New to this site, located near Puyallup WA, about 25 miles south of Seattle.
We're taking our Boy Scout Troop to Warm Springs OR (not far from Madras) for the eclipse event. I dug out a classic orange Celestron C90 to bring along. Have been reading up on filters, camera adapters and 'how-to'. We've ordered dozens of inexpensive viewing glasses for the Scouts. Seeing some photos of other folks rigs makes us look primitive ... but gotta start somewhere.
Still a bit confused / uncertain about what type of filter to use in front of the C90. Should it be something that friction fits inside the front of the tube ? Is a clamp over the outside of the tube better ? And it appears that using some form of dew shield / sun shield helps improve contrast with this basic scope.
We're also considering attaching a digital camera to the viewfinder and simply feeding the image to a laptop or larger screen device so that a group of viewers can watch simultaneously.
Secondary question: anyone familiar with the Australian made Univeral Wood Tripod with hydralok fluid head ? I'm trying to learn how it works. It uses thumb turn screws to tighten the vertical and horizontal movement. The vertical appears to be worn or misadjusted ... as the tightening screw bottoms out and it fails to 'lock' the head from further movement.
Thoughts ? Suggestions ? Recommendations ?
Thanks to all who provide information.
