Hello 'chino, Welcome

The image will be upside down and reversed left to right, thats normal. Looking at the link you posted, the findersope is facing the wrong way also.

Don't worry too much about the upside down reversed image. When you look at the stars it doesn't matter and you will get used to the required movements to centre objects soon enough.

Start with you lowest power eyepiece without barlows (lowest power is the highest mm number) this will help you get started. In your case that will be the 20mm eyepiece without the barlow or 1.5x erector, that will give you 35x magnification (approximately) Magnification is focal length of scope divided by fl of eyepiece eg. 700 divided by 20 = 35x

(ingore this at the moment but as you read more it will make sense: The information given in the scope specifications is a bit misleading so I can't give you the exact magnification. The scope is listed as a 700mm x 76mm F7.9 but at 700mm with 76mm aperture it comes to a focal ratio of 1: 9.2 or conversely if it is a 76mm F7.9 the focal length will be 600mm, as I said this does not matter at this stage)

Just point it at any part of the night sky and enjoy your new window to the distant past.
If you are setting up in the daytime do NOT point it anywhere in the direction of the Sun !!!!

The erecting eyepiece will flip the image you see back the right way up and will also darken the image a bit.
Cheers, Matt

Hey an UPDATE.

Not sure what that Erecting Eyepiece is for. But I took that out, and now only got the 20mm lense in there. And now I can see light, well a blue sky so far. Gonna try point at some trees and see how it goes.
