reavertor: Thanks for the excellent tutorial - I followed your steps exactly with my NexStar 130 and it's working great!
oystersource: Brilliant! Thank you!
Anthony Weaver: Thank you for the nice tutorial.
jorgelawes: It's called a hex key but we refer to it as an allen wrench more often.
Leslie Boom: Amazing tutorial. Just got this telescope for christmas. :-)
Erzfreund Der Dritte: Dankeschön (:
Simon Henshaw: Simply brilliant!!! Many thanks for this super easy collimation tutorial, my kids and I can now look forward to a great Autumn and Winter's star gazing (through our newly collimated NexStar 130SLT :-) )
Freddy Acosta: Nice, I got this scope today. Will need to get me a Collimator tool asap.
David E: Thank you for sharing your knowledge. Happy star gazing, your friend from the other side of the pond.
Hemi Blue: Thanks for a helpful video. I'm having a problem with my primary adjusting screws. 130 SLT... Using a 2 mm hex. I cannot move my adjusting screws in either direction. They are so tight it's a bit scary trying to move glengarry them . Any advice would be more than appreciated.
kpmac1: Thanks so much for this video. I've had a 130 SLT for about 8 years and have NEVER collimated it because, although I had bought a regular collimation tool years ago, after reading and watching videos, I could never figure out how to do it correctly. I watched this video, got a laser collimator for $28 and was able to collimate my scope in about 3 minutes. Can't wait to see the improvement!
Andy Hull: Thanks for this! I just followed along and collimated my own SLT 130 that I've had for a three weeks. It was slightly out of collimation so now I'm itching to see if I notice any difference!
coope1999: Was really worried about doing this but after watching your video it looks really easy. Thanks!
Silvano de Gennaro: I have an SLT 114 and I used exactly the same cheshire laser as you, but I get a blurred large dot on the primary lens, like if the laser had gone out of focus. Of course the laser is OK when projected directly on the wall, so it must be the secondary lens that puts it out of focus, but I don't know why. When adjusting the primary, the red dot is reflected back to the target very large (as big as the whole target) and very blurred. Any idea why?
Mark Barrett: Finally managed to move the screws on the front. Some WD40 and patience did the trick!
Mark Barrett: Any further advice on adjusting the front mirror screws. Can't turn mine and aware that I may be putting too much pressure on the mounting arms which are flexing.
Chase Em Down: This was extremely useful. Thank you very much.
Eric S: What size allen wrench did you use to collimate the secondary mirror? None of the allen wrenches I have used will catch on anything when I put them in the hole.
Sanjay Colaco: Thanks for that mate, very helpful. I have one that haven't used for a few years so a great video to start with collimating it first and enjoying the Aussies skies. Whats eyepieces and barlow do you use?
flowernoire: very helpful. thank you
