Page 2 - The "easy-view image screen" is not a lens eyepiece. It uses a frosted piece of glass like a screen for projecting the telescope's image. It will have a significantly different focus and the image magnification will be equal to the telescope at prime focus without an eyepiece. This number is equal to a 25.4mm EP at f13.5 750mm focal length with an aperture of 60mm. (750/25.4=29.5x.)
Page 3 - The tiny round "adapter appearing" object next to the word "sidescrew" is the supplied dust cap to be removed.
Page 4 - The two triangular humps work well for finding daytime objects but are mostly invisible when trying to find night objects. The technical name this optics-less sighting is Two Line-of-Sight Protrusions (Protuberances) on the OTA.
Page 9 - The supplied 20mm eyepiece will not fit in the back of the telescope without the angled image erector. The eyepiece is 1.25 inch and the back of the telescope is 1-inch (25.4mm). The image erector is needed to use standard 1.25-inch eyepieces. The international standard microscope eyepiece tube diameter is 23 mm or about 0.9 in. With a different of 2.4mm, tests could be made with microscope eyepieces without the 90-degree image erector to experience the inverted image.
The 90-degree Image Erector uses an AMICI prism. An Amici prism directs the light path inside a telescope and inverts the image to create a comfortable observing position. This image inversion feature distinguishes the Amici prism from a zenith mirror. With the Amici prism, the image is no longer upside down, so that the telescope can be used for observing nature. An Amici prism also makes orientation easier when observing the Moon. Amici prisms are only useful for lens telescopes (refractors), Schmidt-Cassegrain and Maksutov telescopes. An erecting lens is required for a Newtonian telescope.
The Acuter Maksy 60 uses a special 90-degree Image Erector with a custom 1-inch diameter on the telescope side and a standard 1.25-inch on the eyepiece end. The 90-degree diagonal features an image erecting Amici prism that allows you to look into a telescope at a 90 degree angle. It produces an image that is oriented properly, which means that the image is upright and correct from left to right (i.e., a correct, non-inverted, non-reversed image).
