The good news about astrophotography is that you don’t have to max out your credit card to purchase the most expensive DSLR possible. What you need the most is a good DSLR, wide-angle/fish-eye lens and a tripod.
Among them is the Canon 800D, which boasts a 24.2MP APS-C CMOS sensor and a DIGIC 7 processor capable of capturing a decent low-light performance at up to ISO 25,600. Weighing 532g, the DSLR is also reasonably lightweight. Meanwhile, its articulated 3.0-inch vari-angle touchscreen display also allows you more creative freedom to shoot pictures at various angles.
