funny grant last night i was out and indeed it is the second night i have found that my images at zenith seem to trail, like m16 last night but objects lower down i can rattle off 10 exposures at 2 mins unguided and have round stars...but at the zenith they seem to trail or are fuzzy
it could possibly be a little moisture i realised last night because the OTA is straight up and it may settle a little more readily.... perhaps
pat
