DSLR Camera for astrophotography


I currently have a 90/1000 star tracker refractor telescope with manual equitorial mount. i’m planning to buy a dlsr camera to capture the images through the telescope for astrophotograpy. currently im using my mobile phone to capture the telescope but the images are not that good for planets and nebulae. So someone can recommend me a good camera for astrophotography through the telescope. Budget is around 30K.
