Yes, I’ve been using a Lodestar with the OAG in my QSI 583 wsg CCD camera. Previously, I used a separate guide scope side by side on a Skywatcher EQ6 Pro. Moving to the OAG allowed me to remove 8 Kg of counterweight, the EQ6 Pro gave a sigh of relief.I can recommend an OAG, I’ve been using it now for about 16 months. I’ve not had any problems yet finding a star to guide by.RegardsDave
