More Issues with FLATs

Описание к видео More Issues with FLATs

I've moved my imaging train to the Explore Scientific ED102 and am using the ZWO ASI1600MM as the imaging camera with this scope. I performed a Dew Experiment by accident: Do we need dew straps for refractors with long dew shields? YES! So, I've been having to take and re-take a lot of flats ... and ran into another problem. My off-axis guider shadow is not calibrating out and I have those pesky circular reflections. I've solved the circular reflection artifact problem by changing a setting in the ZWO Filter Wheel driver, but the OAG shadow is still there.
