Hi Gaz,
that sounds like an interesting night out.... always great to interact with the evenings nature/ fauna....
Although the idea of your camera bouncing off the ground isn't so great!!
Very nice image with very good colour!!
I think that's 'Murphy's' law you're thinking of ?? some thing like................
"If there's a probability of it gonna happen, it will"!!
I had this trouble with my 2" compression ring and the MPCC, so decided to go back and use the standard single screw setup on my Moonlite focuser... works very well. The correct sit very square and firm.
Another thing you can if you don't have a standard single lock screw option... and I've been told by a few folks who've done it, is to drill and tap another screw opposite or 120 degs around from the existing one in your compression ring, this will give you even compression on both sides and evidently works with the MPCC....
Your a lucky guy to have a Tawny frog mouth visit.... you must have some animal magnetism... either that or it wanted a bite from your late night snack
Cheers for now
Rich
