HOW bad? If they are small they will not affect anything. Contact your local astronomy club and have one of the members look at your telescope.

How do i remove dent from a car without ruining the painted surface and many more?

Depends on how deep the dent is, is it a sharp crease, has the paint cracked in or near the dent? There are kits available that can pop out a simple dent, but not a more severe dent. You can Google paintless dent removal to see the kits and where to get one.

If you point it at a STAR --- it will NOT be magnified. Stars are always just points of light no matter which scope you own.

OR do you mean it's in the finderscope but not in the main tube eyepiece?? We need more information to properly answer you.

You did put an eyepiece into the focuser-- right?

No one cells a lens cell for this small telescope. Only Meade may have the part. You can call them and see--

However I doubt that they actually stock that part as the tube is imported from overseas.

I dropped something heavy on the tube of my 130GT and dented it slightly. This has affected the optics. Is a replacement tube available, and what would it cost. Noel

The dent in the tube is not the problem, or at least not the whole problem. You will have to re-align the optical parts, which have been disturbed by the impact or possibly the change to the geometry of the tube. This is called "collimation" and you can find lots of articles about how to do it on the web. It is a complex process, though.

Just fitting a new tube will not fix the problem, as the various optical elements will still need to be collimated after having been fitted to a new tube. You would be better off to either live with the dent or remove the mirrors and knock the dent out before re-collimating the scope. You don't need a new tube, but you will have to re-collimate in any case, so save the money. Maybe you could pay for a specialist to do the collimation instead.

I have a swift astronomical telescope model no. 859 (no D). I need an owners manual and information on how to order parts. Mark J. Lanza

This is a 6 inch Dobsonian mounted reflector. They are VERY simple to assemble-- only two parts-- the base and the tube. The small finder scope goes on top. The eyepiece goes into the focuser. That's it.

No manuals exist for that brand but all of them assemble and are used in the same fashion. Here is a manual for an Orion brand Dobsonian just like your scope.

Focuser could be broken. Call a dealer and see if you can purchase a new focuser-- or a replacement focuser(which you can do).
