Overview
The ToupTek SkyEye26AM Plus is a cooled mono astronomy camera, the monochrome version of the 26AC Plus: Sony’s APS-C IMX571 with 26 megapixels of 3.76 µm pixels, a 16-bit output and no amp glow. Peak quantum efficiency is above 91%, and the mono sensor records every pixel at full resolution through each filter.
It’s built for narrowband and LRGB imaging through a filter wheel, and the wheel can plug straight into the camera’s USB hub. The sensor needs 36 mm unmounted or 2″ filters; 1.25″ filters will vignette.
Refractors and astrographs from roughly 300 to 1000 mm suit it well: at 500 mm it samples at about 1.55″ per pixel. Two-stage cooling takes the sensor up to 43 °C below the air temperature and holds it at the set point you choose.
USB hub: one cable back to the computer
The back of the camera has a four-port USB 2.0 hub. The filter wheel, guide camera and focuser plug into it, so only one USB 3.0 cable runs back to the computer. A 512 MB buffer holds each frame while it transfers, so a slow USB link or a busy laptop doesn’t drop frames.
The camera runs from 12 V. USB doesn’t power it, and ToupTek recommends a 5 A supply when the hub is in use.
Dew, tilt and back focus
The sensor sits in a sealed, dry chamber, and the front window has a heater with four power settings. Three sets of push–pull screws in the body correct sensor tilt without a separate tilt plate.
Back focus is 17.5 mm from the M54 thread. The supplied 21 mm and 16.5 mm extenders bring it to the standard 55 mm used by most flatteners and reducers. Take the front adapter off and it drops to 12.5 mm, which helps when an off-axis guider and filter wheel have to fit in the same space.
