I got my orion skyquest XT6 telescope from craigslist and on first good day of viewing I was able to see moon craters and saturn but even though I would see the moon in cross hair intersection of finder scope I will have to literally spend 1-2 mins trying to bring it in the main eyepiece. And man I was frustrated as moon is still big but saturn took me almost 5 mins to bring it in eyepiece. Something was not right and I remembered the owner had said to collimate the telescope. So I used this youtube video http://www.youtube.com/watch?v=YAVGcGEBmCE to collimate the telescope next day and again in the night same frustration something wasnt right.
So I remembered that in order to bring it home I had to disassemble the finder scope, tube and base in order to transfer it safely in my car and when putting it back I had tightened some screws on the finder scope and voila that was it. I read the manual it seems that as shown in the image the finder scope mirror need to be aligned to be in parallel to the main mirror in the scope. Thos two black screws in the image are used to move the scope left and right and towards and away from the scope. So I took the scope out in the day light and pointed it towards the street and put the 25mm eyepiece in the main scope. then I saw the top of a house in the finder scope and then in eyepiece. I kept tweaking the screws till I can see the exact object in finder scope cross hair intersection in the main eyepiece. I repeated the same process with 10mm eyepiece.
And boy in the night I could locate the saturn or moon in finder scope cross hair and then it was dead centre in the main scope.
Next task is to see Jupiter and mars.
