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 (BaronVonBarrett): Finally managed to move the screws on the front. Some WD40 and patience did the trick!
Mark Barrett (BaronVonBarrett): 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 Sanders: 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
Laura Bales: Anyone have any suggestions as to where I might find a video or easy instructions as to how to clean the NexStar 130 SLT?
Sam Akers: Most excellent! Very helpful. I was a bit hesitant to by a Newtonian because of collimation but after I watched your video I realized how simple the process is. So I went ahead and got the SLT 130 and am hoping for some clear skys here in Germany soon. Danke!
Joseph Garcia: Awesome video dude, thank you!
Carol Pearce: Thanks so much for the tutorial. Great stuff.
Familien Kring: As I understand it, it is a good quality kit. You will get great views with the different eyepieces and filters. But I myself would probably only choose another 2 eyepieces, where an 2" is among and a few filters for the 1,25". I bought a 4 mm eyepiece and I almost never use it, as eye relief is a problem. Magnification is not always for the better, the light gathering capability of the scope is also reduced, If you do not have a barlow, you need that as well (its a must have).
Amir Magharius: Hey again!
One more question.
With the Celestron Eyepiece and Filter Kit 1.25 in and this telescope, will I be able to see the same quality of planets as what you showed me in your video? Thanks!
Amir Magharius: Thanks!
SuperEdep: Hey mate they are called allen keys or hex keys in english :)
Familien Kring: And I think you wrote about collimation eyepieces. I have never tried to collimate without the laser collimater, so you have to ask elsewhere about that :-) try having a look at the astronomyforum, they are all very nice to answer when you post a question.
Familien Kring: To my knowledge they are plössl. In my opinion they are the best ones I have :-)
Amir Magharius: And are the eyepieces that come with the scope Plössl eyepieces or do they just have 1 lens in them? (sorry for all the questions!)
Familien Kring: Hi Amir. I use a Celestron 2x Barlow. Looking at the moon you need a moon filter - I use also a Celestron moonfilter. Both products are very good. I own different eyepieces. But you get far with the 9 and 25 mm you get with the scope - combined with the 2x barlow - you actually have 4.5 and 12.5 mm as well. If I should suggest you buying an eyepiece it would be a 2" one rather that 1.25". You get a great field of view (FoV), and thats brilliant when looking at Deep Space Objects!
