Omegon Camera veTEC 571 M Mono cooled, Sensor D=28.3 mm

Omegon Camera veTEC 571 C Color cooled, Sensor D=28.3 mm

The Omegon Pro veTEC 571 C features the new Sony IMX571 sensor. With a pixel size of 3.8 µm this camera in APS-C format is the big brother of the veTEC 533 C

high quantum efficiency (~80%)

low readout noise (~ 1.5e-)

high full-well capacity (50,000 e-)

ADC: 16-bit

Zero-Amp-Glow: No amplifier glow

Professional deep-sky astrophotography: The giant sensor is perfect for wide nebulas, star fields or the lunar surface. Compared to other astrophotography cameras, this one is more akin to the generously sized sensors in DSLR-cameras.

Thermoelectric cooling: The cooling system reduces noise in the image. At 40°C below ambient temperature, the noise caused by dark current is almost completely gone. In addition, the precise control of the sensor´s temperature is very helpful for calibrating your astrophotos with dark frames: They all can be made at the correct temperature. The final images are impressively clean.

Additional connectors - USB hub: 2 USB ports at the back of the camera are reducing the cable chaos of your astrophotography setup. Additional devices (for example guiding cameras) can be daisy chained through this hub. A separate cable connection to your pc for every single device is now a thing of the past.

Working distance - adaptation to the telescope

The camera can be adapted to almost any astrophotography setup, thanks to a T2 thread and a short back focus of only 17.5 mm. Of course a 2" nosepiece adapter allows you to simply connect the camera like any 2" eyepiece.

Rugged transport case

The provided sturdy case with fitting foam inlet gives anyone peace of mind when transporting or storing this valuable camera.

Professional planetary, lunar and solar astrophotography: Capturing the shadows of Jupiter´s moons, divisions in Saturn´s rings, detailed mountain ranges on the Moon or impressive prominences on the surface of the sun - these impressive targets in our solar system can only be photographed properly with a very high framerate: This freezes the so called seeing, turbulences of the atmosphere that usually hide details from view. This ´lucky imaging´ technique is now a breeze, thanks to sophisticated electronics and the high bandwidth of the camera´s USB3.0. We recommend the Region-Of-Interest feature of the supplied Omegon AstroPhotoCapture software: This optimized the framerate by reading out only the relevant part of the sensor that contains the planet or detail you are interested in.

Built-in IR cut filter: A filter window protects the sensor chamber from dust and humidity. The Omegon Pro colour cameras are equipped with and infrared-blocking filter. Modern CMOS sensors are sensitive to infrared light, so a correct color representation in the final image is only possible by removing these wavelengths before capture. On the other hand, the Omegon Pro mono cameras feature an anti-reflection window, that is transparent to a wide range of wavelengths from the ultraviolet to the infrared. You can add your own filters for unrestricted control over your transmission curve - invaluable for advanced imaging and photometric applications.

Convenient capture software: The included software Omegon AstroPhotoCapture allows straightforward and easy-to-learn camera control. The correct camera settings during the capture process are crucial for astrophotography. AstroPhotoCapture gives you full control over every parameter of your camera, without an overburdening interface. Easy to follow tutorials cover the capture process step for step, to make your first astrophotography session successful. The software is compatible with Windows 7, 8 and 10.

Compatibility: The Omegon Pro cameras are compatible with a wide range of available astrophotography programs through the common interfaces ASCOM and INDI. Native compatibility is also being added to a growing number of programs, like PHD2 and N.I.N.A.

Question:
What is the optimal gain and offset for the VeTEC 571 camera??

Answer from Teleskop-Service:
The situation is a bit different than with the ZWO ASI2600 camera. With ZWO, the camera automatically switches between low conversion gain (LCG) and high conversion gain (HCG) at a certain gain value. This automatic switching can be seen through a clear jump in the readout noise: Link to the original image by ZWO

A gain of just over 100 can be recommended here as a rule of thumb, so that you can put the camera in HCG mode.

With the veTEC571 (and other ToupTek-manufactured cameras) this jump does not happen automatically. You can manually switch between LCG and HCG. If you only operate the camera in HCG mode, for example, then there is no sudden jump in the readout noise, but a gradual decrease. A concrete recommendable point is therefore not to be mentioned. Also, unity gain cannot be recommended - unity gain is just not in the adjustable range for either the ASI2600 or the veTEC571.

Which gain should be chosen depends entirely on what and how exactly the customer wants to photograph. If he needs some value without prior knowledge, then we recommend:

HCG, low-noise mode, gain: 250 (on the gain scale between 100 and 100,000), offset just any middle value so that values ​​at the bottom of the histogram are not clipped.
