Thankyou, thankyou, thankyou Mark - you are a gentlemen and a scholar
i just bought a pair of the same Andrews badged 20x80 triplets (excellent service- very pleasant experience I must say! - NO waiting 4 months - [just a week]
like some dealers unfortunately have a habit of doing) I havent used 'em at night yet - but i can tell their very good in daylight already - they are superbly light - i really like them for what i want them for - bright comets. And at that price how can you go wrong?.
I'm not terribly put off by slight out of collimation - my mate bazz'z old 70's german 20x80's got so out of alignment (or something?) once that stars were triangles - but when looking at a gorgeous bright comet at the time - it made no lick of difference to the view of the comet! it was still awesome!! weird!! but having said that I would still like to be able to collimate them myself - so thanks for the advice so far, that seems to be enough info (also using that oberwerk page as a guide).
But if you could by chance ever find the time to put together a pictorial step by step 'how to' collimate these particular binos - I think you would be EVEN more popular than you already are - if thats possible? especially seeing their are so many owners of this excellent 'bang for your buck' model on the foruml! its a big ask I know - i understand if you cant, no problem
btw an Adelaide astro/optical biz - i won't mention - charge up to $80 to collimate a pair of binos.
