Curated by NightSkyMario — astronomy educator, outreach guide, and lifelong stargazer. Eyepieces that come with most telescopes sometimes aren't the best. An eyepiece upgrade is almost like getting a new and better telescope, and seeing is believing.... per inch or 2 x per mm of aperture. For example, a 130 mm telescope has a limit of 260 times and a 8 inch telescope has a limit of 400 times. If you go beyond that, your image will blur. Magnification is determined by Telescope Focal Length divided by Eyepiece Focal Length. For example, if you have a 650 focal length telescope and you're using a 10 mm eyepiece, your magnification is 65 times.

Moon filters

The Moon is shockingly bright through a telescope and it will destroy your night vision. It's also very hard to look at a bright Moon though your telescope. A Moon filter will help cut down on the glare and save your night vision.
