Celestron Origin Mark II Review: The Biggest Smart Telescope

The Celestron Origin is the heavyweight of smart telescopes. Where most rivals use 30–50 mm lenses, Origin uses a 152 mm (6-inch) Rowe-Ackermann Schmidt Astrograph (RASA) at f/2.2, a design that puts the camera at the front of the tube and collects light far faster than a small refractor. The Mark II, item #12100, adds Celestron's 678C camera with a Sony IMX678 sensor. It costs $4,299. We compared Celestron's published specs with hands-on reviews of the original Origin, which shares the optics, mount and app. We have not tested it ourselves; see how we research.

Key specs

Specs from Celestron's product page, checked October 17, 2026.

Image quality

f/2.2 is the key number. A RASA collects light so quickly that Origin builds images from 10-second exposures and rejects frames with tracking errors. Space.com and Live Science, testing the original Origin under Bortle 4 skies, got "crystal clear images of nebula and galaxies almost instantly", with "no noise" visible and stars as "pinpoints with no color fringes", even without a filter. The Mark II's IMX678 has smaller 2 µm pixels and higher resolution than the original IMX178 camera; Celestron says owners of the original can buy the 678C as an upgrade.

Planets and the Moon

Origin is a deep-sky instrument. Both reviews managed sharp Moon images in manual "Snapshot" mode, but neither could get Saturn to focus in auto or manual mode. Space.com's verdict: Origin "isn't going to be your go-to for viewing the moon or the planets".

Setup and the app

Celestron's StarSense camera aligns the telescope automatically, and focus is automatic. The reviewers had the original Origin connected "in seconds" and found targeting, tracking and focusing worked "without issue". Several people can watch the live view at once, which suits families and star parties. The app is minimalist, with few manual controls; the reviewers found manual focus slow to respond, with no fine adjustment, and the mount motors "fairly loud".

Weight and setup

Origin is three pieces: a 10.6 lb tube, a 17 lb mount and a 14 lb tripod, 41.6 lb in total. The reviewers found the tripod sturdy and the mount's carrying handles useful, and recommend a padded bag for the tube. It runs from its internal battery for 6-plus hours or from mains power. Celestron says it fits "in any car", but this is a backyard scope, not a travel one.

Upgrades and advanced use

Celestron keeps adding features through software: dithering arrived in April 2026 and a mosaic mode in September 2026. For longer exposures you can add an equatorial wedge; Celestron recommends its StarSense Autoguider beyond 30 seconds. Raw frames save to a USB drive for processing on a computer.

Who should buy it

• Buy it if you image from a backyard or a short drive away and want the most light-gathering of any smart telescope, with room to grow.
• Look at the Dwarflab Draco if you want guided long exposures and 90 mm of aperture in a 12 lb package for about a third of the price.
• Choose a Seestar S50 Pro if you need something portable for under $1,000.
