Concentric circles on stars


Recommended Posts

If i understand correctly then when you put a star out of focus then you are supposed to see even circles... when i zoom out all i see is the star getting bigger and lots of dots on it, no circles or rings

Is this a collimation issue or eyepiece? Im using the 2 i got with my scope

Thanks for any insight :)

(Outside atm there goes my night vision)

sounds like rubbish seeing - my scope is collimated as far as I can tell and yet I've never been able to get a star test that differs from what you describe.

Is what you are seeing the same as the "atmospheric turbulence" diagram near the bottom of this link?

If so, don't sweat it - you live in the UK!
