ASI678MC

Description

The ZWO ASI678MC is a versatile colour camera featuring Sony’s IMX678 back-illuminated Starvis II sensor. With 2.0 μm pixels on a 1/1.8″ format (3840 x 2160, true 4K), it bridges the gap between planetary and deep-sky imaging — delivering high resolution for solar system targets while offering enough sensor area for smaller nebulae and galaxies.

The IMX678’s Starvis II technology delivers outstanding low-light performance with very low read noise, making the ASI678MC suitable for EAA (electronically assisted astronomy) and short-exposure deep-sky work in addition to its planetary capabilities. The 2.0 μm pixel pitch provides excellent sampling at moderate focal lengths (1000–2000 mm), resolving fine planetary detail that larger pixels would miss.

Connectivity is via USB 3.0 for fast frame rates at full 4K resolution. The camera includes a built-in ST4 guider port and is fully compatible with ASIAIR, ASCOM, INDI, and all major capture software. Powered entirely via USB, the compact body fits a standard 1.25″ nosepiece and weighs under 100 g.

If you want one uncooled camera that can do serious planetary imaging and dabble in deep-sky work, the ASI678MC is one of the most capable options in its price range. It’s particularly well suited for imagers who want 4K video of Jupiter and Saturn but also enjoy capturing bright nebulae and star clusters.
