Yeah, not bad huh? I probably should do a deeper version now that I've started

The guiding was essentially perfect for the whole 1.5hrs too with guide errors < 0.1pix in both axis the entire time

Wow. That NJP of yours is a gem. I did a 330 point T-Point model and tweaked polar alignment on my PME last night. I activated Protrack to help with guiding. I did notice an improvement in star roundness. essentially perfect round (the odd minor elongation on small stars) in 15 minute subs at 3 metres. Not bad. You can see the difference in the image when guiding is that good. Extra sharpness and detail.
