Aperture size is the diameter of the main lens or mirror in a telescope, and it is the most important factor in determining how much light the telescope can gather. More light means brighter and more detailed images. Generally, larger apertures are better, but they also tend to be more expensive and bulkier.

Magnification is important for making objects appear larger, but it does not create more detail. Aperture is more important for determining the overall quality of the image, including its brightness, resolution, and contrast. However, magnification can still be useful for getting a closer look at specific features of an object that you can already see with lower magnification.

All telescopes are affected by light pollution to some extent, but Dobsonians and reflectors are generally less affected than refractors. This is because refractors have more internal surfaces where light can bounce around and cause glare. If you live in an area with a lot of light pollution, you may want to consider a Dobsonian or reflector, or find a dark observing location.

The essential accessories for your telescope will depend on your specific needs and interests. However, some common recommendations include:
Extra eyepieces: This will allow you to change the magnification of your telescope to suit different observing conditions and objects.
A finder scope: This is a small, low-power telescope that helps you aim the main telescope at the correct area of the sky.
A collimation kit: This is used to adjust the alignment of the mirrors in a reflector telescope.
A star chart or planisphere: This will help you identify objects in the night sky.

Dobsonian telescopes are generally the easiest to set up, as they typically only require placing them on the ground and aligning the finder scope. Refractors and reflectors may require more assembly and alignment, but the process is not overly complicated. Many telescopes come with instructions and online resources can also be helpful.

You may need a few basic tools, such as a screwdriver or Allen wrench, to assemble some telescopes. However, you do not need any special knowledge to get started. There are many resources available to help you learn how to use your telescope, such as online tutorials, books, and astronomy clubs.

Here is a general guide to what you can expect to see under typical observing conditions with different telescope apertures:

50mm-70mm: You can see the phases of Venus, the moons of Jupiter, and some brighter deep sky objects like the Andromeda Galaxy and the Orion Nebula.
70mm-100mm: You can see more detail in the planets, including the rings of Saturn and the cloud bands on Jupiter. You can also see more faint deep sky objects.
100mm+: You can start to see more challenging deep sky objects, such as galaxies, nebulae, and star clusters. You can also see more detail in fainter objects like comets and asteroids.

We are often advised that you are able to see them through any small telescope, or even binoculars. But you really need a telescope with at least 40 times magnification to clearly see the detail of the rings as separate from the planet. And the bigger the telescope, the better.

For Galactic Observations: A reflecting telescope with a larger aperture (150mm-250mm) and a moderate focal length (750mm-1250mm) is ideal for capturing distant galaxies. Telescopes such as the Orion XT8 or the Celestron Advanced VX 8" offer excellent light-gathering capabilities and versatility.

Optical telescopes, for example, can see objects up to billions of light-years away, while radio telescopes can detect signals from even further distances. However, when it comes to observing the universe's earliest moments, telescopes can only see so far.

In general, a top-quality 4-inch refractor shows deep-sky objects about as well as a 5-inch reflector or catadioptric, and might even do a bit better on the planets. Most telescopes with apertures of 80 mm or less are refractors.

Refractor Telescopes: Refractors use lenses to gather and focus light, offering crisp and clear images. They are excellent for planetary observation due to their ability to provide high contrast and detailed views.

Some of the most newly detected objects may be over 13 billion light years away, as derived from a standard model of the Universe. However, a powerful new generation of telescopes, like the James Webb Space Telescope, will be needed to confirm the suspected distances of these objects.

The most important aspect of any telescope is its aperture, the diameter of its main optical component, which can be either a lens or a mirror. A scope's aperture determines both its light-gathering ability (how bright the image appears) and its resolving power (how sharp the image appears).

The telescope you want has two essentials: high-quality optics and a steady, smoothly working mount. And all other things being equal, big scopes show more and are easier to use than small ones, as we'll see below. But don't overlook portability and convenience — the best scope for you is the one you'll actually use.

With just a small or medium-sized telescope, skygazers can easily observe planets. You'll be surprised how much of our solar system you can see! And you don't need a dark sky to view all of our solar system's planets; even under city lights, Venus, Mars, Jupiter and Saturn can be easy to see with a telescope.

In summary: Refractors generally have the edge over reflectors for a quality image, both from the standpoint of lens/mirror quality and precision optical mountings, and lack of central obscurations.

Well Made -good value for beginners

Packaged well and a quality telescope. It was suprising to get something this well made in this price range. You could tell english wasn't the choice of language in the manual. But it could be followed - a little confusing because some assembly instructions were out of sequence. But it's easy enough to figure out if you're technically minded at all. I originally purchased one that was slightly less, and the poor quality showed as the focus adjustment teeth came with sections missing. This one is really well made; but you still have to treat it gentle because the internals on this type is thrown out easily if you turn the wrong screw and it takes special equipment to properly realign. I got it together and was able to view the moon craters easily. I was just checking quickly because it is to cold to set up properly now. I need to study a little on properly setting it up and knowing which way to look. It is very well made but it's also heavy to cart around. Even considering the weight it might be well worth the hassle of moving it to a better viewing area once you become familiar with the correct way of aiming it and stabilizing the mount. People seem to forget that at the distance you're looking that the slightest bump will put the object out of you view. It kind of worries me I might be gettng into an expensive pastime; but it's a good starter telescope. It did take a little bit to figure out the phone attachment, it isn't really explained that I could find - but it isn't difficult and I'm sure there are videos.

Good starting telescope

I haven't had time to go out into the country with this yet in order to test the "Auto Align" but the motorized motion works well in manual mode. The tripod support system leaves a bit to be desired because it is too prone to vibrations. I took video of the moon on my first outing. Mounting an iPhone Xmax to take pictures is a bit tricky as the holder will press the buttons if you tighten it without first inserting some kind of spacers to prevent it.

Excellent telescope. Easy to assemble and use. Great for beginners.

Great for beginners and more. It only took 15 minutes to assemble and so easy to use. Took photo of moon just placing phone on the eye piece, since do not have camera or smartphone adapter yet. The result speaks for itself looking at the photo in this review. The tripod height is great and it is very sturdy. Great telescope. 👍

Pretty easy to use.

Easy setup. You need a clear night in order to point to three stars so you can use the automatic tracking.

A mid-grade amature telescope that doesn't compromise on quality

I totally love this telescope. It has a lot of features. I got it for the 2017 Eclipse and it really outdid itself. It has several ways of tracking solar and celestial objects. It has a bit of a learning curve, but that just makes it much more educational. It comes with a semi-adequate manual. However you will learn the most by participating in conversations on the forums. NOTE: I got a very specialized filter in order to use it to look at the Sun. It does NOT come with this. Don't melt your eyeballs! Google Cloudy Skies Astronomy for a useful website for owners of
