The first thing you need to consider when buying a telescope is what you want to observe. Are you interested in viewing planets, galaxies, or deep-sky objects like nebulae and star clusters? Different telescopes are better suited for different types of observations. Refractor telescopes, for example, are best for viewing planets and the moon, while reflector telescopes are better for deep sky viewing.

Next, you'll want to consider the aperture size of the telescope. The aperture is the diameter of the primary lens or mirror, and it determines how much light the telescope can gather. Generally, the larger the aperture, the more light the telescope can collect, resulting in brighter and clearer images. A good rule of thumb is to choose a telescope with an aperture of at least 70mm for beginners.

Another important factor to consider is the telescope's focal length. The focal length determines the magnification power of the telescope, with longer focal lengths providing higher magnification. However, higher magnification isn't always better, as it can also result in a narrower field of view and dimmer images. For beginners, a telescope with a moderate focal length is typically a good choice.

When it comes to the mount, there are two main types to choose from: alt-azimuth and equatorial. Alt-azimuth mounts are much easier to use and intuitive for beginners, while equatorial mounts are better for tracking objects as they move across the sky. Consider how much time and effort you're willing to put into setting up and aligning your telescope when deciding on a mount type.
Don't forget to consider additional accessories that can enhance your stargazing experience. Eyepieces, filters, and a star chart can all be useful tools for beginners. Also, be sure to factor in the cost of any necessary accessories when budgeting for your telescope.

Buying your first telescope is a fun and exciting journey that can open up a whole new world of exploration. By considering factors such as aperture size, focal length, mount type, and additional accessories, you can make an informed decision and find a telescope that meets your needs. So, start your stargazing adventure today and prepare to be amazed by the wonders of the universe.

Types of Telescopes:
Telescopes have long been used for observing distant objects in the sky, from planets and stars to galaxies and beyond. But with so many different types of telescopes available, it can be overwhelming to know which one is the best for your needs. In this blog post, will provide a detailed of the various types of telescopes and their unique features.
Refracting Telescopes:
Refracting telescopes, also known as dioptric telescopes, use lenses to collect and focus light. They are the oldest type of telescope and are typically long and narrow in shape. Refracting telescopes are best for observing bright objects like the moon, planets, and double stars. They are also easy to use and require minimal maintenance. However, refracting telescopes can suffer from chromatic aberration, which causes colors to separate and produce blurry images.

Reflecting Telescopes:
Reflecting telescopes, also known as catoptric telescopes, use mirrors to collect and focus light. They were invented in the 17th century by Isaac Newton and are known for their large apertures and high image quality. Reflecting telescopes are ideal for observing faint objects like galaxies and nebulae. They are also free from chromatic aberration, making them a popular choice among astronomers. However, reflecting telescopes can be bulky and expensive due to the large size of the mirrors.

Compound Telescopes:
Compound telescopes, also known as catadioptric telescopes, combine lenses and mirrors to achieve the best of both worlds. They are compact and versatile, making them a popular choice for amateur astronomers. Compound telescopes come in two main designs: Schmidt-Cassegrain and Maksutov-Cassegrain. Schmidt-Cassegrain telescopes are known for their high image quality and wide field of view, while Maksutov-Cassegrain telescopes are compact and portable.
Radio Telescopes:
Radio telescopes are designed to detect radio waves emitted by celestial objects. They are typically large and dish-shaped, with receivers that capture radio signals and convert them into images. Radio telescopes are used to study distant galaxies, pulsars, and other radio-emitting sources. They are essential for understanding the universe beyond the visible spectrum of light.
Infrared Telescopes:
Infrared telescopes are designed to detect infrared radiation emitted by celestial objects. They are used to study cooler objects like brown dwarfs, dust clouds, and protostars. Infrared telescopes are typically equipped with special detectors that are sensitive to infrared light. They provide valuable insights into the formation and evolution of stars and galaxies.
Each type of telescope has its own strengths and weaknesses, so it's important to consider your specific needs and interests when choosing a telescope. Whether you're a beginner stargazer or a seasoned astronomer, there is a telescope out there for you. So grab your telescope and start exploring the wonders of the universe!

Hi Jon if your wanting take some photos , then you should be looking at the pds range which are more suited for astrophotography. As for the aperture it's not that important in photography work as most people go for a lighter scope so a 130pds or 150pds is a good choice, if your wanting it for visual then the 150/200 is a better choice either way bigger scope = bigger mount = more money, good luck which way you go,John.
Hi. Get the 130 and learn the ropes. You then get the 200 and so have the best of both the wide field and single object fields of view. You can't have just one telescope anyway; it's an unwritten rule at SGL! Just make sure that the mount is capable of carrying whatever you get in future. The new belt driven EQ6r looks like a good bet.
Sorry, not very well expressed, but hoping you get the drift. Cheers and good luck.
Another top spot for viewing the eclipse will be the city of Dallas, Texas. Situated slightly east of the center line, Dallas will still experience a substantial duration of totality, with over 3 minutes of complete darkness. The city's skyline and urban environment may provide a unique backdrop for the eclipse, creating a memorable setting for those looking to witness the event in a bustling city atmosphere.
For those looking to escape the hustle and bustle of city life, the rural areas of Oklahoma will offer a peaceful and serene setting for viewing the eclipse. Towns like Shawnee and Ada will be right in the path of totality, offering unobstructed views of the celestial phenomenon. With wide open spaces and expansive horizons, these locations will provide a picturesque backdrop for watching the eclipse unfold.
