/// Lens setup
This is my very widefield setup for astrophotography. The optics consists of a Samyang 135mm lens. I use this Lens at F/2.0, the focal lenght is 135 mm. The Lens is mounted on a Skywatcher HEQ-5 Pro (belt modified). The Camera i use is a 585MC from ZWO, ocassionally i use this camera for lunar and planetary work as well. I added a Astronomik L-3 Filter to combat the chromatic aberration.
