It is normal for astro telescopes to show an inverted image. It may seem odd but this is the case. It does not matter when viewing stars, but occasionally it is a problem eg for lunar viewing.

Therefore, and for land "terrestrial" viewing, you can fit in an "erecting" or "correct-image" prism

There are many brands, some more expensive, for photography

in order to install another year motor in your car you need all the computers and modules the 99 corolla motor has that make it run ... now you have a harness in your car now that was set up for 2000 1.8 prism motor you need to know how to merge the two harnesses together to make the new motor run... like getting the right powers and ground and signal wires to send right info to power up computers and modules for the corrolla motor

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.

Turn the diagonal, and the image rotates. Using the scope for star gazing it does not matter. Normally an astronomical telescope shows an upside down image--- no up or down in space. The erecting prism is only used for terrestrial viewing as the prisms inside are probably NOT multi-coated.

there is a regular schedule but I change mine when I star seeing my fuel mileage drop ,

You do not need an erecting prism to view objects at night. These are used if you wish to view terrestrial objects since it turns them right side up.

If you have a reflecting telescope (it uses mirrors) it's normal to not use an erecting prism or as they are also known as star diagonals. Objects will appear inverted and that's normal. A refracting telescope (no mirrors, just lenses) will also invert the image but it is quite often used with a star diagonal to make it easier to view. There are many other types of telescopes that use a combination of mirrors and lenses.

I hope this helps.
