A couple of days ago the sun was shining nicely (that’s the big yellow thing that hangs in the sky occasionally) so I though I would try some more solar observing. I was just slewing my scope tound when it suddenly occurred to me that my guide camera was about to get fried as there was no cap on the guide scope.
I looked around my junk box for an old binocular cap but of course none of them fitted.
Rather than going into full-blown Blue Peter mode I thought I’d look on eBay for a cap, and I came up with this. It’s like a DSLR lens cap but slightly smaller (52mm)
It works a treat and was only £1.79 from a UK source. It clips in very firmly and even has a string attached so you cant lose it
