hello rustigsmed,
You might want to check out astrosystems for their other collimation stuff as well.
"Special, get both the 2" LightPipe/SightTube and 2" Autocollimator for $165"
I just got their 1.25" set sent and it cost $80 + postage which was $16 to Perth ($US too). The instructions are pretty clear but a little in depth but as far as I can tell it will be worth it though. I used just the autocollimator the other night and it seemed to give my scope a better picture. I have to find some time to do the rest. By the way I'm using a SW dob as well. Randy Cunningham at AS was very good with service and replied to my Emails the night it was sent.
Cheers Simmo
