What is standard?

Posted By David Williams
Michael,
Its a Nova and it is stated in the documentation as 79.5. But as we all know proof is in the stars. Thanks for the formula, it may take a few minutes to sink in my thick head!

Carbon Fiber....How do I do it??

Posted By David Williams
I would find a tube of the correct size and use it as a male mold. Lay up half at the time with parting plates at the 50% line. Do the first half, remove the plates then prep for the second layup. That will create a two part mold that will create the surface finish on the outside of the part. That how I did my carbon 10" with a 12" tube. Look for my prior post and you can see some pictures. If you want a set of 12" X 12" carbon tubes I already have a extra set.

Aluminum tube - "Au Naturel" ?

Posted By David Williams
Don't under estimate the work required to polish the tube. It probably 10 times the work painting is. As for not getting hot. Find your local airport and look for some planes with polished aluminum trim. Now flop your favorite focus fingers down on it. When you get over screaming and speaking rudely, think white paint. Hard to beat for a lot of reasons. shocked

Meade Deep Sky Imager / Any comments?

Posted By David Williams
Gee guys I don't know but I expect if Meade follows its history you will be lucky to get anything before Xmas. For what its worth I was on the LX200GPS list from before the Oct. 2001 release date.If I remimber correctly it was Febuary 2002 before anyone got one. I got mine in June. Then two months later they cut prices and had eyepiece specials. I felt ripped.I wouldn't mind trying one myself but I still have a few reservations abot jumping too soon on new products.

Gelcoat

Posted By David Williams
If you have any concerns on recoating just sand and clean the surface with alcohol. Some solvents may attack the gelcoat. Alcohol should be fine. I work with aviation grade epoxies and avoid the polyester type materials so I may not be the must qualified on "boat" materials.
