I started imaging just over 3 years ago using an Orion 50mm guide scope in the offset shoe of my newt, worked ok
Then advanced to an Orion 60mm guide scope with helical focuser piggyback mounted on a dovetail bar central axis on my newts
So much easier to achieve focus on PHD2 using the star profile tool , also has a wider field than the 50mm and there a larger selection of guide stars
(Orion 60mm guide scope with helical focuser has a focal length of 240mm)
