Last evening I took part in a public outreach event with my Q7, although I didn’t bother to take the dew shield extension.
Towards the end of the evening I suspected my ‘scope wasn’t performing as well as it was earlier and a quick flash of my torch revealed that the corrector plate was swimming with dew.
Question: do any of the fine members of this forum have experience of dew heaters on Q ‘scopes? Is there you particularly recommend?
I power my Q drive using a ‘jump-starter’ with two cigarette lighter sockets and a USB, so would have one 12v cigarette socket or 5v USB available to power a heater.
