It should be noted that, the final image of object (such as stars, planets or satellites) formed by an astronomical telescope is always inverted with respect to the object. A telescope with two convex (converging) lenses is a Keplerian telescope. The eyepiece forms a real image of this line. Keeping that in mind, it's still very counterintuitive that despite Hubble having a cumulative cost north of $10 billion, this amateur setup of under $10k (guessing) does extremely well next to it. An astronomical telescope is a refractiong telescope that consists of two convex lenses - the objective lens and the eyepiece. The minus sign tells you the image is formed on the "wrong side" (left in the image) of the lens, i.e., it is a virtual image. The distance between the objective and the eyepiece is 101 cm. Fully adjustable left and right Fully adjustable up and down How to use a red dot finder?
