I'm starting to practice for the eclipse. I'm using a tripod with a gimbal head, 100-400 II lens at 400, 1.4x III extender, and a solar filter. I have a right-angle adapter for the viewfinder. I'd like to take photos every 15 minutes or so, and turn the camera away from the sun when I'm not shooting. But when I want to aim at the sun again, I'm having trouble finding it. Any suggestions?
