QHY PoleMaster EQ Mount Polar Alignment Camera

The QHY eliminates the frustrating aspects that can happen during polar alignment. Save time with this highly sensitive camera! You can start polar aligning before the night sky becomes truly dark with its high sensitivity.

Simply mount your camera to the front of your RA axis, it will then capture an image of the northern sky and then calculate where true north is based on that image. The information is displayed on a screen, helping you make any slight adjustments if needed.

QHY PoleMaster EQ Mount Polar Alignment Camera-box

The QHY Polemaster is the perfect accessory for your system

Check out its features:

Accuracy: Your best polar alignment can now be achieved with a PoleMaster in the order of a maximum 30-arcsecond range.

Wide-angle view: The PoleMaster's wide field-of-view (11 x 8 degrees) makes it very easy to locate the pole star. 

Easy to install: Easily install it onto any equatorial mount through mount-specific adapters, even on mounts without a polar scope.

Real-time monitoring and adjusting: You can monitor your polar alignment in real-time. If polar alignment is lost, it is now a simple matter to bring it back without having to start from scratch.

Three-star alignment no longer needed: Once you are polar aligned, you will only need to perform a one-star alignment - a real time saver.

Pair it with a single axis mount: When used with a single (RA-only) axis mount, good polar alignment will minimize drift in the DEC axis, therefore maximizing the performance of your mount.

Great Camera for Polar alignment but...

I Initially I had problems getting it to connect, but finally got it to work. It should be focused when sent, but the first night all of my target stars that formed the grid that I needed to match with the alignment pattern were out of focus-large round faint discs that i needed to wait a while for the shy to darken to see. Contacted both QHY and OPT, but no information on the QHY website on how to focus the camera and neither were able to give me a link or information how I could. I was reluctant to dissemble the camera so returned it for another unit. Same problem with the next one! A search on line lead me to a video that explained how to focus the camera, ridiculously easy. In fact the camera is sent with a small Allen wrench for that purpose. I would give 5 stars if this information was available in the on line manual. Below is a link to a Utube video explaining how it is done.: https://drive.google.com/file/d/1Cr-BlQbrRlS_UARPpjhs7lnJHvMUjWSH/view It is not apparent that the cas will screw off, and I was very reluctant to remove some the screws on the base to take it apart and void my ability to return the camera. Fortunately I found it with the second camera.

Utility of PoleMaster is Outstanding

For portable-mount astrophotography, the PoleMaster allows polar alignment in the early evening, prior to creating a pointing model. Alignment using NextStar hand controller requires the model first and takes a bit longer. Initial impression, accuracy similar. But will test in future using PhD2 guiding assistant evaluation.

Slow refresh of Polemaster

The pole master software is very helpful and was easy to use the first time out. However, I am running Windows 10 on a brand new PC with an i7 processor and the refresh of the images coming through the polemaster extremely slow. I read articles online about the provided cable being bad and having to run a video through windows media player to speed it up. Haven’t used either of those solutions in the field as of yet but I did use another cable and it seems to be better, in the house at least. Not the greatest experience right out of the box.

Polemaster documentation is inacurate and out of date.

The installation instructions -- which I had to find on my own -- omitted all references to installing the driver. All hyperlinks in the manual, furthermore, did not work. Reading through the help comments, I discovered there is a new driver ... but it was contained in a reference to Dropbox -- making it not possible to download it. I eventually downloaded the driver from the QHYCCD site, although no instructions I could find mentioned the need to separately install the driver download. After installing the driver, I got the PoleMaster to function. Now I have to try the PoleMaster out this evening.
