In your article you mention a book about building truss scopes saying:

 

"I suspect that one of the most read guides on building truss Dobs (which was co-written by a major vendor, after all)". 

 

I am wondering which book you are referring to?

The Dobsonian Telescope.

That article makes me want a 16" mirror now. But I know I can't move it and don't want the ladder. I would need it to be a Danny style truss and f3.5 or so. Maybe I will some day. It need not be diffraction limited. It just needs to be smoothed of pits and cracks. 200x is all I need.

I truly enjoyed your very interesting article, building a 16 inch telescope. You remind me of John Dobson--building quality reflectors with inexpensive materials, coming in with minimal cost. You have a passion for astronomy and it shows through in your writing about this project. You are a fine young man. People like you give me hope for our country.

If it's not even diffraction-limited, you're not just losing resolution. You're outright losing aperture.

Congratulations, Zane! Your Dobsonian build overview will undoubtedly help and inspire many budding and seasoned ATM'ers alike.

 

Thanks for keeping this wonderful pastime alive! Great job, young man!

 

 

Thanks again! ...and Clear Skies, Forever!
