Observation on the use of the target in the solar system by anti-Tian-wang (i.)

Just a summary of self-experience, there are many places to learn to practice

I use the equipment is 150/750 cow anti, equatorial instrument electric with tripod

Let's talk about the use of the sky I know.

A pair of polar axes

Take out the lower body of the sky looking, do not install heavy hammer, this is very light

Placed to the point of observation, to the polar axis. Polar mirror, drift, I've never used it.

My approach is simple and practical, and does not require special precision. Using the app on the phone, I use the star Wlak, very useful

The polar axis is the polar axis pointing to true north (we're in the northern hemisphere, not half way)

Does not require extreme precision, so the polar axis point to the North Star is OK.

1. Adjust the latitude scale of equatorial instrument according to the latitude of your area first, do not know how much latitude to use the degree of Niang check

2. Point the Equator to the north, which is toward the approximate north direction.

3. Open the Sky app, according to the GPS will be in real-time location you can see the sky, with this and the obvious goal in the sky to, for example, the moon or Jupiter, the mobile phone lifted the target, the app in the corresponding target is coincident with the actual target in the sky, consistent with the location of the app is accurate, Then take the back of the mobile phone affixed to the polar axis mirror, the equator, so that the app in the North Star in the middle of the screen, repeatedly determine, adjust.

4. Adjust the level of the leg (tripod), my device comes with a bubble level. In short, the level is adjusted.

5. Insert the eyepiece or camera to start. From the camera screen generally can clearly see the polar axis of the quasi-alignment, if you feel special not allowed, can be adjusted.

Two optical axes

The bull is of course going to the optical axis. This and the polar axis have no sequencing, there are various methods. Calibrators I have been exposed to two types, one is the cross, the other is the laser.

Cross Silk is not very strong, laser is also good, although some people say this also has crooked, but I did not catch up, and itself is a small probability event bar. The importance of the optical axis does not have to be my wordy.

Find a goal

Using a star-searching mirror to find the target, inserting a large eyepiece in the eyepiece tube, I use 10MM, of course, do not add the barrow.

It's easy to find the target. Then adjust the Red meridian (manual or electric) to the target in the center of view. Then you can add the barrow to the center of the field. Then you can take the eyepiece off the barrow and plug it into the camera.

Shoot the planet, because the target is small, so add the appropriate multiplier of the barrow is necessary, if it is the face of the big goal of the moon, such as to shoot a straight coke that will not Gabaro, if you want to shoot Otsuki face or larger details, it is to add barrow

Just write it down here.
