Hi , I’m using a Mach 1 mount , my gear at present is just a qhy183 M with a Samyang 135 mm lens , I’m presently shooting sh2 308 . I’m wel polar aligned with no DEC drift . I’m noticing a tiny trail only in RA only after it crosses the meridian . However I balance east heavy only with the cw bar horizontal . Should I offset it a little more than the existing east heavy position ? Thanks Suresh
