I've been checking out some of the goodies I've bought while the dollar has been high and the sky is sort of clear and I've noticed what looks like a periodic error showing up in PHD. I've never seen this before until last night and I thought it may have been balance so I spent extra time tonight to ensure my balance was right. I recently greesed the mount and spent many hours adusting the worm gears. Do you think I've got it wrong? Where should I be looking to resolve this, it's destroying long exposures.
Got the allen keys ready, just waiting for this last sub to finish and I'll have a go at it. Just shooting the horse looking for reflections but it's diving into the city lights now anyway ..
