Obscured view through 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.

Before you do anything else, take the scope outside on a good night, find a semi- bright star (Polaris will do). Let the scope cool down! (about 45 minutes) use your highest power eyepiece and put the star in focus.
Now take the star out of focus (inner focus or outer focus) you should see a dark circle in the center with symmetrical rings around it (airy rings). If the dark circle is in the center and the airy rings are symmetrical, your telescope is collimated
Check both inner and outer focus, they should be close to the same. If not you should re-collimate.
Best done with fainter stars but for now stick to the brighter ones.
Because I own 3 scopes, I use a Hotech laser collimator. its quick and easy. Worth it if you travel with your scopes to dark sites

A good guide on how to collimate

When viewing venus or other stars there a black spot in the center of the object. It appears to be the 2nd mirror refleting to the main miror. what have I done incorrect?


You are NOT in focus. Turn the focus knob a little until you see a perfect "disk" for the planet. Stars are always POINTS of light, with a telescope or without a telescope.

Stars are ALWAYS pinpoints of light when the scope is focused no matter how much magnification is applied.

You are NOT focused properly -- when you are you cannot see the secondary mirror or the "spider" bracket that holds the mirror.

You will NEVER see a star as a disk, only as a pinpoint light. If you are seeing what looks like a donut with a dark center you are not focused.

Like others, I have trouble seeing stars. There is an obstruction, an image of the secondary mirror which obscures most of the star. Is this the spider? Others have asked the same question, but I haven't...


Yes, you are not focusing the telescope properly. When in focus you cannot see the spider.

Put the eyepiece with the largest number written on it into the telescope. Go outside during the day and practice focusing on a distant object.

You bought what we call a toy "department store telescope". Put the eyepiece with the largest number written on it into the scope. DO NOT use any 2x barlow which might have been included.

Go outside during the daytime and practice focusing on a distant object. AND---- no you will not get 450 magnification from that telescope, even though it was written in bold letters on the box.

Can't Focus


The focus screw can come out if run too far. Point it straight up, give the side of the optical tube some light 'thumps' and turn the focuser clockwise. You should be able to see the mirror moving backwards in the cell.

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.

We have focused the telescope on an object - but it appears that the mirror is in the center of the view


If your telescope is like the one in the picture it is a refractor telescope. It does not have mirrors-- the diagonal in the rear of the telescope has a mirror. Put the lowest magnification eyepiece in the telescope-- the one with the LARGEST number-- and try again. This may be easier to learn in the day time on a distant object.

Fuzzy bright stars with my Celestron CPC 1100 XLT


The image shows that the optics are not centered properly. The secondary may be tilted slightly to the 2 o'clock position. When not centered, a focused star will have an astigmatic shape, and not come to a full focus. Also check the mirror and corrector plate for dewing, that will also affect the views.

Viewing planets and stars


The problem is you are way out of focus. Turn the focus knob alot, until the star image gets much much smaller. Keep going until it looks like a pin point or a star!. The spider vane and center black dot will disappear. This black dot is actually the secondary diagonal mirror reflection in the primary mirror. The peace signs are the secondary supports. Use the lowest power eye pieces. I would not use the Barlow lens that comes with this scope as it very poor quality. Also, using this high power with this small an aperature (tube diamter) & unstable mount will be very difficult indeed. Invest in some wide angle, long eye relief low power lens. Use these for a while before going to higher powers.
