Can be seen in messier. For most nebulae and star clusters, a magnification of 50 times or less is enough. For Orion nebula and Andromeda nebula, 20-30 times is more suitable. The larger the aperture, the brighter the shape. Such as multiple stars, variable stars and comets, beginners can see many such stars with telescopes. But comets only need to be close to the sun to be seen. Therefore, it is recommended to use a larger eyepiece when looking at nebulae and clusters.
