A few items impact the visual quality of the images you see in your telescope.
As strange as it sounds, if you’re trying to view distant galaxies and the Moon is super bright, it will impact your viewing.
Super hot weather and the heat rising from the Earth will impact your viewing if you’re looking close to the horizon.
Light pollution shouldn’t be underestimated. City lights, urban lights, and even Elon’s satellite train will impact your ability to capture pristine viewing. The satellite train will go away shortly, but consider heading to a location with less light pollution for better viewing.
A cloudy night can put a damper on star viewing. If the clouds will be coming and going, it might still be a good night for star gazing between clouds.
