Celestron Origin vs Origin Mark II - Camera Upgrade, Specs & Which to Buy

Celestron Origin vs Origin Mark II - what’s actually different (and why it matters)If you're looking to buy a smart telescope for astrophotography, the Celestron Origin has already made headlines as a best in class product - and the Origin Mark II raises the bar in one very focused way. Below, we break down the specific differences between the two models and discuss the practical benefits of the Mark II upgrade for hobby stargazers and astrophotographers.Short summary: same RASA optics, better cameraThe original Celestron Origin and the Celestron Origin Mark II both share the same fast 6" Rowe-Ackermann Schmidt Astrograph (RASA) optical design (with 152 mm aperture, 335 mm focal length, f/2.2) - that’s the core strength of the setup: a fast, wide-field astrograph built into a simple, app-driven offering. The major difference in the Mark II is the camera itself: the original Celestron Origin sensor has replaced. The Origin’s original Sony IMX178 sensor has been upgraded with a newer Origin 678C camera, this is based around Sony’s Starvis 2 technology (IMX678). Camera sensor upgrade - the details matterCelestron Origin: shipped with a Sony IMX178 colour CMOS sensor (≈6.4 MP, ~2.4 μm pixels). This sensor is proven and sensitive (STARVIS back-illuminated), however some users were expecting a newer, higher-res Starvis 2 sensor when the Celestron Origin initially launched. Celestron Origin Mark II: now includes the Origin 678C camera featuring Sony Starvis 2 technology: 8.4 megapixels, ~2.0 μm pixels and a modern 16:9 aspect sensor - higher resolution and finer pixels compared with the original on-board camera. Celestron say this upgrade provides improved sensitivity, finer detail and better live-stacking results. Why this matters in practice: smaller pixels plus a higher pixel count for a given area mean you get finer sampling of the fast RASA optics (more pixels across galaxies and nebulae), and Starvis 2’s improved performance in low-light conditions helps capture fainter detail during short stacked exposures - exactly what smart telescope users rely on for speedy production of images. Other hardware and software features - largely the same (but still important)Beyond the change of camera hardware, the Origin platform still includes many great aspects that make it a compelling all-in-one astrophotography rig: dew heating system, integrated autofocusing, filter drawer for 1.25" or 2" filters, a single-fork alt-az mount with included internal battery, built-in…
