TOPIC: INDI/Linux driver for the QHY Polemaster, developers needed.

It's already working with INDI, no need for additional software. If you want to use Polar Assistant tool under Linux, you can use Ekos Polar Assistant.

Not sure how I missed this. I will definitely be giving this a try with the RPI3 next time skies are clear.

How do I configure for the Polemaster camera to work with the Polar Alignment?

Setup:
1. EdgeHD11 - 2800mm FL
2. ASI1600mm
3. ASI224MC
4. Polemaster
5. using OAG

Issue is that the pole alignment cannot be started due to the FOV reported when combined with the 2800mm focal length.

Is there a way to setup correctly with the polemaster?

Thank you

You could perhaps use the "Guide Scope". So even if you do not have one, adjust the Celestron "Guide Scope" so that whatever focal length you put there results in the correct FOV for Pole Master. Then from Align tab, you can select "Guide Scope" and FOV will be updated accordingly.

Yes, this worked for me in my test!

The primary scope is defined and now used for both imaging and guide camera. The guide scope is now fictions (120mm aperture and 480mm FL) and used with polemaster.

Now I just need skies... oh where did they go?

Hi Jasem

How should I configure Ekos, in order to use my Polemaster for polar-alignment?

This is my setup:
Skywatcher NEQ-6 Pro
Imaging scope: GSO RC6 with Canon 650D (FOV = 0.93° x 0.62°, FOV with 0.64x reducer = 1.45° x 0.97°)
Guide scope: TSL60D (60mm aperture, 240mm focal length) with ZWO ASI-120MM (FOV = 1.14° x 0.86°)
Polar alignment scope: QHY CCD Polemaster (FOV= 11° x 8°)

Best regards

In this case I suggest you create an equipment profile dedicated to polar alignment routine. Select the guide scope as the polar alignment telescope, and guide camera as QHY. Then in Alignment module, select "Guide scope" and of course the guide camera and proceed.

Hi Jasem

Thanks for the quick reply! That's also the procedure I arrived to, but it would be VERY nice if it was possible to configure more than two scopes for a single equipment profile! Would such a feature be hard to add???

A second question regarding equipment profiles and equipment configurations, is it possible to export the profiles and configuration data, so it can be imported again later i.e. after a re-install or on another device e.g. from a PC to a Raspberry Pi? It's OK if I need to do it by hand, but where do I find the correct files? An automatic import/export feature would of course be preferable...

Best regards

Yes such a feature would be difficult to add because 99% of the users have either 1 or 2 scopes for a particular setup. Support N scopes would be possible, but it's too much work for such little gain IMO. If you really feel like you want that, we welcome code submissions!

Regardsing the data, it's all stored in userdb.sqlite file located under ~/.local/share/kstars

You can move this around between computers so consider it as the export/import mechanism. There is no "merge", if you move it to another computer which already has userdb.sqlite, you have to overwrite what you have there.

I can see that I can actually make different scope configurations in the EQMod driver, it seems to support up to 6 different (Main + Guide scope) configurations.

It just seems to be important that the equipment profile selection of primary + guide scope matches that of Config#1 else it will be overwritten... when connecting to the equipment.

Using this approach I don't need to use different equipment profiles, which would require me to disconnect and re-connect to all my devices including the mount, when switching between the different use cases (Polar Align, Imaging without reducer, Imaging with reducer, etc.)

Would it be possible (and worth the effort) to add support for switching between these (max 6 scope configs) in the Mount tap in Ekos? It already displays the scope data for the currently selected scope config, and it updates just fine when I switch to another config in the INDI control panel. But it would be much more user friendly to be able to this from the Ekos mount tap directly! Just a suggestion ;)

It's done in GIT now.

Hi Jasem

I just updated ekos and indi from the PPA, but I can't see any change in the Ekos Mount tap... Any chance that your change in git hasn't gotten into the PPA yet?
