AASC pre name change to Astro Optical (pre '77)
Hi all,
Does anyone have any sales docs/catalogues or adds for Amateur Astronomers Supply company pre '77 (pre AOS)? I have some stuff from '77 - '93 (AOS) but nothing from the early years.
Id also like to know when they stopped using the wood mirror cell and changed to the Hall aluminium one (I think al their DK 12.5" were wood?) . I assume the trap door in the OTA went at the time they changed to the alloy cell if that rings a bell with anyone.
Roger
