I had the cover thrown in when I brought the 200P/HEQ5 scope second hand - really nice heavy stitched and seemed nylon material in army green. Not sure who the manufacturer is, but will check for labels when I get home and PM details. I wouldn't leave it out if going away, but we have a nice quiet area and restricted overview/no direct access to the back garden. Normally I would bring it in, but keeps the noise down early in the morning and a bonus if the following night looks clear.

Green Witch do an excellent scope cover...

Thanks Grunthos - that looks like the exact thing and the dimensions and description (vent covers.brass rings) sound spot ont - I'll check and confirm tonight
