Chubster Posted October 31, 2006 Share Posted October 31, 2006 Hi all. I know this subject has been covered loads of times but im still confused Think I have just read far too many articles and given myself headblock !I think I understand the principle so no need to cover that again but was wondering if any other Skywatcher Newt owners on here could actually point me in the right direction re the correct screws to use!!!!! I have been on the SW site and my scopes screw do not match any of the configs that they show :)Soz for being dumb but any help would be appreciated Chubster Link to comment Share on other sites More sharing options...
Ant Posted November 1, 2006 Share Posted November 1, 2006 Take a pic of the end of your tube and I'll sort you out. Depenmding on the scope that you have. It'll either be just three bsprung bolts to tighten or loosen. Or 6 allen key bolts to loosen / tighten / lock.Ant Link to comment Share on other sites More sharing options...
daz Posted November 1, 2006 Share Posted November 1, 2006 ChubThere should be three small allen bolts next to the three larger cross-head screws.Undo these allen bolts first, then collimate using the larger screws, then re-tighten the allen bolts.They should not be forced-tight, just enough to hold the cell in place. Recheck you collimation afterwards. Link to comment Share on other sites More sharing options...
ZOG Posted November 2, 2006 Share Posted November 2, 2006 And dont forget that those 3 small screws on the bottom are only holding the base cap on. You have to remove the cap to get at the collimation screws. Link to comment Share on other sites More sharing options...

Kaptain Klevtsov Posted November 3, 2006 Share Posted November 3, 2006 Sometimes it's the simple things that are annoying when missed off the instructions. When this happens, even RTFM doesn't work. Hope you have it sorted now Chubster.Captain Chaos Link to comment Share on other sites More sharing options...

FLO Posted November 4, 2006 Share Posted November 4, 2006 Missing or generic instructions are not uncommon! Here is a link to downloadable instructions for Skywatcher telescopes (PDFs): http://tinyurl.com/y7madrAlternatively, post here or ask your dealer...

Andrew* Posted November 11, 2006 Share Posted November 11, 2006 I tried giving my newt a wee collimation the other day, but I think I ended up de-collimating it! Now stars are even more triangular than they were. I followed a number of instructions, but it didn't get me very far, and it seemed perfect anyway. I made a collimation cap, so at least that's a little of the way there. What's the best resource?Andrew Link to comment Share on other sites More sharing options...

Ant Posted November 11, 2006 Share Posted November 11, 2006 Film canister with a hole in the end?of course!I had a laser mate and just couldn't get on with it! I've used the film canister ever since and get a better collimation than I ever did with the Lasermate.But other swear by them!Ant Link to comment Share on other sites More sharing options...
Andrew* Posted November 17, 2006 Share Posted November 17, 2006 Okay, I think I made a much better job of collimation today. I haven't tested it on the stars yet, but I have a question: why mark the mirror? What is the need of sticking a great blob in the centre of your optics? And how do you actually go about it? Do you have to remove it?And also, I found something very interesting while collimating my scope. When looking into the focusser, I noticed a blue-ish ring (EDIT: the ring was right in the middle, in the shadow of the secondary mirror), that separated into two rings, or two half rings, when collimation was out, and when I got the thing what I thought to be properly aligned, the ring was perfect. Has anyone noticed this?Andrew Link to comment Share on other sites More sharing options...
daz Posted November 17, 2006 Share Posted November 17, 2006 AndrewThe mirror is marked so that you know where the exact centre is. Then, when you look through your collimating eyepiece, you see the main mirror, the secondary and the centre mark, all as concentric circles. Then you know you are close to collimation. Many people finish it with a star collimation to ensure accuracy.HTH Link to comment Share on other sites More sharing options...
Andrew* Posted November 17, 2006 Share Posted November 17, 2006 okay, thanks daz. Anyway. Just took my scope out for a quick bash. It's a clear night, but I'm a little tired and not quite in the mood. Collimation is vastly improved, although not perfect. I'm just waiting for the planets to come back. I wanna see Jupiter and Mars now, but they're just sticking by their favourite hot buddy, the sun. Is there a transit of Jupiter across the sun sometime soon? Venus and mercury are interesting enough, but I would love to see with my own eyes Jupiter's size in relation to teh sun. Why don't we ever see Jupiter transit photos?? (just kidding!)Anyway, enough extracting the urine. I want to progress from M45, M31 and M42. What would you guys recommend? I think I need some more reliable literature.Andrew Link to comment Share on other sites More sharing options...

Mikesmad Posted November 27, 2006 Share Posted November 27, 2006 Have a look here. There is a movie which shows you what you see and what to do!Hi,My first post on here and I would like to thank you Daz for the link to the best training vid I have seen.I am just a beginner to this star-gazing lark and I must have been very lucky collimmejiggin my 4.5"Meade.....................cos this 8" unnamed (weel not quite, but I had better not swear on ma first post) Newtonian reflector has resisted alignment so far!Does anyone know why the secondary mirror shows up so plainly, when I am looking through an eyepiece, on this 8", yet is hardly noticeable on the 4.5" ?

Staypuft Posted July 5, 2011 Share Posted July 5, 2011 Thanks to Daz for the link to the video - this makes more sense than the several dozen or so sets of written instructions I have sweated over for the past three weeks since I caught the bug! Now that I think I have this collimation malarkey cracked (there is still some doubt - my vision has suffered greatly over the past few days and the matched crosshairs may be an optical illusion) the clouds have rolled in!
