Question about Optics
Astronomical telescopes normally do show an inverted image, as light-gathering power is more important than orientation, and the inclusion of more internal glass-to-air surfaces adversely affects this. The only times you may find it an issue is when you look at either the Moon, or Jupiter - for all other purposes it is fine.

SOURCE: red dot finder scope
Simple-- you can also do this during the day on an object at least 100 yards away-- but at night; get the moon centered in the eyepiece and without moving the telescope center the red dot on the moon. This will get you almost aligned-- then put a bright star in the eyepiece and readjust the red dot to center the star.

The image of all astronomical telescopes are upside down (SCTs are upside down and reversed). RACI (right angled, correct image) finders do produce a right-side up image. For daytime use a erect image prism eyepiece.
Follow below instructions (except 7 in your case)
