I had thought this out carefully before fitting; got myself some nitrile surgical-type gloves and an air blower to remove dust. The ZWO filter comes in a foam-lined plastic box for protection which is good, but the filter also has a tight-fitting clear film on both sides which needs great care to remove safely (I used the scissors on my Swiss Army knife). When I fitted the filter and reassembled the camera, I could see minor marks all over the lens, presumably from the clear film. I removed the filter and cleaned with a cotton bud soaked in Eclipse optical cleaning fluid and dried with a new micro fibre optics cloth which removed the marks. Not a major issue but one to be aware of.
As always, a swift and trouble-free transaction from F.L.O.
