Making flats can be quite cumbersome, especially if you stride towards automation and simplification of the process. Our flap panel makes making flat frames with your reflector/refractor telescopes part of automated routine, without hacks like LCD screens, sky with T-shirt etc.
Its an ideal tool for observatories, where you can wall mount it and turn the OTA towards it when making flat frames. If you want to do flats in the field, you can simply take it with you and put on to the opening of the OTA when you finish imaging.
Disclaimer: you can use FP1 software normally with FT1 panels.
