New PoleMaster Electronic Polar Scope EQ Mount Polar Alignment Camera

Description

This product does not have an adapter ring. You need to purchase it according to your own equatorial model.
How is the electronic polar mirror mirrored to the polar axis?
'How to achieve the polar axis, the simplest and simple idea is to find the position of the pole of the northern pole, and then make it coincide with the center of rotation of the equatorial mount's right ascension axis, thus realizing the equatorial mount's right ascension axis and the earth's rotation axis pointing. Consistent. The PoleMaster electronic polar mirror of QHYCCD is the idea. The device can be mounted in front of the EIA's RA revolving axis. It contains a high-sensitivity camera that dynamically captures starry sky images near the northern celestial pole in real time. His sensitivity is higher than the naked eye, so not only can you see the North Star, but you can also see a few dark stars near the North Star. Based on the location of these stars, the software can calculate the true north pole pole position. In some ways, the PoleMaster electronic polar mirror detects the position of the center of rotation of the right ascension axis and then marks the position of the two points on the screen. All you have to do is adjust the equatorial mount, let the two points coincide, and the polar axis is right.
Performance
━━━━
High Precision
Wide Field of View
High Precision: The PoleMaster's pixel resolution is approximately 30 arc seconds. The camera's pixel matrix itself is a good ruler, so the accuracy it measures is much higher than the accuracy of the macroscopic lens. In the best case it can achieve an alignment accuracy of 30 arc seconds. Wide Field of View: The electronic polar mirror has a large field of view of 11 degrees x 8 degrees, so it is easy to find the Polaris.

Easy to install
Easy to install
You don't need to rotate the telescope to some position to keep the optical polar axis of the equatorial mount unobstructed. You also don't need to squat down to see the polar mirror and adjust the equatorial mount. You don't need to turn off all the light sources to allow the naked eye to adapt to the darkness and look for the Polaris in the field of view. You also don't need to enter a good date, then rotate the equatorial mount to a strange angle, and you don't need to adjust the equatorial level.
compatibility
━━━━
Full range of adapter rings
Covering multiple equatorial mounts
EQ6/AZEQ6, HEQ5, iOptonCEM60, ZEQ25/CEM25, iEQ45, iEQ30, AZEQ5, Celestron AVX, CGEM, SX-4, TAK, MESU, SXP, UNC, EM200/EM11, EM400, EQ8, smart EQ, AP-SM, AP900, G11 ... Through the adapter ring, the PoleMaster can be mounted to any equatorial mount, even for an equatorial mount without a polar mirror.
Precision
━━━━
One star calibration
Tracking accuracy
Once you have calibrated with an electronic polar mirror, you only need to perform a single-star sync (one-star calibration) without Samsung calibration. Greatly facilitates the calibration of the equatorial mount.
real time
━━━━
Real-time polar tracking
Real-time polar axis adjustment
With the electronic polar mirror you can observe the alignment of the polar axis at any time, as well as continuously monitor the polar axis. When the equatorial mount moves inadvertently, you can also tune it back without having to redo anything.
This guide star curve is the result of a polar axis error test of the good polar axis through an electronic polar axis mirror. The test method is to disable the guide signals of RA and DEC. Then observe the drift in the DEC direction. The drift in the DEC direction will reflect the alignment accuracy of the polar axis. In this test, the DEC was almost a straight line in 10 minutes, and after 30 minutes of testing, it was found that the DEC drift was 1.5 arc seconds. From this, the accuracy of this polar axis alignment can be calculated to be 18 arc seconds.
