Questions & Answers

Who helped the people with the barrels that were loose?

There is something I don't quite understand about this question. There is no point in having a loose eyepiece barrel, but if the old diagonal isn't locking the eyepiece tightly it would do the trick. It seems that some eyepiece barrels fit differently within the standard diagonal than others. There is a nice twist to this one. You should be able to solve that issue. I've always been able to keep everything I need securely in place with it.

Do you know if this works on N a Maks?

The diagonal and eyepiece should work if you're using a regular angle and eyepiece.

Having an eyepiece holder tube that is loose and shaky is not acceptable. I need to tighten it. How do I do ?

You might want to try turning the red ring if you're talking about that. The eyepiece should be better secured when you turn it clockwise. When it is turned counterclockwise, it will become tighter. You should tighten the set screws on the visual back like you did with your previous diagonal if you are speaking of the whole I'm assuming the diameter of the eyepieces matches that of what's on the There are 25 to 1 in this comparison. 2. 25 is a good number. There is a 0 to 2 scale. A zero).

The first piece I've ever made for a constellation and my first dielectric mirror. The lens is a 90mm focal length refracting telephoto. In this case, does the view provide a correct, rectilinear L/R reverse, or an ?

If I set the scope to flip, I believe the image would flip- It has nothing to do with the fact that it is Orion and dielectric. An object flipped by a diagonal mirror will appear upside down. A mirror reflects light, so that's its nature. The two things I was most concerned about were Fold as shown The diagonal does an outstanding job of carrying light to my eyepieces and securely holding my expensive eyepieces without being too expensive over the course of a year. I have far more expensive diagonals, including one that uses quartz. The Orion I use most often is this one.

It's a great diagonal, but the unit I received was loose
3/5

It's a no-brainer It's a great diagonal, but the unit I received was loose. Having used this diagonal a number of times, I'm quite familiar with it. This is a product I know well and appreciate quite a bit. I received the same unit as before, but it is very different from the previous units. There is a loose area in the tube between the eyepiece insert and the tube. As of right now, I am only able to give two stars. It's because I know this I piece is good and I do not want to give it one star. As soon as I get a chance, I will contact Orion to see if they can handle this issue.

This means they are fit and healthy
5/5

Through the diagonal, I was able to find Item was exactly as described, it arrived on time, and it was in good condition. As a user of the diagonal, I have found its functionality to be greater than any other I have used. With the Twist-Tight design, you're way ahead of any thumb-drive My lenses are held in by a screw. The price of some of them is pretty high. And also. At that dark site, there are no thumb screws to lose!.

The fit and brightness of this pair are exceptional
5/5

It is a good thing that Twist Tight collar secures My Celestron NexStar 127 came with a Celestron diagonal eyepiece. I replaced it with the Orion twist tight star diagonal, and the fit is perfect. I didn't notice anything loose about it. Despite making firm contact with my eyepieces without leaving any marks, it grips them securely. My new one has a much better visibility than the one I replaced. You can operate the twist tight with your bare hands or gloved hands at the same time, and it is easy to use. Construction is all metal with an anodized aluminum collar that is twist tight. This is a great product and it works great. It fits very tightly and it has great looks as well. There is no slop in the fittings and the twist tight keeps the eyepieces very secure.

I had a shaky and loose grip as well
3/5

Another reviewer and I have had the same problem with the tube receiving the eyepiece turning and shaking. The red ring around the eyepiece holds it in place, so tightening it has no effect. However, tightening the tube as a whole causes it to rotate and shake, so the eyepiece I had inside would not work. Despite the fact that the image was clear and beautiful, the fact that it needs to be fixed in place with welding or another method to ensure that the eyepiece receptor does not move makes it a poor.

In Orion 1, you are given one star
4/5

The twist is 25 inches. I found the user manual to be somewhat clearer than the one that came with the StarPro 102. My only issue was the loose section the eye piece sits in so I had to remove the Phillips screws from the bottom and front and tighten them. Set the glass with 5mm set screws, being careful not to damage the glass.

Do yourself a favor and grab There's no easy way to change eyepieces without one of these!

It is much easier to change eyepieces with this
5/5

I think this is an excellent addition for ease of Screws of all sizes are no longer an issue. If the weather is cold, the eyepiece can be held securely and changed while wearing gloves. Telescopes come with a diagonal image that provides better quality than the one that comes with telescopes.
