Thank you, will try this as well. As is my luck, every night has been cloudy so far - time we got rid of this blocking high pressure system.

John, thank you for your response and the two links, very much appreciated. As you say the Opticron adjusting screws are in the same location. I'll give it a go tonight.

Hello, With the darkening nights I retrieved my Opticron Oregon 15 x 70 binoculars from their safe summer storage (top of bookcase). Alas I am now seeing double stars and planets (the moon is fine and also distant views during daylight) which I understand is a collimation issue. Searching questions have been asked and no-ones admitting to dropping them/rough handling during their bookcase perching. I have contacted Opticron who are quoting £50 plus . I'm hesitant to pay that (I live north Of The Highland Line so additional postage can be added) in case my pair are prone to collimation problems. My question is has anyone carried out collimation on Opticron 15 x 70 and can tell me where the adjusting screws are (the entire body is covered in rubber). I have no problems havng a go, at the moment they are no good for astronomy, unless I cover up one lens (then I've got a telescope). Any guidance would be appreciated.
