About this deal

Things close to the North Star trace smaller arc than things further away, so the amount of blurring you get depends on where the object is in the sky. The 8SE can display detail in even the faintest celestial objects thanks to the light-gathering abilities of its 8 inch aperture. This is still too much magnification to photograph the Andromeda galaxy, however (which is 6 full moons wide). So, I think my biggest misconception about astrophotography was that all of those amazing internet photos were taken with giant telescopes. Generally, the higher the Strehl ratio, the lower the Astigmatism and Coma meaning a better image quality from your instrument.

Use the included NexStar+ hand control to locate over 40,000 celestial objects, or take a Sky Tour and let your telescope show you the best objects currently visible. We also provide an edition of the exciting astronomy magazine, “Sterne und Weltraum” with each telescope. While we think the Celestron NexStar 8SE is a great telescope, it’s also the case that, like all things in life, it is not perfect (sadly).This telescope collects light at an f-ratio of F10, which is much “slower” than a typical reflector or refractor telescope.

However, Highpoint Scientific offer an 8SE bundle with all of that stuff, plus all the eyepieces and filters you need to get started. This photo is yet another plug for owning a focal reducer - the clarity of the stars is greatly improved compared to my non-focal reducer photos.This adds another 11 lbs (5 kg) to the setup but is only just powerful enough to support the 12 lbs OTA. The Nexstar 8SE will perfectly track Saturn across the sky, keeping it centered in frame, but, like the arrow, Saturn’s rings will start pointing up at 45 degrees, flatten, and then point down over time. Heck, even if you’ve had a 6-inch refractor already, this one will blow your socks off as it gathers 77% more light.
