An 8 minute exposure through a 200mm lens. Unguided EQ-6 mount. With this mount and my polar-alignment skills it seems that a 60s exposure is the maximum achievable at 200mm.
I have a QHY5 guide-camera and a 500/5.6 Rubinar which I plan to use for auto-guiding which will (I hope!) put an end to the squiggly stars.
