brantuk Posted February 16, 2010 Share Posted February 16, 2010 You might have a collimation problem Ben. Is this the one from Argos? Googling nr67az just gets me a postcode in Norfolk. Do you have a more accurate model name/number? Link to comment Share on other sites More sharing options...
TopHouse Posted February 16, 2010 Share Posted February 16, 2010 I suspect he's transposed the numbers and it's this :-Buy National Geographic 76mm Newtonian Telescope. at Argos.co.uk - Your Online Shop for . Link to comment Share on other sites More sharing options...
david's dob Posted February 16, 2010 Share Posted February 16, 2010 definately does sound like Collimation, have you also checked the eyepeices for dirt ect.., and what eyepeice are you using. normally on the side of the eyepeice it said's 25mm ect?

brantuk Posted February 16, 2010 Share Posted February 16, 2010 Thanks TopHouse - yes that looks like it's likely to be the one. The toy shop as I suspected - but still useable with the right ep's and good collimation/setup. Link to comment Share on other sites More sharing options...
insomnia Posted February 16, 2010 Share Posted February 16, 2010 I'm intrigued by the 13x barlow that comes with it according to argos Link to comment Share on other sites More sharing options...
TopHouse Posted February 16, 2010 Share Posted February 16, 2010 It's a 3x really, same one they supply with the little refractor they also do. Link to comment Share on other sites More sharing options...
david's dob Posted February 16, 2010 Share Posted February 16, 2010 Even the first review states that it was way out of collimation, and the eyepeices could not reach the stated magnification, however as brantuk said the right Ep and good setup.
