At a push yes, please add a note with the submission to say set horizons at 15º and do unguided if possible
also keep exposures short and take more of them as its broadband so 60-120s exposures will be fine
I was going to test unguided on pier-1 this evening anyway's to see if we can do 60, 120 or 180s unguided
The reason I say unguided is guiding at 15-20º is a pain at 1700mm focal length
Kind regards
Steve
