Many years ago (about 31 I think), I had just mounted my 10" Newtonian on a trailer and Doug & Bonnie McCombs and I went out to Simpson Springs between Christmas and New Years to photograph a Lunar eclipse. This was in the days of hypered film. As this would be the telescopes maiden trip on the trailer I was careful to use Locktite on all of the screws, nuts & bolts. We arrived just at dusk and we started to get ready. I carefully aligned the trailer with North and then removed the blue cover. It had snowed a few days before but there was only a thin crust of snow left on the ground. I had covered the ends of the OTA with some cloth covers to keep out dust. Standing at the front of the OTA I removed the front dust cover. Curiously some silver flakes settled to the ground in front of me. I thought it strange that snow had gotten into the OTA. So I looked in to see if there was any more snow. Gently rocking about half way down the tube was the primary mirror on its side. Looking further I found that the secondary was way out of alignment and seemed to actually be tilted. At the end of the tube was the mirror cell. It seems that in my haste I forgot to use Locktite on one of the three mirror clips. The bumpy ride to Simpson Springs loosened this clip and allowed the primary mirror to come out of its cell. I suspect that the last 10 miles of the road caused the mirror to bounce back and forth between the mirror cell and the secondary. Well that was along time ago and the original secondary and primary had to be replaced. They were both made by Coulter Optical and were of fair quality. Since then I have replaced both of these again with the last mirror done by Steve Dodds. If you ever get to the Bryce Canyon Astronomy Festival stop by and I can show you the cracks in the side of the OTA where the original primary mirror finally came to rest. I suspect that everyone that ventures out to a remote site has a similar story to Joe's & mine. Jerry Foote ScopeCraft, Inc. 4175 E. Red Cliffs Dr. Kanab, UT 84741 435-899-1255 jfoote@scopecraft.com
