Sent: Wednesday, March 23, 2005 14:55:21 From: Hugh Series (firstname.lastname@example.org) Here's a very simple, very cheap design for a finder which works well for that initial alignment when you're wondering if the star you can see in the finderscope (in my case a Meade 8x25 which was supplied with the scope) is really Polaris, or whatever you're sighting on. Cut a 7" long piece of L-section timber moulding. Each side of the L should be about 1" in length. Sizes are not at all critical. Screw two metal eye hooks about 0.4" in diameter just within each end of the ridge of the wood, sticking up in the air. Mount the device using 2 rubber bands on the ETX, eyes upwards, inside angle of the wood downwards on the barrel of the OTA. That's it! The shape of the wood automatically aligns itself along the length of the scope (it's sensible just to jiggle it a little to make sure it's lying properly flat). It helps to paint the eye hooks white for better visibility at night. You may have to align the eyes (vertically by screwing/unscrewing them a little, horizontally by bending them sideways with pliers), but this only has to be done once. It's not accurate enough to replace the finder, but it does help enormously for checking that you are looking at the right star in the finder.
Thanks for a great site. Happy viewing. Hugh
