Hello everyone. Been desperate to try out my Hotech flattener with the canon on the Tak,so after venturing out last night and seeing OH MY GOD! CLEAR SKY!! did the deed. The conditions didn't last long before the cloud returned,and the seeing and light poll were annoyingly bad too,so only got 30 mins worth. Anyway,the Hotech seems to do the job and clean up the edges pretty well. Roll on winter,and hopfully some long clear spells! cheers all
