CCD cameras
Astronomical Observatory of Belgrade (AOB) provided several cameras and instruments to be able to work on all three telescopes. These instruments are stated and briefly described below:
Port 1 on @ telescope Milanković
This port is equipped with focal reducer 0.65, so focal length is 7132 mm (instead of 11200 mm). There is also field flattener f/7.6 which gives F=10.64 m.
Andor iKon-L 936 CCD
Andor’s iKon-L 936 is designed with scientific imaging in mind. The 2048 x 2048 array and 13.5 μm pixel pitch combine to deliver a 27.6 x 27.6 mm active image area, TE cooled down to -100°C. The iKon-L offers outstanding resolution, field of view, sensitivity and dynamic range performance. Ultimate sensitivity performance is achieved through combination of > 90% QE (back-illuminated sensor), low noise readout electronics and exceptionally deep TE cooling.
Technical details:
| Active pixels | 2048 x 2048 | |
| Sensor size | 27.6 x 27.6 mm | |
| Pixel size (W x H) | 13.5 μm x 13.5 μm | |
| Active area pixel well depth | 100,000 e- (150,000 e- for BEX2-DD and BR-DD models) |
|
| Maximum readout rate | 5 MHz | |
| Read noise | 2.9 e- | |
| Maximum cooling | -100°C | |
This camera is equiped with following filters: Johnson B, V, R, I, L, filters and Hα , Hα continuum and SII.
