This is my widefield setup for astrophotography. The optics of the setup consists of a Askar FRA 500. This refractor has a diameter of 90 mm and a native focal lenght of 500 mm. I own a the 0.7x reducer aswell. This piece of equipment reduces the Focalratio to F/3.9 and 351 mm focallenght. The telescope is mounted on a Skywatcher HEQ5 pro. For guiding the mount I use PHD2, a William Optics Uniguide 50mm guidescope and a ZWO ASI 220 MM mini camera.
