Make yourself a light bucket for next spring and summer's viewing.
17.5 inch f /4.6 (80 inches), 1.5 inches thick with good coatings. The other number etched in the glass is 1843, but I do not know the optician that performed the work.
3 inch secondary with good coatings.
I think the glass is pyrex but cannot verify that for sure.
I would prefer to sell these mirrors as a unit, but would consider a reasonable offer for each one. Buyer pays shipping. Personal checks need to clear before shipping.
Thanks for looking.
