Canon 10-30 IS collimation new
      #3190003 - 06/29/09 10:43 PM

I have a 4-year old 10-30 IS that is just about miraculous for terrestrial objects, but which displays much diffrent images of stars left and right, making them not-so-useful for night work.

I recently read a post that described near perfect performance from a 10-30 IS, and this has me wondering if one side of my unit is mis-collimated.

Can these binoculars be collimated in the field, or is this a factory return? Second question, will customer service even know what I am complaining about since this is essentially a horse-race viewing unit, and is not sold or advertised for astronomical use?

If this coma is just the nature of the beast, then I will quit worrying about it. But, if I can get pinpoint stars, I want them. IS is the difference between bliss and blasphemy.

Thanks for any thoughts or experiences.

Hi Kim,

I also have the Canon 10x30IS binocular. Considering the intricate workings on the inside, I personally would NOT try any adjustments in the field.

I would suggest sending them back to Canon for service, probably not the answer you wished to hear.

Best regards,
Dave.

I had a good sample 10x30 IS - stars were pinpoints almost to the edge.

Send them in for repairs (hopefully under warranty).

Thanks guys,

My local source will ship the unit to Canon and return it for $30.00. Canon CS will give me a free estimate, and then I'll decide how much I want to invest. I'm told that Canon works in the bino shop for $125.00 per hour. I guess it pays to figure these things out before the warranty expires.
