Excuse me, can 4SE and 5SE geodetic theodolite be replaced by equatorial theodolite?

I don't know, okay? I heard that theodolite can't track? With the stars? Both warp and weft should be adjusted.

Can the equatorial plane be aligned with the polar axis and then only adjust the right ascension? There is no need to adjust the deflection angle

The equatorial plane must be used for deep space photography. And be sure to bring a star guide interface!

There will be a field rotation when the theodolite is tracked for a long time. More suitable for visual inspection!

No photos? Jingwei is more convenient ~

There must be an equator when taking pictures ~

Theodolite? Equatorial instrument? Nothing can be less. ?

Theodolite is simply understood as a platform that can only rotate up and down, left and right.

The equatorial plane is simply understood as a support rotating parallel to an axis, which is called right ascension; Among them, there is also a rotatable platform on the bracket, which is called deflection angle.

I don't know if this is right.

Astronomical long-time exposure photography must be tracked by equatorial telescope.

The theodolite is stationary relative to the earth, and the equatorial plane is stationary relative to the celestial body. The theodolite uses the latitude and longitude of the earth, so when you look at the scenery, it is still. ? The equatorial plane uses the right ascension and declination of the celestial sphere. The celestial sphere does not rotate, but the earth rotates. Therefore, after the earth's rotation is offset by the equatorial plane, celestial objects can still remain static in the field of vision.

Theodolite is more suitable for portability, and theodolite with goto is only suitable for visual inspection, and the photography accuracy is not enough!

The equatorial plane is more suitable for photography, of course, it refers to the high-precision middle and high-grade equatorial plane, such as EQ3-D, HEQ5 and so on. The disadvantage is that it is heavier, because in addition to the mirror weight, there is also a counterweight!
