You should be able to get what are called "Filter Wrenches" online or through a local camera store. One grasps the filter the other grasps the lens extension where the filter threads on.

I bought a 800 to 1200 lens it seems to have a hazy look when I take pictures I have tryed different distances and I use a tri-pod and wired remote any tips

There are several possible reasons for this.
You may be seeing haze. With such a long lens, you're often taking pictures of things very far away. In such cases you're going to get haze (smog, smoke, fog, and other stuff in the air). A UV filter can reduce the effect somewhat. To see if this is the cause, try taking some pictures of something closer (like the opposite end of your living room) and compare.
If the sun or other bright light source is shining onto the front of the lens, that will reduce contrast and produce a hazy look. Use your hand or a piece of black cardboard or something similar to shade the lens (being careful not to get the object into the picture). Take pictures away from the sun and toward it (not directly toward it, just in its general direction) and compare.
The lens may be dirty. Clean the front and back with lens tissue or a microfiber cloth. Don't take the lens apart to clean its innards unless you have a lens collimator and other gear needed to put it back together properly.
Even with a tripod and remote, you may be getting some camera shake. If your camera has a mirror lockup or exposure delay mode, use it to damp out the mirror slap. If your camera doesn't offer either of these, try using the self-timer.
Also, make sure your tripod is sturdy enough. It's a heavy lens, and even if your tripod holds it, it may not be holding it very steady. Try putting your camera on a tabletop and shoot something at the other end of the room and compare the results.

I can't figure out where the three filters are installed. I have skylight, nd-2x and 4x

The filters attach to the back of the lens. Remove the lens from the camera. Look where the lens fits onto the camera. Inside you'll see the screw threads that match those on the filters.

Put the lens on my nikon d70 wrong, now I can't

If you can't remove the lens using the lens release button and gentle force, take it to a camera shop or send it to Nikon for service. (That way, if the camera does break when attempting to remove the lens, they are responsible for fixing it.)

How do I fit the Hoya UV filter that I have been sold with my New Nikon D3100?? Darent be too heavy handed as new to this. Thanks.

The filter doesn't go onto the camera, but onto the lens. Assuming it's the proper size, it should just screw into the threads on the front of the lens (the end away from the camera). If the lens hood is on, remove it first.

My D80 fell from a foot n half above the ground level well packed in a good quality carry case few days back.uv filter attached to 18-135 Nikor lens cracked & lens cap was jammed. After carefully...

Hi, allow me to suggest using another lens to see if you still see the dark patches in the top corners. If not it is the lens, if so it is the camera. Either way it sounds as though something is maladjusted. Call Nikon digital 1-800-645-6689.

Dont know where filters go for Quantaray mirror lens 755035

That lens takes a 77mm filter - if you examine the end of the lens very closely, you'll see some threads just on the inside lip of the very edge - the filter screws on to the end via those threads.

Lens Protection Size!!!

Get a CLA-1 lens tube. It screws into the camera body. The other end accepts 43mm accessories. Put on a 43-49mm step-up ring. Into that screw a 49mm UV filter. (The step-up ring is needed to separate the filter from the extended lens.) Leave the UV filter on at all times. Throw away the lens cap.
