Recommend a Cheshire Collimator

[Gmx76]

Hi

Think it's time I collimated my scope (Starquest 130P, 1.25 inch focuser). Looks like a Cheshire is probably the best option from what I can work out.

Would this be any good?

or am I better off paying a bit more and getting the longer one from FLO? (and if so, whats the difference between the long and short)

Hi Greg, that is all I use for my 12 inch Dob and follow up with a star test to finish off. Works well for me.

Great thanks will give it a go. Can you recommend any links with simple instructions on how to use it?

Thanks, if I buy the ebay one mentioned above do I also need a collimation cap?

No. The Cheshire will act as a collimation cap.

Adding to what Pixies has said - as the model you have chosen is the short version it can be used as a collimation cap. With the longer versions it would obstruct your ability to see all the way to the mirror clips, hence need a separate collimation cap (if it doesnt have the detachable kind)
