I've seen plenty of ads for artifical star collimators. Sounds a lot more convenient and apparantly you dont need to wait for a clear night for steady viewing.
Any suggestions?

Hi Carl
I was put on to the Cats eye by Brendan and Grahame and I used a combination of the Cats eye Auto collimator and a Hotec Laser Collimator to get things close. The real improvement is then in the star testing as this is were all the effort pays off.
I have the artificial star but you need to set it up at about 30 -40 meters to get the best result. Persevere with the star testing but from my experience get a friend around to give you a hand as it's definately easier with 2 people.. unless you have arms like an indian death goddess
An alternative is the Tak collimation scope (very expensive) this is 2.7" and needs several adaptors to fit it to the RC (but worth every penny i'm told ) in the end.
hope this helps.
All the best
Paul
