Excellent value beginner telescope for Astronomical Observing, Easy to use!
The Dobsonian Telescope is the preferred type to see Deep Space Objects, as well as a great planetary instrument. This is without a doubt one of the best value telescopes you can buy. The 135mm aperture allows you gather immense amount of light, and the solid base allow you to easily adjust it to target your preferred view. You simply spin it left or right, and adjust the altitude up or down.
The way you use this telescope after you have set it up, is to look through the ‘red dot finder’ which is attached to the telescope. It paints a ‘red dot’ into the black sky showing you where it is pointed. You rotate the telescope and adjust it up and down until what you want to look at is lit up. Now switch your view to the eyepiece to see your target up close! Switching out the eyepieces changes the magnification of your instrument.
Even though we have called it a beginner telescope, it is only so in the sense that it is easy to operate and learn. It completely avoids the confusing ‘EQ’ Equatorial controls that leave new telescope users frustrated and leave the telescope in the corner after a few attempts. This is a telescope that is so easy to operate that you will find yourself looking out at the sky regularly wondering if tonight’s another good night to use it.
The f/8.1 design ratio makes it significantly easier to focus on objects perfectly and allows the telescope to be used with a great variety of eyepieces later on. It also prevents a common visual abberation with telescopes called “coma”.
If purchasing for a young child, be aware young children have short attention spans. Don’t be disappointed if early viewings are brief (“O I can see it!” then triumphantly turn away) no matter how spectacular the view. It takes time for children to learn and many repeated exposures to Astronomy for the habit to get started. We recommend the following obvious objects for children (Moon, Saturn, Jupiter, Teach them to find and identify the Southern Cross, then show the “jewel box” and teach them to look for the coal sack. Go from there. You will need to persist with it over some time before it ‘catches on’.
This design is not suitable for terrestrial (earth) viewing.
This scope comes with unusually good eyepieces. The 25mm features an oversized lens which makes it particularly easy to look through without “blackouts”. This is particularly friendly for new users where the eyepieces will work without requiring a particularly good eye placement. The metal version of this eyepiece was reviewed by William Paolini and got excellent reviews. The 7mm eyepiece is actually the 7mm “Planet killer” eyepiece that we sell by itself for $49.95. Both eyepieces come with a good quality twist case.
- Dobsonian Design – Very good optical quality.
- 135mm mirror with a 1100mm focal length, f/8.1
- 2″/1.25″ Metal Crayford Focuser

What should I expect?
The Kson 135mm dobsonian is tremendous fun and is a serious telescope that will allow detailed observations of an assortment of Astronomical objects. The 25mm eyepiece allows wonderful “wide field” views, and allows you to take in the enormity of space, which the 7mm allows great close up views. The 25mm when coupled with the barlow in practice allows views between the two eyepieces and very close up views when coupled with the 7mm “planet killer” eyepiece.
