ATM illuminated finders

[pwillmin <pwillmin@dircon.co.uk>]

Dear ATM,
Greetings from Haslemere in the UK. I'm new to all this - ATM, news groups
etc. so please forgive any blunders!! I am interested in making two
telescopes, a reflector and a refractor.
I see that a program called 'Newt' is often mentioned and wonder whether
there is a Mac version available?
I have also seen mention of a 'HUD' type finder called a Telrad. Are there
similar finders around? I bought for £3.50 a delightful 'gizmo' the other
day, a personal protection light for clipping to your pocket when walking
along dark roads. The inside workings measure 45mm x 22mm x 10mm. It has a
small on/off button that sets a tiny but bright bulb flashing red once every
11/2 secs It's powered by a cadmium(?) battery about 20mm dia. The workings
weigh next to nothing at 6 grams . It seems to me that it would be possible
to have the light illuminating the edge of a piece of perspex with the face
engraved with either concentric circles as the Telrad or cross hairs as in a
gun sight and make a very light (sorry!) finder. Has anyone tried anything
similar?
It's a joy to come across such a disparate group of folk all enjoying a
common interest! Many thanks.
Regards, Pete Willmin
