For the first time, a telescope can cause or interrupt the stargazing experience when observing stars throughout life. If you have chosen a low-quality device or have higher expectations for what to see, you may be disappointed and never try again. That is why it’s crucial to know what you can expect from the telescope and to understand what you can see with it.
Typically, the 70 mm telescope is an excellent starting point for beginners and advanced astronomers. With it, you can get a good image and make all objects visible in the night sky from the ground. Also, it offers a clear view when focusing on the moon and the craters. You can use it to view the largest planets found in a solar system. Nevertheless, do not expect to see all the details of the planets.

Here is what you can see with a 70mm telescope:
The telescope does not give accurate information about the distance and visual quality of some objects. This is because of aperture and other crucial variables such as focal length, mirror or lens,magnification, and even weather conditions. With the 70 mm telescope, you can easily see all the planets in the solar system. You can also see the moon and make a distinction between many identifiable craters and features.You can see planet Mars and also distinguish the poles, some of the larger areas of the viewing conditions, and how close this planet is to the Earth.
The planets outside the asteroid zone are often seen in one color, and you may unlikely capture their shadows. For instance, you can view Jupiter, which looks like the light yellow dot and Neptune, which look like the sky-blue dot. Also, you can identify the rings of the Saturn under particular conditions where they have a similar color like other planets.Pluto is the smallest planets in a solar system that can be reached out using this 70mm telescope.
Some calculations can be done similar to the stars to decide the maximum limit the telescope can reach. The magnitude is used to measure the brightness of the stars. When the magnitude is higher, the object will be dimmer. The magnitude limit for a 70mm telescope is 11.9. In comparison, the stars that are very bright in the sky,which can be seen using the naked eye, are like Polaris, Antares, and Vega, have less than three magnitudes. Proxima Centauri, which is the small star that has a magnitude of 11, can be the example of the star which can use the 70mm telescope though this cannot be done using the naked eye.
You can see some great mixes of the colors in the nebulas, especially the prominent ones such as Orion’s Nebula. Generally, they look much better with long exposures.
Photos are taken using the 70mm telescopes
When taking the photos using these telescopes, you will consider sights,which will depend mainly on the light pollution, atmosphere, the state of the sky, and the quality of the eyepiece, among others. You also need a high-quality telescope that will identify the heavenly bodies in a night sky. If you’re looking for the 70mm telescopes that will not break the bank but will offer a high-quality image, keep in mind that some of the photos that may be taken using the long exposures. This means they may appear a bit colorful than what you may see in real life.Likewise, not all photos taken with 70mm telescopes using 68-75 lenses may look similar.
Generally, in a clear sky with a minimal light population, the following celestial objects in the sky can be seen with a 70mm telescope:
- Moon with the craters
- The Mercury phases
- Cloud belt on Jupiter
- The polar caps on the Mars
- The dark surface on Mars
- Moons and the shadowson Jupiter
- The rings of Saturn and 4 to 5 Moons of Saturn
- Sunspots clearly with the aperture filter
- Neptune and Uranus though not clear
- Nebulas and stars
- Some of the double stars, for example, Mizar, Albireo, etc
- Distant galaxies
- Emissions nebulas
- Stars measuring between 11.5 and 12 stellar magnitudes
- Globular clusters
- Planetary nebulas
With the 70 mm telescopes, children and young people who are interested in astronomy can use them. The range of scope does not break the bank, essentially to these cheaper telescopes. This does not necessarily mean that they are bad, but they are made for a particular audience who want to start viewing the stars.Normally, this telescope is recommended only to children under 15 years or those who want the telescope, but they are under a tight budget.
The exception to this rule is when you are looking precisely for a camping or travel telescope. The 70mm telescope is generally easy to carry, making it the best option if you want to carry a telescope with you when going on a trip.
Advantages
- It is portable
- Easy to carry
- Come with affordable price
- Have many options
Disadvantages
- Small lenses result in low image resolution
- Have few options of magnifications
- It has a smaller aperture that does not accept high magnification eyepieces. Typically, it does not matter whether you are trying to use a 300x magnification. It is not similar to 100x magnification of why the telescopes collect only limited light. The maximum magnification in every inch is 50x, which means that with a 70 mm aperture, only a magnification of 135x can be achieved.
Conclusion
If you are looking for the best 70mm telescope, you will probably benefit from the refractor because the aperture is between 50 and 150mm. The aperture of the telescopes is traditionally 114 to 400 mm. The catadioptric options are considered hybrid as they generally combine the characteristics of refractors and reflectors, but ensure excellent optical performance.
If the aperture of the telescope is lower, there is a likelihood of less cost when buying it.The 70mm refractor telescope essentially is considered the best option for beginners. Still, it may not satisfy users who have learned the basics of using this device or who,at one time, are used to see celestial objects.
