Worth Getting Collimated?
Hi all.
I have bought a second hand pair of 'Doctor 10x40 B apsheric's' here on BF last December. A lovely binocular, not at all popular, but in my humble opinion very good optically. My quibble: I was 'messing' today with them and saw that the objectives un-screw. Curiosity killed the cat, and hey presto, i opened a barrel of one of the objectives saw the inside and said: " what was that all about". Screwed it back in place and looked through it immediately - WHAM, what a sudden rush of blood to the head! My fore-head was hammering me with a sudden headache. I pulled 'em back about 4" from my head...(a tip told to me by a source on BF...) and took the shed roof as a guide line to see if i could get a 'straight line' view and not a 'Z' type jagged look - but, the latter was the case. They we're totally jagged out of collimation or alignment.
Does anyone know if these are worth getting re-collimated and possibly serviced? I paid only £100+ P&P to Ireland. They we're taken over from the famous Jena line of the then East german Co in the mid-ninties....(i may be corrected here) I'm nearly certain none of ye have used this model..
Comments and opinions REALLY appreciated 
They aren't porros are they? If so, it sounds like what happens when you fool around with the objectives and dis the combobulation rings at the same time! Actually they are called eccentric rings. If so, a competent binocular technician could recombobulate them.

I actually owned this binocular for a time in the early 90's and had the right telescope refuse to focus for no apparent reason. They were repaired under warranty (yep - I bought 'em new) but the repair folks volunteered that the binocular was notoriously fragile and that future repairs would be "costly". Other factors which you might consider are that the binocular is not phase coated (i.e., once repaired, you will still have at best soft images with little contrast) and the optical lens coatings are seriously dated. If they were mine, I would cut my losses and use the binocular to further your training as a future optical repairman.
