i'd have to agee with what's been said about the andrews cheshire. the wires are fairly difficult to see, even more so if you're collimating indoors. I found when i collimated outside in the sunshine it was alot easier. But i find myself doing wired things wiht a torch to get them to show up indoors. But.. it should be easier than it is. but it does the job. Collimating the primary is dead easy with the cheshire though(or maybe i'm not doing it right
) casue u just line up the centre spot and the reflection of the cheshire... but yeah.. just need to make up a sight tube for the secondary.
