Omegon Camera veTEC 571 C Color: Cooled APS-C camera with 26 megapixels<\/strong><\/h2>\n\n\n\n

The veTEC 571 C is the big brother of the 533 C. The same pixel size of 3.8 micrometers, but on an APS-C sensor of 23.5 by 15.7 mm. The field of view is almost three times larger at the same imaging scale.<\/p>\n\n\n\n

For those photographing large nebulae complexes with a refractor or astrograph, that is the logical step: more field of view without sacrificing detail.<\/p>\n\n\n\n

Sensor and field of view<\/h4>\n\n\n\n

The Sony IMX571 has 6252 x 4176 pixels on a diagonal of 28.3 mm and reads out at 16 bits. This provides a fine tonal gradation in both the core of a nebula and its faint outer edges.<\/p>\n\n\n\n

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 and a quantum efficiency of around 80 percent. Amp glow is absent.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Cooling and dark current<\/h4>\n\n\n\n

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.<\/p>\n\n\n\n

Because you set the sensor temperature to a fixed value, dark frames remain usable over multiple nights. This saves calibration work each session.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Connect and back focus<\/h4>\n\n\n\n

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. Use 2-inch filters to prevent vignetting.<\/p>\n\n\n\n

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.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Rear USB hub<\/h4>\n\n\n\n

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.<\/p>\n\n\n\n

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.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Software and method<\/h4>\n\n\n\n

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.<\/p>\n\n\n\n

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.<\/p>\n<\/div>\n<\/div>\n\n\n\n
