Overview

The Sky-Watcher Quattro 250P is a 254mm (10-inch) f/4 Newtonian astrograph designed primarily for astrophotography, though it handles visual observing well too. That fast focal ratio means significantly shorter exposure times compared to slower scopes, making it practical for imaging faint nebulae and galaxies without sitting at a computer all night. The oversized secondary mirror is sized to fully illuminate both APS-C and full-frame camera sensors, which is a genuine consideration many cheaper imaging scopes skip.

Knife-edge baffles help control internal reflections, a detail that matters when you are processing images and want clean results. The dual-speed Crayford focuser gives you the fine control needed for critical focus with a camera, and the included tube rings and dovetail mean you are not hunting for accessories before your first session. One honest note: this telescope ships as an optical tube only, mounted on a basic alt-azimuth base.

For serious astrophotography, you will need a solid equatorial mount, which adds cost and weight to consider. The optics at this price point are genuinely impressive, but the mount situation is the key thing to plan around before buying.

Key Features

  • 254mm aperture at f/4 captures faint deep sky objects with exposures roughly six times shorter than an f/10 scope
  • Oversized secondary mirror provides full illumination across APS-C and full-frame sensors, avoiding corner vignetting
  • Dual-speed Crayford focuser allows precise, fine adjustments needed for accurate camera focus
  • Knife-edge baffles reduce internal stray light, which improves image contrast in both photography and visual use
  • Tube rings and Vixen-style dovetail are included, making it straightforward to mount on a compatible equatorial head
  • At 15kg for the optical tube alone, an equatorial mount capable of handling this scope is a necessary and significant additional investment

Excellent Value For Money. Needs Other Gear For Optimum Use.

Recommended for medium to advanced skill level. An amazing "light bucket." 10" mirror grabs every available photon for stunning DSO astrophotography. Internal light baffles help with light pollution, but a dew extender shield is recommended to make sure the only light you get is from space. Dew heat...

Beast of a telescope!

Fast and sharp! I use mine with the Starizona Nexus 0.75 and the Apertura 0.95 coma correctors. Worth every penny! I saved some $ by purchasing mine used on Amazon. I adjusted the spider vanes in order to get really sharp diffraction spikes on my stars and it has held up with no further adjustments ...

It comes from China so shipping takes a month.

Overall score 4/5 Stars. 3/5 for Shipping. This rating is purely based on it's arrival. I love this telescope and I'm glad it arrived intact. It was delivered to me in a month's wait. Shipped from China and went directly to Celestron in NJ. Then shipped to out to Amazon distribution center in CA for...
