Re: Help me build an American Optical frankenscope

"Actually I'm a little inclined to get a bunch of photography gels and make my own filters as Oliver illustrated, that way I can make them lots of different sizes and leave a tab sticking out and not feel like I have wasted a lot of money on filters I don't use." Yes.. The gel filters work very well...

If they are the same tube length and thread, they should fit and work.. And, probably not make enough difference to matter to the hobbyist...

Hi Billbilt, Just catching up on posts I haven't read yet and I fully agree with your sentiments regarding beginners being frightened away by technobabble, mostly from members that seem to be more interested in microscopes rather than the things they are designed to view. However I have read Primes...

Re: LEDs : Colour Rendering

LED'S ARE PERFECT FOR HOBBY USE.. THEY ONLY BECOME AN ISSUE WITH SNOBBISH, CRANKY FOLKS THAT WANT TO CLING TO THE OLD FASHIONED LIGHTING.. THEY ARE CHEAP, LOW VOLTAGE, ALMOST HEATLESS, AND LAST FOR YEARS....
