Astronomical telescope for observing deep space
In fact, you don't need to take pictures, and you don't need to choose AP0, an achromatic high-end mirror (unless, of course, you have extremely high requirements for imaging quality). It is suggested to consider a common refractor with a diameter of 120 mm, which has higher imaging accuracy than that of reflection, and the reflective film is easy to fall off, so it is troublesome to re-coat it in a few years. Generally, it is not recommended to choose reflective type (although its aperture is relatively large).
Sirius, Guanbo and AstraZeneca in China are all very good. Suggest Sirius's painter series, about 3000 yuan, good imaging, 80mm caliber is also suitable for novices. In view of your high budget, Sirius Danqing hand ED series mirror is the best choice, with high imaging quality. The price is less than 5000 yuan. This is the official website of Sirius. You can refer to it:/These mirrors are refractive, so it is absolutely more than enough to survey the sky with such equipment.
General astronomical telescope, 60 mm in diameter, costs less than 1000 yuan. This thousand yuan mirror can be purchased online, but if you choose high-end products, you need to go to a physical store to avoid unnecessary trouble caused by damage in transit.
Last but not least, I have to remind you, how enthusiastic can you be about buying astronomical telescopes? If you spend a lot of money on impulse and watch it several times, you will be bored. Wouldn't it be a pity to throw away thousands of dollars of mirrors? Therefore, I suggest that you don't "do it in one step", buy an entry-level mirror for several hundred yuan first, and then make further upgrades.
