What's the difference between 70400, 80EQ and 90EQ of the AstraZeneca Astronomical Telescope? Please give Daxian a detailed answer. I want to start with one.

Different models, different appearances and different functions ~ ~ All three models are refractive.

70400 caliber 70 mm but short focal length is not suitable for watching astronomy ~ suitable for watching! This guy is small ~ although the caliber is 70, the short focal length is limited! The three cheapest models are around 300 yuan.

80EQ！ 80 mm EQ refers to a device with an equatorial telescope (the equatorial telescope is a device that can overcome the earth's rotation without affecting observation), which is recognized by experts as an artifact. This mirror is around 830 yuan, but the tripod is unstable!

90EQ caliber 90 mm This is an upgraded version of 80! The price is around 1500 yuan!

See how much Mimi buys!

Generally buy more than 80EQ! 90 is more expensive! And the performance is a little better than 80. It is not recommended to buy 90! If you want to be better, you can consider buying a mirror with Cinda Xiaohei 150/750. The price is about 2200 yuan, much better than 90!
