Direction Number of pixels Pixel width (μm) Total width (mm)
Horizontal 755 8.5 6.42
Vertical 242 19.75 4.78

 

Mode Amplifier gain

Sensitivity

(electrons/ADU)

Maximum storage electrons Typical storage electrons Readout, ADC range
252 x 242 Internal binning 17.7 ± 10% 34.4 106000 80000 1000 - 4095
252 x 242 External binning 5.9 ± 10% 137.7 320000 240000 750 - 3071

Improvements

The following improvements are planned:

  1. Apply the 245 Plus modifications.
  2. Add a filter wheel with motor control.
  3. Add temperature control.
  4. Add a low vacuum system in order to reach lower CCD temperatures. Additional cooling of up to 15 °C has been rapported using a simple handpump vacuum sistem.
  5. Replace the water cooling with air cooling.
