Is the black hole harmonic equatorial meter accurate?

Hello, are you asking if the black hole harmonic equatorial telescope is accurate? The black hole harmonic equatorial meter is accurate. The black hole harmonic declination instrument adheres to the design concept of "making celestial photography easier", with a weight of 3.4kg and a load of10 kg; No heavy hammer; The integrated shell is very similar to rst- 135, and the equatorial telescope has high rigidity, which ensures high-precision star guidance. Innovative latitude and longitude seat design, 0 ~180 adjustment, without polar axis calibration process; German equatorial telescope+theodolite switch mode with one button, so that observation and shooting can be arbitrary; With dovetail electrical interface, zero bubble is convenient for users to install and find zero position; With the upright post and tripod with horizontal adjustment function, the equipment can be easily installed to enter the combat state within 5 minutes, so the black hole harmonic equatorial instrument is accurate.
