Yep. Am aware of all that and I've had the Lymax Cat Cooler for many weeks.
I've been struggling with this scope for about seven months, so my misgivings are not "too quick" in formation
I'm having it optically checked tomorrow. Will let you know whether your advice is on the money or whether I've had reason to doubt.
You never know Graham, it might have been rash to dismiss my apprehensions?
