Omegon Camera veTEC 571 M Mono: monochrome APS-C camera for narrowband and LRGB

The veTEC 571 M combines the APS-C format with a monochrome sensor. For anyone who works seriously in channels, this is the camera that most setups end up with: a large field of view, 16-bit readout, and no color matrix that takes away light.

Using narrowband filters, you can photograph objects from an urban environment that would otherwise disappear into light pollution with a color camera.

Sensor and field of view

The monochrome Sony IMX571 measures 23.5 by 15.7 mm with a diagonal of 28.3 mm and has 6252 x 4176 pixels of 3.8 micrometers. The readout is 16-bit.

The full well capacity is 50,000 electrons at high gain and 100,000 electrons at low gain, with a read noise of around 1.5 electrons. The sensor exhibits no amp glow.

Cooling and dark current

A cooled sensor is the difference between a usable and an unusable five-minute exposure. This camera cools to 30 degrees Celsius below ambient temperature. As a result, the dark current drops to a level where faint nebulae 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. 2-inch filters are necessary with this sensor size to prevent vignetting.

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

Featured accessories

A filter wheel for 2-inch filters belongs with this camera. An off-axis guider keeps the guide star in the same optical axis as the imaging channel.
