QHY20 Series

The QHY21, QHY22 and QHY23 cameras feature Sony's latest high sensitivity ExviewII CCD sensors: ICX674, ICX694 and ICX814.

These sensors have very high QE (close to 80%) and very low thermal noise. With dual stage TEC cooling technology these cameras can achieve temperatures 45C below ambient.

By comparison with the competition, the 10 to 15C of extra cooling helps ensure great results, even on hot summer nights!

The readout noise of QHY21, 22, 23 is typically 5 electrons. Readout noise is very important when capturing faint deep sky objects, especially when using narrowband filters.

Lower readout noise means you can still get good images even when stacking fewer frames.
