    Default 2" collimating tool



    I've seen two choices in the 2" sight tube/Cheshire combo market -- the Lightpipe and the Catseye.

    Anyone have a preference for one or the other?

    Catseye is renowned for being the most precise collimating tool. I myself use Cheshire - because of my Bird-Jones Celestron.

    I will probably go with the Catseye, but here's another question:

    The combination sight tube/Cheshire is less expensive than buying a sight tube and also buying a separate Cheshire. Is there any really, really good reason to buy these tools as separate items?

    Another to look at would be the Hotech 2" laser collimator...That, and a 2" collimation cap and you're set.

    I would not think so. As for a laser collimator - sources say that it is possible to adjust primary with the secondary noticeably askew in the way that the beam returns to bullseye. Do not know if it's true - I just prefer seeing and understanding rather than doing anything automatically. Laser is also useless with my Bird-Jones (what a chore!).

    I have not been able to find a 2" collimation cap anywhere on the market. I would prefer to buy one, since I'm not much of a fabricator.

    I also prefer the 2" cap to avoid the "slop" issue in my adapter.

    Where can I buy one?

    To be honest, I'm looking for one myself...but I've used one at a local star party.

    If someone would be so kind as to mention brand that would be great.

    Actually, since an autocollimator has a center hole, I wonder if it could serve double duty as a basic collimation cap? I don't own one, so I don't know.
