Description

The Explore Scientific AR152 Air-Spaced Doublet, is a classic air-spaced, crown-and-flint doublet achromatic refractor, and at 152mm (6-inches) of aperture, it provides the brightest images and highest resolution of the AR Series.

Our design goal was to provide an extreme value by providing true diffraction-limited optics at a price that will allow more people to explore the sky with a wide-field (f/6.5) large aperture refractor. Images of deep-sky objects are stunning at low powers and all at a small fraction of the price you would pay for a similar aperture apochromat refractor.

At high power, the moon, planets, and double stars are revealed in sharp, high contrast. Designed to handle the rigors of public star parties and educational outreach, the Explore Scientific AR Series telescopes come with heavy-duty, high quality components, including a 2" dual-speed focuser, a one-piece 2" diagonal with 99% dielectric coatings, Explore Scientific Hybrid Finder Scope Base installed with an 8 X 50 non-illuminated straight-through finderscope and quick release bracket, and a cradle ring assembly with Vixen-style dovetail mount. Just add a few eyepieces and the alt-azimuth or equatorial mount of your choice and you’ll be ready to discover the Universe!

Astrophotography with the AR152

With its diffraction-limited optics, proper baffling, precision dual-speed focuser, and rugged construction, the Explore Scientific AR152 is also a solid performer for the astrophotographer.

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.
