The Good
The Bad



There are many factors to give some thought to if you’re in the market for a 90mm telescope, and that’s why we’re here to help you make the best decision. Aside from the size of the aperture, you also have to take into account many other details, and we’ll make sure to tackle them all in our comprehensive buyer’s guide. Check it out below.

What will you be able to see?

If you’ve ended up here, you’re probably looking for the best 90mm refractor telescope or a catadioptric or reflector alternative that raises up to par. But, if you’re a beginner, what you first have to consider is the celestial objects you can take a look at with the help of such a device.

Most telescopes that measure between 60 and 80mm in aperture will offer you decent images of Saturn, Jupiter, the moon, as well as several bright star clusters and cloudy nebulas. Anything above 90mm will let you take a peek at the same celestial objects, but the neat thing will be that you will be able to see a greater amount of detail, as well as dim objects such as galaxies.

With every aperture increase, you’ll be able to see greater detail and notice a difference in terms of performance. Unfortunately, telescopes that have apertures of 150mm are not as budget-friendly as the formerly mentioned alternatives.


Portability matters

Unless you plan to use your telescope in a closed space for the rest of its existence, you’re probably interested in taking it on the road and doing a bit of stargazing outdoors. In that case, you need to analyze purchasing factors such as the weight of the product and its overall size.

If it comes with its own carrying case, even better, as you’ll be able to transport all the components without worrying about getting them damaged. While paying attention to the dimensions and the weight of the product is useful, without a doubt, you might have to take the time to go through the best 90mm telescope reviews as other users just like you can let you know just how easy or hard it is for them to put the telescope together and then take it apart again.

What type of telescope do you plan to get?

Another factor that should be on your mind is the exact kind of telescope you might be looking for. There are three types to choose from, and each and every one offers both advantages and disadvantages.

Refractor units are somewhat common compared to their counterparts. They are usually thought of as good-quality alternatives that have a rugged build and that boast a construction that enables them to be portable. Unfortunately, due to their rather long tube, you’ll have to use a sturdier and larger tripod.

Reflectors have smaller tubes when compared to those of their refractor counterparts. They’re also good choices if you’re focused on portability, and perhaps even more so compared to refractors. The only drawback about them is that they require a bit of time spent on cleaning and maintenance as they tend to accumulate dust around their lenses.

Catadioptric units are combinations in that they offer the pros of both refractors and reflectors. Because they are remarkably powerful and compact, these options tend to cost a pretty penny so they might be less recommended for beginners whose budgets are quite limited.

The 90mm aperture and 910mm focal length that this unit comes with will allow you to have a peek at deep-sky objects, the Moon, Jupiter, Saturn, as well as planets, in general. The classic refractor design seems to be a clear advantage, as is the fact that the Starry Night software is part of the deal with this model.

Based on the information that we have come across, it appears that the mounting system that accompanies this product could be less stable than you’d like it, which is why it might be a good idea to purchase a separate tripod.

The two included 1.25-inch Sirius Plossl eyepieces allow you to select the level of magnification you need to perform your astronomical observations based on the weather conditions or your purpose.

The 1.25-inch rack-and-pinion focuser enables smooth adjustments to the perfect observation height and setting for optimal viewing results every time.

In fact, we couldn’t help noticing that most online marketplaces sell this model for less than two hundred dollars, which means that it is a rather budget-friendly alternative.
