So quite a long time ago i took photos of Jupiter with an ordinary camera which is not made for taking photos of the universe.I held the camera above the eyepiece and thats how I took the photos.I used a Maxvision 68 degree 16mm eyepiece. So i got a magnification of 79x.My question is that are these good photos is my scope as good as it should be? I used a Meade Lightbridge 10"

I was just asking for gods sake.A mirror like mine costs 560 euros and I definetly wouldnt want to damage it.It looks as if 560 euros is nothing to you.I have taken my instrument outside a number of times to stargaze of course-nothing happened.I am gentle with it yes,because I want it to last me for the rest of my life.Im not too gentle though,I handle it like a pieace of glass not a diamond.Its funny cause in the manual (which is made by people that are quallyfyed to do this) tells me what to do,I follow this manual and I take care of the scope how it says in the manual-gently.So by what your -
So what is a field like a magnetic or gravitational one its invisible i know that,but u can see its effects.Since everything is made out of particles could even a magnetic/gravitational field be made out of some form of particles.Even electricity is a form of particle (electrons) so why cant an electric field be a particle.Or is it just energy which is invisible made out of nothing,but its there... and we dont understand it fully.

It is a hair i used a fan to blow it off it didnt work so I got a paper towel and just slightly tryed to move it and it did,but i didnt get it off.Could I cause any damage to the mirror by using a fan for like 15 seconds on the coldest setting possible and by touching it with a paper towel?
