Collimation

Tonight I grabbed my 4" on EQ mount out. I haven't used it for a while. I noticed a thin blue line around the moon and the stars wouln't pin point for me. Is that a collimation issue? It wasn't dark enough to get the stars to "donut" properly in the eyepiece.

Thanks Bob. I haven't collimated this one for a long time as it's been sitting in my loungeroom unsed. I have a 10" dob that I use most of the time.

I'll try that and see if it sorts it out.

Whilst looking at the utube links I found this one which I thought was rather good.
