
GOTO. I can discuss other more specific?points with interested individuals".

If anyone is interested please contact me personally, not through the alert group, and I'll put you in touch with Tom.

Gary
