Refractor telescopes can be used as "lenses" (but not reflector) for DSLR/Mirrorless cameras to get incredibly "zoomed" shots without spending $20,000 on a canon L lens. All you need is a T-adapter which for me was like $30.
Wider lenses allow longer exposures which allow more light / better quality shots. Once you hit a certain point, your stars will have tails which make it look less sharp / clean. To avoid, follow the 400 rule (google it). Wider lenses also get more space into your shot which looks good.
You can also embrace the tails you get with long exposures to great effect, by intentionally setting very long exposure times 30m, 1h, even all the way through the night 8h+. This produces shots with a "shape" to them as the Earth rotates on an axis and draws part of a circle in the sky with the stars. Can look amazing but since you need to do very long exposures there's very little room for error in this style. You can spend an entire night / morning on a single shot only to realise the settings weren't dialed in properly or you bumped it in hour 3.
Light pollution is your biggest enemy. If you live in a city, rip. Not to say you can't get decent shots in a built-up area, you're just fighting against it. I live in an area with terrible light pollution, but if I drive 30 minutes away there's practically none. The amount of interesting things you can actually see in the sky is dramatically better in comparion to sitting in a city.
Tripods are your friend. You need one full stop. Pair this with a remote shutter and you're golden. You can also buy very expensive astro tripods that have gimbals and rotate with the earth to completely avoid the stars producing tails. This is endgame kit for getting the cleanest, brightest shots.
Best fun I've had with photography. Good luck.
