QHY CCD POLEMASTER 

  • PoleMaster - a high precision, easy to use electric polar scope
  • Mount adapters optional (see recommended accessories)

Achieving a high precision polar alignment is not an easy feat. You may spend a lot time on it yet you do not know if it is really well aligned and you never know how good it is aligned.  After you get everything ready and begin taking exposure, you touched the mount by accident, you have to restart from the beginning, perfrom polar alignment, three star alignment, goto the target and begin taking exposure again. You may waste another hour to do that and to your dismay you realise the sun is rising...

PoleMaster is a new invention of QHYCCD and it can solve these problem perfectly. It gives you a direct and simple way to align with the pole. Within  two minutes you could obtain very high polar alginemnt precision up to 30 arcsec.

TECHNOLOGY OVERVIEW

How to get the pole well aligned. The simplest idea is just to find the true north point and match its position with the rotation center of the RA axis. QHYCCD's PoleMaster employs this idea. This device can be installed on front of the RA axis,  It use a highly sensitivity camera to capture the image of northern sky. The sensitivity is much higher than the naked eye, so it can see not only the polaris but also some faint star nearby. Based on the locations of these stars, it can calculate the position of the true position of north pole.  With some sophisticated methods the PoleMaster can also detect the rotation center of the RA axis. It will mark the two point on the screen, one is the RA rotation center, another is the virtual polar point. You can adjust the mount and let them overlap then the pole is well aligned.

FAST, EASY AND COMFORTABLE

You do not need to rotate the telescope to some positions to allow the polar scope to see the sky. You do not need to lie down or squat to adjust the mount. You do not need switch off all the lights and observe through the polar scope carefully to find the pole star. You do not need to input the date and time, rotate the mount to a strange angle. you do not need to adjust the  horizontal balance  anymore.

HIGH PRECISION

The pixel resolution of this PoleMaster is approx.. 30arcsec/pixel.  The image sensor itself can be regarded as a good ruler. Much more precise and sensitive than the naked eyes. In best condition, it can get pole precision down to 30 arcsec.

WIDE FIELD. EASY TO FIND THE NORTH STAR

The PoleMaster has a 15*10 degree field of view. You can find the north star easily.

Can be installed on any mount. PoleMaster can installed on any mount with a suitable connector. Even your mount has no polar scope, that doesn’t matter.

POLE MONITOR/ALIGN AT ANY TIME

With PoleMaster you can monitor the polar alignment at any time. When the mount is moved by accident, you can adjust it back directly without redo the whole process.

NO NEED 3-STAR CALIBRATION ANYMORE.

After done aligenment by PoleMaster, your mount does not need 3-star calibration anymore. Just using the 1-star calibration or single star sync you can get your mount ready for GOTO.

Dit is werkelijk een super ding!!
Na het instellen op de pool met de EQ8 heb ik zonder guiden een opname gemaakt van M51 met sups van 10 seconden. Na een uur stond M51 nog exact op dezelfde plek.

Beoordeling: [5 van de 5 sterren]

De bedoeling was om de polemaster te gebruiken op mijn reismontrering, om er mee te leren werken eens op de mesu 200 gezet, binnen de 5 minuten stond de hele boel op de pool uitgelijnd. Sneller dat de PHD2 driftmethode, en nauwkeurig genoeg, testje, 60 seconden op 2000mm fl was perfect zonder te volgen. Een echt fijn product!
