WHAT on Earth IS This?

Now I know how you were able to identify Fullum's test report, without being told where it came from.

Outreach night at the library - success

Posted By john raymond

Reminder to myself: bring the second riser next time. Because Losmandy won’t make a single two-foot riser. Gotta buy em one foot at a time.

Shopping for a refractor Mount

Posted By john raymond

For a given weight, length, and diameter of a refractor, how do you calculate the minimum payload equatorial Mount for visual use? 

For refractors over 6” dia and over 8 feet long. 

We can calculate eclipses thousands of years in the future, but I haven’t seen my question addressed anywhere. 
Thanks

Best 10 collapsible dob?

Bob 
The Dobstuff is a good option. Dennis made a scope for me , he is pleasant to deal with.

I also recommend New Moon Telescopes Hybrid. http://newmoontelescopes.com/product-category/hybrid/

Ryan uses actual hardwood wood for the builds. They look like fine furniture. 

Add a good North American made mirror and you'll have a fine telescope.
