large primary

[smainsy (Stephen)]

Hey, i was hoping someone could point me in the right direction. I want to buy a large primary mirror and would like to know of some websites that sell them. Anything in the 20" would be nice. I plan on building my own to acompany my 10" in my arsenal. Thanks

Hi Stephen,

Have you thought about grinding your own?

Obsession Telescopes have 20" mirrors 'off the shelf' made by OMI and Galaxy Optics so long as you don't mind an F5.

There you go : 20" F5 off the shelf for $3300 USD
