I know nothing about that scope. Post some photos if you can.
Is this what you have?

That would give a Focal Ratio of 9.3 if I am doing my math right.
Well, compared to nothing it might be terrific. Are there better scopes? Well, how much money do you have? There are always better scopes.
If it has a 150 mm mirror and a 1400 mm FL, like the specs above, it could be quite good, assuming the optics are in good shape.
Your biggest challenge will likely be learning to use the equatorial mount. This is a little on setting up equatorial mounts. This may not be your exact scope or mount but it will be close enough.

I say, give it a try. Point it at something during the day and work with it in the daylight first. Remember that lower number eyepieces are higher power. So start with the highest number eyepiece you have and work your way down as you get used to the scope.
If you have a finder scope, get it aligned in the daytime. Get something centered in the low power eyepiece of the scope that is at least 1/2 mile away. I like to use the cross piece on a power pole or telephone pole.
Now adjust the image in the finder scope so that the object is centered. If the finder has a focus, get it focused. You will then be pretty close. Use the finder to target some objects during the day and see if they are within the view of the highest number eyepiece. That should be good enough for now, but feel free to go to the higher powered eyepieces and refine the targeting of the finder.
Now you are ready for night time.
Point it at the moon and get used to it on the moon. Learn to track the moon. Try the different eyepieces on the moon.
Try Jupiter if it is visible from your site.
But do all the set-up during the day and get used to using it during the day.
