Hi guys.
Bit of a newb bino question.
How can you tell if your knockies are out of collimation?
I recently received some new Pentax 10x50PCFWPII binos from OPT in the US.
While I'm happy enough with them so far, I do notice that even when I focus stars in the centre of the fov there still appears to be those little telltale spikes or comet tails that won't go away.
I've only ever owned a telescope so this is all a bit new to me
Is this actually normal?
Is there a test one can do (star test??) to check collimation?
Can this particular bino be collimated or is it factory set and therefore needs to be returned if the optics have been bumped out of collimation?
Many thanks
