[g__day (Matthew)]

Guys a big request to everyone who guides well, poorly or anywhere in between - I am trying to see what to do well and what works best.

I have switched from a piggybacked Megrez 80mm to a side saddle 127mm MAK and I ponder this wasn't wise (maybe because refractors give sharper stars or maybe because the MAK needs colimination)!

I am seeing stars jump a bit (using PHD's log tracking function), so I wanted to see what other folk experience with their gear - espeically if it produces logs like PHD

Many thanks - Matt
