Hi everyone,
I'm new to the forum so hoping that I'm posting in the right place.
I have a Revelation Collimator which I have used successfully in the past with my newtonian, but the battery in the collimator has run out and I can't for the life of me work out how to replace it. I've searched all over and can't find any advice or instructions.
One end of the collimator unscrews, but only reveals the top of what I presume is the laser unit. This appears to be fixed in place. There are 3 screws on the body, presumably for collimating it. I don't want to undo these unecessarily, but cannot see any alternative.
Any advice gratefully received.
thanks in advance
MrRusty
