Vendor for 6" f/6?

Hi all,

I want to build a 6" newt OTA for use on a small equatorial mount I have (Stellarvue M4, equivalent to old Orion Sky View Deluxe). I'm trying to pay close attention to weight issues in order to get away with it on this mount - aluminum tubing, helical focuser, etc...

Anyway, I can't find anyone who makes 6" f/6 mirrors. I'd love to use Discovery but does anyone know if they would accept custom orders?

Or does it sound like I might get away with a 6" f/8 on this mount anyway?

I know some of the high-end people (Royce, Mark Harry etc.) would take a custom order like this but a $500 mirror for this scope seems like overkill...I want to see if anything inexpensive is available first.

Thanks,

Mike

Since your not likely to find a 6 inch F6 mirror commercially available looks like you will have to grind and polish your own. Over the years I've managed to pick up several six inch blanks ranging is prices from $10.00 to $50.00 with about 40 hours of your time 20 hours to hog out and generate a sphere and 20 hours or so to generate the parabola you should be able to roll your own mirror and not have to be at the mercy of a vender or their prices.
