collimation question

[mirak]

Is it better to use the collimation cap or a laser collimation device? I get two very different results with each. <br />The laser device has some play in the eyepiece holder so it seams the good old fashioned collimation cap is better.<br /><br />I have a Orion Intelliscope XT 10. <br /><br />Thank you, Paul

Well, IMO you're half right. <img src="/images/icons/wink.gif" /> Lasers have a tendency to wobble in the eyepiece holder, because of their length (unless you have a compression type fitting). I would reccomend the Orion Chesire-crosshair sight tube to align your secondary mirror. Then use the collimation cap to align your primary mirror. That's what I do, and I have the XT-8. <div class="Discussion_UserSignature"> <p><font size="4"><strong></strong></font></p> </div>
