As noted...don't check your optics with a torch/flashlight...
Many people have strong opinions on washing/cleaning mirrors...who is right? Don't know and don't really care...
While you should not ever be "afraid" of cleaning, collimating, fidlding with your scope I am of the school of thought that if it ain't broke don't fix it...
A gridiron football quote often wrongly attributed to legendary Ohio St. coach Woody Hayes (actual quote is from General Robert Neyland of the University of Tennesse) I think applies here..."When you throw the ball (refering to a pass in gridiron) 3 things can happen...and 2 of them are bad"...for those of you not "into" gridiron football a pass can be caught by the proper receiver, dropped by the proper receiver or intercepted by the opposing team...hence 2 of 3 are bad)
I tend to think that some people over clean mirrors...yes, I am basically a lazy and slothful person and I am sure that the mirror will just get dirty again anyway so I don't bother...in the mean while, while I have it out cleaning there are many opportunities for me to "mess it up"...scratch, drop, spot etc.
Yes, I am sure there will come a time when cleaning is in order and at that time I will proudly/gladly wash it...but I suspect that it will be a while...
Cheers...
