Noticed the picture today on spaceweather.com was taken with an all-sky mirror.
Does anyone else use one of these. What size mirror. Seems that a stainless steel mirror would be good if a heater was put under it. Acrylic would be cheaper. I've tried the baby moon hubcap method but couldn't find one bigger than about 10 inches and the surface quality was very poor for this application.
