Works at both northern southern hemisphere with atmospheric refraction correction.

The original polar-scope was very poor, and I simply could not collimate it accurately enough.

Astrotrac should simply offer this as an option The tracking performance of Astrotrac is excellent once aligned, and your adapter allows me to do this quickly, and without much effort.

Be it neck pain, stress on the knees or accidentally kicking the tripod, you must have had some of these frustrations down the road.

PoleMaster allows you to do polar alignment at the comfort in front of your computer to a high degree of accuracy.

While it will not help you align your mount mechanically, you can easily tell the true north position from your screen and adjust your mount accordingly without squatting, kneeling or whatever difficult pose to look through the polar scope.

Polar Alignment Camera Software Will Do

Simply attach it to the RA axis of your mount with mount specific adapter, with Polaris and the surrounding region visible, PoleMaster software will do a plate solve and show you the current pointing of RA axis and the true north position.

The entire alignment procedure can be done in 5 minutes while some of our users have done it in shorter duration.

Use your keyboard arrow keys or mouse wheel for fine tuning.

Cruching down and trying hard to peek through your polar scope is now in history.

Next, you will be asked to do fine alignment which PoleMaster will plate solve against the known stars.

The accuracy after this step is approximately 30 arcseconds, much better than most polar scopes 120 arcseconds (2 arcminutes) accuracy.

Therefore, the tracking error in the DEC axis caused by poor polar alignment can not be guided out.

An accurate polar alignment could virtually eliminate the drifting in the DEC axis.

Polar Alignment Camera Portable Trackers And

Combined with autoguiding in the RA axis, you can dramatically improves the tracking performances of these portable trackers and enable the use of even longer focal length lens or longer exposure.
