Omegon Camera veTEC 585 M Mono

Omegon Camera veTEC 585 M Mono: compact cooled monochrome camera

The monochrome veTEC 585 utilizes the most sensitive sensor of the compact veTEC models without a color matrix. With a quantum efficiency of approximately 90 percent and a read noise of about 0.8 electrons, this is a serious narrowband camera in a small format.

The 11.1 by 6.3 mm sensor format fits well with short refractors and for those who want to learn how to work with channels on a limited budget.

Sensor and sensitivity

The monochrome Sony IMX585 has 3840 x 2160 pixels of 2.9 micrometers. The readout is performed at 12 bits, up to 47 frames per second at full resolution.

The full well capacity is 40,000 electrons. In front of the sensor is an anti-reflective window, so you determine the transmission curve with your own filters.

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 focal distance of 17.5 mm. The adapter sleeve turns it into a 2-inch connection with a 2-inch filter thread. Please take into account the space needed for a filter wheel.

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.

Featured accessories

A filter wheel is part of the setup with a monochrome camera. An off-axis guider keeps the guide star in the same optical axis as the imaging channel.
