Question about Edu-Science (10166) 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?
You are seeing the "spider" holding the secondary mirror-- the scope is not in focus--
Practice focusing during the daytime on a distant object at least 100 yards away-- use the lowest power eyepiece-- which is the one with the LARGEST number on it.
