Finding a telescope that’s fit for your preferred celestial targets as well as budget is not that easy, especially considering the dozens of models on the market, many of them coming from reputable brands. There are things you must consider, such as light gathering abilities, usability, weight, as well as other factors that will affect performance.

The importance of a wide aperture

Telescopes come with a variety of apertures both wide and narrow, and what you choose will depend on your viewing preferences. A large aperture is a must if you want bright images with lots of details in them. The best Dobsonian reflector will have an aperture of at least 10 or 12 inches.

However, if you don’t want the highest resolution possible and are looking for something more affordable or lightweight, then a model with a smaller aperture should still suffice as long as you get the right accessories such as focusers and eyepieces.

 

A bit about magnification

If magnification is important to you, then you want a long focal length to obtain close-ups of distant objects, and you also want eyepieces to give you versatility on your observations and higher magnification powers.

The good thing about eyepieces is that there are many focal lengths for sale that you can choose from and add later on to make your device more versatile and your observations more interesting. Usual magnification powers are 10x, 20x and 40x, although you can get much higher than that. Just make sure you don’t exceed the maximum usable magnification as that could dramatically lower the viewing quality.

 

Ease of use

The more complex is the model you’re looking at, the more dials, buttons, knobs, and caps you’ll need to learn to control. While this can be great in the long term, it could curb your enthusiasm at the beginning.

If you’re just starting out, you could try a telescope that has a simpler functioning mechanism so that you don’t have to turn half a dozen dials before you can begin admiring the night sky. You can learn to align the telescope to stars you already know first, improve your focusing abilities with a simple Crayford-style focuser and practice on the most popular constellations. You could also opt for a computerized module which would make things easier in the beginning, thanks to the included data on thousands of celestial bodies.

 

Budget considerations

When looking for a good Dobsonian telescope, you also need to have a budget in mind. That way you can balance all the features and properties of telescope models and choose the one which makes more sense to you. If you love traveling, then a cheaper telescope that’s also lighter might be a better choice than a high-end model that costs quite a bit and is more difficult to carry.

You can always buy accessories later on, so have that in mind before overspending. You can get away with a telescope and a couple of eyepieces in the beginning, and upgrade it after you’ve learned the basics.
