Another excellent tutorial. Collimation is one of the things I have been dreading! I have read comments in other forums where attempts to collimate have rendered a telescope in a worse state than it was in before the attempt. I did not realise that the collimator itself actually needs collimating! Makes perfect sense when you think about it. So another mystery solved. This seems to be the only forum that tackles these issues in such an easy to understand way.

Thanks again.

Eddie

I 'think' the skywatcher is the same as the antares one but rebadged although I could be wrong.

This is a black art.

I've made the V block as per the tutorial and checked my Antares Laser Collimator, which I bought from RVO about a year ago, and sure enough the laser drew a circle. After about an hour of walking between the wall and the collimator in an attempt to adjust the laser I've only succeeded in making it worse! :crying:

Anyone got some advice or better still anyone know of a company who will do it for me?

Sit down, have a brew and a chill and try again lol, what you do is this, mark the tape on the wall where the dot is hitting, now an assistant would be good here to eyeball the dot on the wall, rotate the collimater until it is FURTHEST away from where you started, now what you want to do is adjust the screws until the red dot goes half way back to where you started, get your eyeballer to tell you if it's going in the right direction when you adjust.

Once you've hit the half way point, make a new dot on the wall where it's hitting and rotate again, repeat the above, doing this, the circle will get smaller and smaller.

Don't forget that blue tacking the jig to the table is an important step.
