About the Sky-Watcher Flextube 200P 10" Collapsible Dobsonian Telescope

This 10" 'light bucket' gathers enough photons to make you feel like you're traveling through deep space. This is especially true when you've thrown it in your car and headed to your local dark site, which is made incredibly easy thanks to the innovative design of this Dobsonian.

Many truss tube Dobsonians solve the portability problem by being designed to disassemble, which often results in a frustrating (and time-consuming) reassembly experience. Sky-Watcher have instead created a collapsible design. Just loosen three locking screws and bring the front and back cells together. Then lock them back down for transport. Preset indentations on the truss tubes allow you to easily extend the telescope again without losing collimation.

Teflon bearings allow movement so smooth that sweeping adjustments can be made with one finger. A tension clutch keeps the OTA firmly in position with the twist of a lever.

The 10" aperture and fast focal length of this telescope make it ideal for wide-field, deep-space observation of even the faintest nebulae and galaxies. Sky-Watcher's dedication to quality design and top-notch components result in an instrument that will delight even seasoned astronomers. The parabolic primary mirror and elliptical diagonal mirror are made of borosilicate glass which are finely polished to ensure high smooth surfaces and high-contrast images. On each mirror surface, aluminum is vacuum deposited and then over-coated with hard quartz (SiO4). Additional layers of Titanium Dioxide (TiO2) and (SiO4) are then applied, resulting in 94% reflectivity and bold-bright images in the eyepiece.

Features

  • 254 mm (10 inch) Dobsonian-style Newtonian • 1200 mm focal length (f/4.7) ideal for deep-space visual observation
  • 2” single-speed Crayford-style focuser for smooth focusing • 1.25” adapter means that you can use both 2" and 1.25" eyepieces
  • Comes with everything you need to start viewing right away, including two 4-element Plössl eyepieces (25 mm and 10 mm) and an 8x50 RA erect-image finderscope
  • Solid rocker-mount with Teflon bearings and tension clutch for altitude
  • Teflon bearing for azimuth

Explore Scientific Mak Cas 152 with EXOS2GT MOUNT

I did considerable shopping around and finally decided to buy my 152 Mak from Telescope Space. Ryan was very helpful with all my questions concerning Explore Scientific and my specific purchase. After a short period using my scope and mount, the mount seemed to have more play than it should have. Ryan had the Explore Scientific owner call me directly, where he immediately offered to exchange my mount. He also had the factory ship out the new mount while I was still using my original unit. Excellent service and sales support from both Ryan at Telescope Space and Explore Scientific. I will buy again from Telescope Space!

Monocular

Very clear, I am impressed for $38

Ryan knows what he is talking about.

Prompt customer service, positive attitude, great results

An engineering beauty

I have owned many tripods. I have spent years trying to find an altazmith tripod that could carry a reasonable amount wieght, yet be portable, and have the handling and maneuverability of a Porsche, especially as the power goes up. This is a very well enginered tripod. It is as if they said let's not try to make it look a certain way, let's make it work a certain way, and that's why it looks extraterrestrial. Very well made with very little plastic. Fit and finish is close to perfect........9.9 on a 10 scale....5 stars +.....Carlos B.

Great Scope & Mount

As a higher-level amateur, I was looking for a decent scope & mount that I can modify for my needs. The 130mm Newtonian scope fits my needs quite well. It comes with a 25mm eye piece--which is great. I would consider purchasing other eye pieces at the same time to give you a variety of magnification options. I'd recommend something like a 12mm and 8, or 6mm eye pieces to complement the 25mm. Getting a 2X Barlow will double your eye piece viewing options. The higher number will give you a wider view, smaller number a tighter, more magnified view. In order to just resolve the bands & zones of Jupiter, I need to use an 8mm eyepiece. For exploring Lunar geography, or seeing the Galilean Moons, the 25mm is sufficient. Saturn is just discernable, until you switch-out the eye piece for a 12mm, or smaller. The heavy & stable tripod mount is easy to set up, and the large rotation nobs allow you to smoothly track your subject as the Earth rotates. The Red Dot spotting site is dead-on accurate (once you dial it in). If you want a good, intermediate telescope: one that's neither too cheap, nor one that's too expensive, the 130mm Newtonian should fit your needs quite well.
