After several years use without
I fear these have suffered damage without your knowledge. The collimation has gone bad, hence the two images instead of one. As the left side doesn't focus properly, I would guess that one of the prisms in that side has shifted position, which would account for both defects. This can be fixed by a skilled and knowledgable person, or made worse by someone who does not know what they are doing, but in the end, it may be too expensive to have them put right by an expert, as very good binoculars are available quite cheaply today.
Does it matter at what magnification i use when
no it dont but it would be far better if you test fired your gun till you could shoot by gessing the hold over/hold under anf forget about the bam silly mil dots they will only be right on the gun they were set up on and no two guns shoot the same so you see the mil dot is a bit of a con realy
Manual for barska telescope 114900
You will not find a manual for that scope. BUT! It's a small equatorial mounted REFLECTOR telescope. Meade telescopes has a similar model and a manual. They all assemble and are used in the same way.
Look on this web site under REFLECTOR for a scope similar to yours and download the manual and print it.

Your scope should be very similar to this one:

One side won't focas
You don't say what model binoculars you have, but there are two possibilities (well, three, but the third one is that your binocs are broken - lets try the other two first!)
Some very fine binoculars have individual focusing for each eyepiece. You focus each side for your eyesight. If that's the case with your binoculars, there won't be a central focusing control.
If you DO have a central focus knob, it's possible that your binoculars have a "diopter" focus on one or the other eyepiece. Look at the rim of the eyepiece for a marking that looks like "+ . . . | . . . -" or something similar. What you want to do is focus the binocs using the central control so the the UNMARKED eyepiece is in focus for you (close one eye to focus), then switch eyes and focus the marked eyepiece by rotating the eyepiece rim until both eyes have good focus.
Binocular manufacturers do this because many people have better vision in one eye than the other, and many people also prefer to use binoculars without their glasses. Hope this helps.
Cross hairs do not adjust. Tell me what to do please?
All question need FULL 'make model (what it is)'.
You posted to optics, so let's guess is a telescopic rifle sight?
It is impossible to see and movement as the crosshairs move such a tiny amount. Half a millimetre in the sight is 10 feet at the target. The only way to zero in sights is on a fixed bench rest at the range.
If you really think they are faulty, return them to the maker for repair.

I have a NexStar 90GT with no hand control, a replacement will cost $135, is it worth it to buy for this telescope?
Whether or not it's worth it to buy a replacement hand control for your NexStar 90GT telescope depends on a few factors:
- How often do you use the telescope? If you use it frequently and rely on the hand control to find objects in the sky, then it may be worth it to invest in a replacement.
- How important is the hand control to your observing experience? If you're comfortable manually finding objects in the sky and don't necessarily need the hand control, then it may not be worth the expense.
- Can you find a cheaper alternative to the official replacement? Sometimes, third-party sellers may offer hand controls that are compatible with your telescope at a lower price.
Ultimately, it's up to you to decide whether the cost of the replacement hand control is worth it based on your individual needs and preferences.
