Maxim rules have both pro 5 and essentials 2.04 editions though have never tried guiding through it, though I think I will give it a go now lol. I think you need to check out my tut post and master stacking and alignment with it . It kills anything i've seen and has a heap of stacking options and alignment options as well as some of there own in house methods. Haven't used pixinsight though so can't make a comparison with it :/ Lol i wouldn't pay for PS and i doubt 1 in 20 people here have, if your got money to burn send it my way
