Both my HEQ5 and EQ6-R have belt drives (I modded the HEQ5 myself) and no noticeable backlash. This is just FYI of course ;)

A few months ago I bought a SkyWatcher EQ6-Pro and it has been performing very well. Guiding RMS well within 0.6” using a 60 mm F=280 mm finder scope and an ASI120MC-S guide cam. Before that I used a borrowed AZ-EQ6 (not the 5 that you are considering) and it performs very well as well. The EQ6-Pro has a lot of improvements over the previous EQ6 models plus belt drives which is why I bought that one. Both mounts I controlled via INDI through an EQDir cable and the EQMod driver.


HTH, Wouter

I used to get the same error when the build directory is created inside the KStars source directory. If you created it along side of it the error disappears. By the way, it isn’t stated with so much words, but the install or readme or whatever it is called does suggest to not put the build inside the source directory but I had to read it several times before I realised this.


Cheers, Wouter

I tried just now and on my camera the cooler doesn't work at all and I am sure it did before. However, I never had to actively enable it. It would always start cooling down to 0 degrees Celsius without a problem. Now when either in the INDI Control Panel or in the CCD tab I click on the "On" button for cooling it automatically switches to off again. Logs attached.

I answered to the other topic that you opened. Would you like to continue there since it is more dedicated to your specific observation or continue here?

I haven't checked the cooling of the chip with my QHY9 and the latest driver and will do so tonight. So far I have only checked if the filter wheel works and it does with this driver. To be continued!

I confirm that my QHY9 CCD camera and filter wheel work with this SDK. Thanks very much, Jasem!

I may not be the right person to ask advice about spacings because I have had a bad experience myself. According to the vendor the backfocus was 55 mm. I am using a DSLR camera and with the T2 bayonet on it, the distance from the flattener to the sensor was exactly 55 mm. However, the stars in my pics radiated away as well. So I tried 4 mm and that still wasn’t enough. I spent three nights increasing the spacing with steps of 0.5 mm (no kidding, I really did that) only to find that I needed to add 24.5 mm (!!!) to get the correct spacing. And I am still not satisfied since the stars are not completely sharp in the corners. Oh well, I hope you won’t have to go through such an exercise.

From your comment it looks to me that you are on the 55 mm but I really think it is not enough. How’s your German? See

The first image (Bild A) shows what the stars look like if the spacing is too large, the second image (Bild B) when it is too small.

Beautiful images. I particularly like the brown hue in the Merope Nebula. Well done! And congrats on having had a successful fully automated session! This is where Ekos and INDI prove their value!

If you don’t mind me asking, are you sure the backfocus of the camera is correct? Perhaps this is due to the low resolution of my iPad, but it looks like the stars in the corners of all three images are slightly elongated and are radiating away from the center. You may need to add a tiny bit between the corrector and the sensor but once more this could be due to the representation on my iPad.


Clear skies, Wouter
