Say goodbye to the knee/back torturing polar alignment nights
Many of us have faced varying degrees of challenges to polar align our equatorial mount. 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.
PoleMaster is very simple to use. 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. Overlap these two circles and you are good to go. The entire alignment procedure can be done in 5 minutes while some of our users have done it in shorter duration.
How simple is it to use PoleMaster? Deadly simple.
Simply follow the steps prompted by PoleMaster software and you will have a very precise polar alignment.
Polar alignment without neck pain, ankle and muscle strain
With PoleMaster, you can do polar alignment at the comfort of sitting on your chair and looking at your computer screen. Cruching down and trying hard to peek through your polar scope is now in history.
Accurate to 30 arcseconds of true north pole
PoleMaster will first prompt you to do center axis calibration and then rough alignment which yields an accruacy around 5 arcminutes. 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.
Allows more accurate tracking with portable tracker limited to single axis autoguiding
Portable star trackers such as AstroTrac's and Star Adventurer do not have motor on the DEC unit. 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. 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.
Some hard facts:
|Field of view||11º x 8º|
|Rough alignment accuracy||5 arcminutes|
|Fine alignment accuracy||30 arcseconds|
|Computer interface||USB 2.0|
