Is it any special fat for the Telescope focuser--To getting it going easy and smooth---?

With the hexfocus on your telescope it does not really require grease but making sure everything is adjusted properly will be good.
Make sure the focuser tension is not overly tight.

Is your focuser not smooth ?

Adjustments screw...just the focuser need some adjusting...personally i would avoid any lubricant for the telescope focuser.

The focuser is tight and firm its no problem with that,i just thought it was some fat ,,on the diagonal threads plate for moving the focuser,,but maybe its some conservation oil or film that got very sticky off time-----anyway metal against metal isnt never god,"friction and weardown",so any sort of thin maybe oil or little grease is maybe god anyway..just a little little easy flowed grease ..

Sounds good!

In this picture is a Greyford style focuser 70mm Altair Astro

If I understand correctly, a focuser with diagonal thread plate sounds like a rack and pinion focus.
If this is the case I have found on my rack and pinion focuses sometimes some grease that has gotten stiff. I would clean it off and if you wish to lubricate it, understand that any lubricant will collect dirt.
The flat bearing plate of a crayford focuser should not be lubricated as I understand it.

Fine tuning the tension adjustment, as Moriosi has mentioned, may be your best approach.

But I would certainly clean off the stiff fat.

everytime i move the foscuser forward and backward.and when ut comes to a certain position .is sounds sclt schlt schlt--so i will change the sticky fat..
