Hi guys I'm new to astrophotography and have just purchased a EQ6-R-Pro. My current OTA is a skywatcher 150pds. I've been doing visual astronomy since I was 7 years old (im now in my mid 40's)and have been using EQ mounts as long as I can remember, however, I am well aware of the limitations of polar alignment using the polar scope for imaging. I am going to invest in a guide scope and camara ( skywatcher 50ed and ZWO 120MM) and run it through NINA/PHD2. my question is, is it worth buying the qhy polemaster or is the polar alignment plug in though NINA sufficient to get accurate polar alignment? Many thanks Olly
