Peter Rusling has also used one of the Amazon supplied light panels for taking flats. He says:
“I’ve bought one of these excellent panels and thought I’d share that the light USB L4S version will mount safely on a £15 articulated TV arm in an obsy using Velcro. This allows me to position it up against either of my scopes and has the added bonus of providing an observatory light (albeit white) when stowed against the wall.”
A picture of Peter’s setup is shown below.
