Question about Celestron AstroMaster 130EQ Telescope
It appears that the focus mirror is being seen in the center of the view. We have focused a very bright star - but have a cross in the middle of it - and no it is not the Finder we are looking through, and it is not simply crosshairs. There is a specific obstruction. It is visible with both with the eyepiece and without.
Any idea what we could be seeing? And how to fix the issue? I've found the same problem as well - I'm using a Celestron Astromaster 130EQ Newtownian Reflector. I've had a look at a couple of stars and Venus and am getting very poor results- a cross in the middle of the viewfinder and very blurry and grainy image. Doesn't seem to matter what I do with the focus knob - the image just gets more or less blurry (what you'd expect) but the cross is still there.
You can slow down dew forming on the mirror by NOT pointing the telescope toward the sky during cool-down-- just leave it parallel to the ground. Same goes for your eyepieces -- leave them covered, or inside a case.
