Omegon Camera veTEC 585 C Color: compact cooled camera with high sensitivity
The veTEC 585 C is the most affordable way to start with cooled astrophotography. The Sony IMX585 has a quantum efficiency of about 90 percent and a read noise of about 0.8 electrons: numbers you normally find in more expensive sensors.
The sensor size remains modest, with a diagonal of 12.84 mm. This fits well with small refractors and for those who want to experience what cooling does to an image first.
Sensor and sensitivity
The sensor measures 11.1 by 6.3 mm and has 3840 x 2160 pixels of 2.9 micrometers. It reads out at 12-bit, at 47 frames per second at full resolution.
The full well capacity is 40,000 electrons. Combined with low readout noise, this results in clean images, even with shorter exposures.
Cooling and dark current
A cooled sensor is the difference between a usable and an unusable five-minute exposure. Thermoelectric cooling brings the sensor significantly below ambient temperature and keeps that value stable. The dark current thus drops to a level where faint nebula structures emerge above the noise.
Because you set the sensor temperature to a fixed value, dark frames remain usable over multiple nights. This saves calibration work each session.
Connect and back focus
The camera has a T2 thread with a flange distance of 17.5 mm. The adapter sleeve makes it a 2-inch connection, with a 2-inch filter thread.
With the loose 12.5 mm adapter, you reduce the flange distance, which provides space for a filter wheel or an off-axis guider in the optical train.
Rear USB hub
There are two additional USB ports on the back. You can connect a guiding camera or an electronic focuser to them, for example, so that only one cable runs to your computer.
The hub works with USB 2.0. For the camera itself, you use a USB 3.0 port on the computer, otherwise the read speed will drop.
Software and method
Control is via ASCOM or INDI, with which the camera cooperates with N.I.N.A., SharpCap, APT, and Siril. Omegon's free capture software can be downloaded.
Note: the veTEC cameras do not have an ST4 port and are not intended as an autoguider. For guiding, combine the camera with a separate guiding camera, for example from the GUIDE or veLOX series.
Included
- Camera with thermoelectric cooling
- Adapter sleeve from T2 to 2 inch
- USB 3.0 cable
- Power supply 12 V / 3 A
- Rugged transport case
Featured accessories
An off-axis guider or a separate guiding camera is part of every cooled setup. The 12.5mm adapter frees up space when you add a filter wheel.
For whom yes and for whom no
- ✓ The first refrigerated camera without a large investment
- ✓ Deep-sky and planetary imaging with a sensitive sensor
- ✓ Small refractors and astrographs
- Wide-field recordings requiring an APS-C sensor
- Anyone expecting an auto-guider port in the camera
