Flat for testing

[cs1cjc]

We have friends who live about 1km away in of sight and they will, I am sure, be willing to host a flat mirror.  I got prices for a small flat from:

Orion Optics UK (elliptical): £42+VAT+carriage;

Antares (elliptical): $49.99+carriage;

Surplus shed (round): $20+carriage.

Of course, I will go for the last of these.  I shall also order optical bits to make an bath interferometer, sometime or perhaps never...

Sounds like an interesting project

Isn't the last one cheaper, because it isn't aluminised so presumably you would need to factor that cost in as well?

I should have read more closely!  I would definitely want a finished one.  However his project is now on hold, while I work on my 350mm dobsonian.

Many thanks
