The Bresser MikrOkular Full HD eyepiece camera is an excellent value, low cost USB imager, featuring a CMOS sensor with a resolution of 1920 x 1080px (Full HD, indivdual pixel size is 3x3 µm ).
One of the main characteristics of the new back-illuminated SONY IMX290 CMOS sensor in the Bresser Full HD Deep-Sky Camera & Guider 1.25", is the high sensitivity to light which makes it possible to also capture deep-sky objects without active cooling.
