A3 EL panel mounted between 2 sheets of MDF. OZStockman supplied the MDF - one sheet is complete, the other has a hole to sit around the front aperture of the scope and holds the panel in place. It was actually the offcut from around a Bahtinov mask that he cut for me. I just asked him to cut it from an appropriately sized piece of MDF to fit over the A3 EL panel. I had already bought the EL panel so needed something to mount it in. In retrospect, I should have just bought a Gerd Neumann panel from the start. My overall cost was probably about half vs a GN panel, but a lot more fiddling to get into a usable state. The A3 panel is just large enough for a 10 or 11 inch scope.
Seems to work OK. I tell CCD Commander to acquire automatic flats, but not to move the mount or wait until dawn - it works out the exposures. Usually collect 10-20 flats per filter.
