Collimation adjustment cost a killer

[anguswholesale]

Please refewr to this thread. I have asked question regarding the collimation and adjustment of binocualrs:

http://www.singastro.org/viewtopic.php?t=3101

Went down to astro scientific to do collimation. Was quoted between $250 to $280. Why is it so expensive when the binocualrs is not even nitrogen filled.

the binocualrs is a docter optics 30 x 80mm.

how much is the cost of collimation actually. for this price, i can even get a new binocualrs already.

hope to seek some other experiences.

many thanks

you have been warned :-)

is there any other place other than astro scientific where i can do the reparis and adjustments?

how about those camera equipment shops i see outside, or even the sim lim shops selling spotting scopes. will the prices be more reasonable?

thank you so much

I would avoid those shops selling cameras and spotting scopes. They usually do not do servicing.

Your next bet would be the shops selling 2nd hand cameras around the Peninsula Plaza area.

Failing which, you can either send it overseas or try to do it yourself.

How much did you pay for the 30x80? If not too much, you really should consider doing it yourself ....
btw, you should check out some of the articles on the net bout bino collimation. What we normally call collimation - by adjusting the prisms - is actually just prism re-alignment. Even if the image becomes "one" in the end, you might end up with "cat-eyes" in your exit pupil .. leading to light loss between 5%-20%. True collimation is by adjusting the objective lenses but normal binos do not allow this to be done by the consumer.

Just my 2 cents - some of the more experienced guys might wanna chime in ....
