I have been asked by a few forum members to detail how I built my imaging rig based around the Samyang 135mm f2 lens and ASI1600MM CMOS camera. A number of people asked within the topics /images I posted last year of M31, Andromeda and Orions Belt / Sword and the topic recently reappeared thanks @StarManFlorida   For the specific imaging configuration that I used for these images and the components used are ZWO ASI1600MC ZWO Mini 5 position EFW fitted with Baader 1.25
