The eyepiece size (diameter) is the standard 1.25 in. Erecting eyepiece adapters can be used with this scope. maximum magnification is 250x therefore highest eyepiece would be 3.6mm most useful magnification of any scope is 150x (900/150= 6mm eyepiece Eyepieces provided with scope (Huygens type) have a narrow field of view and are relatively poor for astronomy but should be fine for terrestrial viewing
Astronomical telescopes usually show an upside down image. There is a good reason for this- erecting the image needs more bits of glass in the light path, which reduces the amount of light and increases aberrations. Even if this is only slight, astronomers prefer to avoid it, and they don't really care which way up the Moon or Jupiter appear.
It is possible to fit an erecting prism or eyepiece to most astronomical telescopes, and some of them come with one, but if you want a telescope primarily for terrestrial use, you are much better off buying what is called a "spotting scope".
If the telescope has a standard 1.25 inch diameter eyepiece, then an erecting eyepiece may be found on Amazon or eBay. An erecting prism or diagonal of the type that bends the light through 90 degrees is not right for a reflecting scope. These are used on refractors.
NO, you do not need a diagonal. The eyepiece goes directly into the focuser.
images in astronomical telescopes are always INVERTED-- you can buy an "erecting prism diagonal" for terrestrial viewing, but it is not needed for star gazing.

This is an eyepiece attachment that goes in between eyepiece and telescope. I found only two items on ebay.com (different size/fit), searching on "eyepiece erector".
All astronomical telescopes show the view upside down. it is the properties of the mirrors/lenses. Ther is no up and down in space. You will get used to it. For terrestrial viewing, you can buy a erect image diagonal (for refractors and SCTs) or a erect image eyepiece for refractors. This is not recommended for astronomy since it reduces contrast.
This is an imported telescope probably from China. You will not be able to contact a manufacturer. Never buy a telescope off of Ebay, at a garage sale, from Wal Mart, or craigslist, unless you know exactly what you are buying.
Buy from either a local telescope shop or online from reputable retailers like these:

Your scope appears to be on an equatorial mount which must be polar aligned in order to be used. Google "polar alignment" and learn how this is done or read my TIPS on my profile page.
Eyepieces come in 3 sizes .975, 1.25, and 2 inch. Measure the hole in the focuser. Any of the retailers listed above can sell you an eyepiece.
Also log on this web site and read the forms-- for lots of information:
All astronomical telescopes show upside down images, you must add extra glass to erect the image which will dim the images of deep sky objects in the eyepiece.
You can buy an "erecting" prism for terrestrial viewing.
Probably NOT actually pointed directly at the moon-- you should have moved it around a little -- the moon was probably just outside the field of view through the eyepiece. ........................ telescope must be pointed DIRECTLY at the sky object-- also use the eyepiece with the largest number written on it=== this gives the LOWEST magnification..... and a slightly wider field of view.
