To Lookinglass Astronomical Products:

I am interested in two of your lightweight, cellular Pyrex mirror blanks. I have a few questions regarding the 20.5 and 24 inch hexagonal webbed mirror blanks:

20.5 inch hexagonal webbed mirror blank

1) Approximate shipping costs and delivery time to Norway

2) Does the hexagonal webbing allow for a Cassegrain central hole large than 6.5 cm diameter?

24 inch hexagonal webbed mirror blank

1) Approximate shipping costs and delivery time to Norway?

2) How large diameter Cassegrain central hole is possible?

3) The specifications of the 24 inch blank are not on you website. Are the thickness, web height and weight proportional to the 20.5 inch blank?

Many thanks and best regards,

Robert
