I need a large flatpanel for flats. My Takahashi µ250CRS has an electronic focuser, meaning I need to take my flats immediately prior to takedown. If I disconnect the electronic focuser remote, or remove its batteries, I believe the focuser will reset its position. Yes I could takedown and leave the focuser remote and its battery in place and do flats later when I wake up, but it's just a waste of batteries, or worse, prone to error if I accidentally touch the remote during takedown.
I saw this on Gumtree and am wondering if this would be a good candidate for taking flats :-

It seems there is some control of brightness adjustment and seems it'll run off USB power.
Anyone tried this? It seems much cheaper than dedicated astro flatfield panels.
