Selecting Your Initial Telescope: A Guide

In the realm of astronomy, three main types of telescopes stand out: refractors, reflectors, and Cassegrain telescopes. Each has its unique features and benefits, making them suitable for different stargazing experiences.

The first type, the refractor, was the first telescope ever invented. It utilizes glass lenses at the end of a tube to bring a magnified view of the sky to focus. A popular refractor model is the Celestron StarSense Explorer LT 70AZ, boasting a 70mm diameter front objective lens, fully coated optics, and a focal length of 700mm. Refractors tend to be lightweight, easy to set up, intuitive to use, and require practically no maintenance.

Interchangeable eyepieces offer varying magnifications and increase the range of viewable objects in refractors. For instance, the Sky-Watcher Evostar 150ED DS-Pro refractor, suitable for astrophotography, sports a 150mm diameter front objective lens.

Moving on to reflectors, these telescopes have much larger apertures than possible with refractors, and amateur reflectors are available up to a whopping 500mm diameter. The Orion Optics VX8 reflector telescope is easy to transport and offers high-quality views of celestial objects. Reflectors mount the telescope tube onto a rotating base that sits on the floor and can be turned freely around, while the telescope can pivot up and down and be pointed anywhere in the sky, as seen in the Bresser Messier 8-inch Dobsonian.

Cassegrain telescopes, such as the Sky-Watcher SkyMax 180 Pro with a 180mm diameter front objective lens and a focal length of 2,700mm, are comparatively heavy and provide a comparatively more magnified view for a given size of eyepiece. This makes them ideal for viewing the planets and our Moon. However, Cassegrain telescopes may need a little tweaking from time to time to make sure the mirrors are lined up properly.

When it comes to choosing the right telescope, research is key. Consider where and how you will use your telescope, such as at home or at dark-sky sites. Specialist astronomy dealers can help answer questions about the telescopes they offer and ensure you make the best purchase for your needs.

Recommended beginner telescopes include the ZWO Smart Telescope AP 50/250 Seestar S50, the BRESSER Arcturus 60/700 AZ, and the Skywatcher Skyliner 200P Classic Dobson. These telescopes offer a good price-performance ratio, stability, portability, and suitability for deep sky and planetary observation with potential for upgrades.

Lastly, it's important to remember that a telescope is just a tool to help you explore the universe. The real magic lies in the journey of discovery that awaits you once you turn your telescope towards the night sky. Happy stargazing!

The Omegon ProDob N 203/1200 is a compact Dobsonian telescope with a 32mm super wide angle eyepiece, mirror-cooling fan, and a red dot finder. Maksutov-Cassegrain or Schmidt-Cassegrain telescopes are ideal for viewing the planets and our Moon, providing a comparatively more magnified view for a given size of eyepiece. The Sky-Watcher Explorer-130PS is a lightweight and compact reflector telescope with a parabolic primary mirror.
