About the Sky-Watcher Flextube 300P 12" Collapsible Dobsonian Telescope

With the turn of a few screws, you'll be able to pop this Dobsonian in your car for transport to your local dark viewing spot, where you'll best take advantage of its enormous light gathering aperture.

Most large truss tube Dobsonians tackle the portability problem through disassembly. This can often lead to frustrating and time-consuming reassembly experiences. Sky-Watcher instead makes use of an innovative collapsible design. Simply loosen three locking screws and collapse the assembly until the front cell and rear cell meet. Tighten the screws for easy transport.

The altazimuth system is the epitome of user-friendliness. Sweeping adjustments can be made with one finger due to teflon bearings for the altitude and needle bearings for the azimuth. A twist of the tension clutch keeps the OTA firmly in place when viewing.

The 12" aperture and fast focal length of this instrument deliver even the faintest deep-space objects to the eyepiece, and brighter objects will render in brilliant detail. 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

  • 305 mm (12 inch) Dobsonian-style Newtonian • 1500 mm focal length (f/4.9) 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
  • Aluminum plate with needle bearings for azimuth

  • Two 1.25 " eyepieces (25mm and 10mm)

Great Telescope for beginner

Astronomer myself, I choiced this telescope for my 5 years old son who wants to explore the Universe.... And I ve been very impressed by the global quality of this product... all the optics are good enough to watch planets and near Messier objects....It s a great deal for all beginner (young and even expert)...

Great Telescope Company

I thought my ED80 Triplet was nice but this ED102 FCD100 is awesome. Delivery and customer service was excellent.

Nice Apo and a Real Value

I bought this scope for an industrial client whose needs are industrial, not astronomical, and this Explore Scientific ED127 is intended to be a beam expander in various Interferometric testing setups. For this, optical quality must be high and the carbon fiber tube is a plus for thermal stability. My purchase of the Explore Scientific ED127 F7.5 APO Triplet through Telescope Space was straightforward and pleasant. Ryan made sure everything was smooth.
Upon receipt I tested the scope by looking at a power pole 700 feet away, one that I have used for many such tests. The star test from the insulator glints was good – the focus snap was crisp, the in-focus diffraction blur was round with a faint first ring. I did not look at the through focus balance with a narrow passband filter as it was obvious there was no SA3. Color correction is very good as you would expect with the glasses used. There is no color in focus, and only a hint of subtle color fringing in the just out of focus edges of details. Extended details on the pole were rendered as well as, or better than, with any similar scope I have used on this target – this includes TMB, Astrophysics, and Takahashi scopes.
The build quality of the carbon parts is gorgeous. The metal parts are good quality anodized machined. I would prefer machined tube rings as the cast ones supplied are a little chintzy compared to the rest of the scope. The rack and pinion focuser works well, but the feel is not as good as some stock friction focusers I’ve used. Considering the extra high weight capacity of the focuser the feel may be the price paid. Overall I think the mechanical appearance and function is in line with the price.
I would certainly consider the Explore Scientific ED APO FCD100 triplet scopes for my personal use. My transaction with Telescope Space was great and I will do business with them again.

Review on Firstlight AR 102mm f9.8 on EXOS NANO EQ3

A great package for the price! The mount is steady! The Optics excel, in that the resolution and contrast are everything to be expected in a quality refractor! H.B. Appleton, Hi.

The staff at Telescope Space were very supportive and helpful as well!
