Don't worry DP. There's mess. On the inside. You just can't see it!
That bloody paste should come with some kind of warning. My kitchen table, hands and t-shirt all look pretty ordinary, I can tell ya.
I've also shot the photo from the scope's pretty side
And it won't count for nought if it doesn't work. I'm not sure the sensor's stayed attached during the process of putting the scope back together?
So, neatness won't count for much then, will it ol' pal!!!!
