Omegon Camera veTEC 432 C Color: cooled camera with 9 micrometer pixels
The veTEC 432 C is a specialist. The Sony IMX432 has 9-micrometer pixels, more than twice as wide as those on most deep-sky cameras. As a result, each pixel captures a lot of light, making the camera suitable for telescopes with a long focal length.
There's a global shutter, which is unusual in cooled cameras. Combined with 94 frames per second, this is also a serious option for solar work.
Sensor in pixel size
The sensor measures 14.1 by 9.9 mm with a diagonal of 17.6 mm and has 1600 x 1100 pixels. The readout is at 12 bits.
Large pixels mean a coarse image scale at short focal lengths. Behind a Schmidt-Cassegrain or a long Newtonian, the camera is precisely suited, for example, for small planetary nebulae and compact galaxies.
Cooling and dark current
A cooled sensor is the difference between a usable and an unusable five-minute exposure. This camera cools to 40 degrees Celsius below ambient temperature. The dark current thereby drops to a level where faint nebulosity emerges 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. With the adapter sleeve, you can slide the camera into the focuser like a 2-inch eyepiece. The filter thread is 2 inches.
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.
Please note: veTEC cameras do not have an ST4 port and are not intended for use as autoguiders. For guiding, combine the camera with a separate guiding camera, for example from the GUIDE or veLOX series.

Featured accessories
An off-axis guider is virtually indispensable at long focal lengths. The 12.5 mm adapter frees up space in the backfocus.
For whom yes and for whom no
- ✓ Deep-sky photography at long focal length
- ✓ Small, bright objects with a lot of signal
- ✓ Solar work where speed and cooling are important
- Wide-field shots, the resolution was kept deliberately low
