Omegon Camera veTEC 294 C Color: cooled 11.6 megapixel camera for deep-sky<\/strong><\/h2>\n\n\n\n

The veTEC 294 C combines the Sony IMX294 with active cooling. The sensor has a diagonal of 23.1 mm and 4.63 micrometer pixels, a combination that pairs well with fast refractors and short focal length astrographs.<\/p>\n\n\n\n

The full well capacity of 64,000 electrons is remarkably large for this sensor class. Stars saturate less quickly, which is reflected in the color of bright stars within a nebula.<\/p>\n\n\n\n

Sensor and dynamics<\/h4>\n\n\n\n

The sensor measures 19.11 by 13.0 mm and has 4128 x 2808 pixels. Readout is at 14 bits, delivering a dynamic range of 84.4 dB.<\/p>\n\n\n\n

The read noise ranges from 4.1 electrons at low gain to 0.87 electrons at high gain. The peak quantum efficiency is around 80 percent.<\/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 focal distance of 17.5 mm. The included adapter sleeve converts it into a 2-inch connection, allowing you to slide the camera into the focuser like a 2-inch eyepiece. The filter thread is 2 inches.<\/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

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