Could someone give me some recommendations for a good AP/visual telescope and image processing software?

I've got a Celestron StarSense Explorer LT 114AZ and a poor quality Motorola phone, the images i take are awful. If someone could please help me find a good astrophotography setup that is also decent for visual observing that would be great, i'm looking more into DSO's but planetary observations/images would be nice, I've got a budget of around 1,000-1,500 bucks. Also could someone give me suggestions on basic image processing and how to do that? i've just been editing images on Google photos since that's all i really know to do but i would like to do better. Thanks!
