Basler ace USB 3.0 Camera with Sony IMX174 Sensor Excels in Solar Imaging
As an amateur solar imager, Dr. Stuart Green aims to get the very best performance out of his solar telescopes. This means having everything along the optical chain as perfect as it can be, from the lens, through special solar filters to the camera. Dr. Green approached Basler’s UK distributor Multipix Imaging regarding his work in Hydrogen Alpha Solar Astronomy, seeking a camera with the characteristics required to match his application. He chose the Basler acA1920-155um with the IMX174 CMOS sensor because the camera has a pixel size that is within the ideal range, meaning excellent image quality and resolution for features at the scales of interest within the solar chromosphere. The camera provides fast frame rates and rapid shutter speeds which means that much of the atmospheric turbulence is frozen-in on each frame. The dynamic range and sensitivity are excellent, allowing surface details and faint prominences to be captured within the same shot, so double exposure composites to display these features are not always necessary.
