The primary advantage of lightweight truss tube Newtonian telescopes is that they are very lightweight and portable. Although they are not as compact as refractors, they can still be easily transported and set up. Additionally, they are relatively inexpensive compared to other types of telescopes, making them a good option for those who are just getting started in astronomy.
The main disadvantage of lightweight truss tube Newtonian telescopes is that they lack the rigidity of sturdier instruments. This can lead to image shift, where the image appears to move slightly as the telescope is moved. This can be minimized with careful setup and gradual adjustments, but it can still be an issue for some users. Additionally, since the telescope is lightweight and more susceptible to vibrations, the images can be blurred if the telescope is not properly stabilized.
Setting up a lightweight truss tube Newtonian telescope is a relatively straightforward process. Here are the basic steps:
- Mount the telescope onto a sturdy tripod.
- Attach the focuser to the telescope tube.
- Install the diagonal mirror and eyepiece.
- Make sure the telescope is properly balanced and stabilized.
- Adjust the focuser for sharp focus.
- Make any necessary collimation adjustments.
- Enjoy your views of the night sky!
Once your lightweight truss tube Newtonian telescope is set up properly, it is important to maintain it in order to get the best performance. This includes regularly cleaning the optics with a soft cloth and lens cleaner, checking for dust and dirt buildup on the mirrors and lenses, and ensuring that all screws and bolts are properly secured. Additionally, it is important to make sure that the telescope is well-balanced and properly collimated.
Lightweight truss tube Newtonian telescopes offer an excellent balance of portability, affordability, and image quality. They may not be as rigid as some sturdier instruments, but with proper setup and maintenance, they can provide great views of the night sky. If you are looking for an affordable, lightweight telescope, then a lightweight truss tube Newtonian is definitely worth considering.
Setting up an Explore Scientific 16 Newtonian Reflector Truss Tube Dobsonian Telescope
A short video of the procedure to set up an Explore Scientific 16" Newtonian Telescope. The video also displays some modifications I've done to the telescope. The first was to index the truss tubes, numbered 1 through 4 always returning them to the same position they were in previously. It greatly shortens the collimation procedure. The next modification was to make a cover for the open mirror box, part of it remains as a light shroud even…
