Did not you see crashes of indi_script_dome in the INDI log on the Pi over time?

If a driver crashes, the process remains in zombie state and the INDI server starts a new driver process. It would explain this crazy long list.

Csaba Kertesz replied to the topic 'Living amongst the trees' in the forum. 2 weeks ago

@knro: Correct me if I am wrong, but I think the OP asks about a different thing. The Artificial Horizon expects to get polygons of the blocking objects, but OP has a very small FOV because of the trees. Basically, the red area on the screenshot is the visible sky and all the rest are trees. I think he wants KStars to "invert" the regions, having the defined polygon the FOV and draw everything else red.

@dokeeffe: Can you post more picture about your focuser? I don't see the motor on the photo in github. What kind of beagleboard/box did you use on the picture to assembly the whole thing together?

Csaba Kertesz replied to the topic 'EQMod tty read and write error' in the forum. 3 weeks ago

I use my Skywatcher Virtuoso mount with handmade serial-to-USB or bluetooth cable to connect with a RPi3. My experiences:

- The Bluetooth is not reliable enough to work with INDI. I think this is a general HW issue. You really have to find Bluetooth components with trial-and-error which work 100% reliable together.
- My wired cable keeps disconnecting and reconnecting the serial line after a few hours. Most likely because of the cheap USB-to-serial HW from ebay which most likely a fake Chinese counterfeit replica.

I think these problems are mostly likely related to HW all the time.

Csaba Kertesz replied to the topic 'Configure ekos for camera lens use' in the forum. 3 weeks ago

Hi,

I use my Virtuoso mount in two different configurations: telescope+CCD camera and only standalone DSLR camera. I found the alignment module in Ekos very sensitive to the calculated FOV based on the set focal length/aperture settings. Basically, the alignment fails if it is not accurate. Probably, I do something wrong, but the calculated FOV is all the time very off, if I set the real values. My method to find out a specific setting:

- Do a test image with the camera, upload to nova.astrometry.net. Check the FOV in the results.
- Play with the aperture and focal length settings, until the calculated FOV in the alignment module matches with the real FOV results from nova.astrometry.net.

Csaba Kertesz replied to the topic 'Skywatcher Virtuoso mount support in SkyWatcherMountAPI' in the forum. 4 weeks ago

The Virtuoso mount has a vertical drift which causes almost impossible to keep a target in smaller FOV (<1 degree) for a longer time. I implemented a software correction for this in the driver (SoftPEC). It seems to work great. The details and how-to is detailed on the usual page:

indilib.org/devices/telescopes/skywatcher-virtuoso-alt-az.html

The implementation should hit the bleeding-edge PPA today or tomorrow.

Csaba Kertesz created a new topic ' QHY5 camera and Raspberry Pi' in the forum. 4 weeks ago

This is FYI. Who may wonder why his QHY 5PII-C camera does not work on Raspberry Pi 3:
- after checking the USB cables...
- after checking the powered USB hub...
- after checking the AC adapter for the Pi...
- after checking with an other Pi board...
- after checking Raspbian and Ubuntu Mate...

...disconnect the ETHERNET cable and try again.

I just can't believe it: this CCD camera fails because the ethernet device sits on the USB bus. I replaced everything, tried even Ubuntu Mate, but the network cable was the culprit. D'oh!

To answer my own question, I checked with standalone DSLR. The arrow points down on the bottom of the plate solved image when it is projected to the sky in KStars.

When a camera image is used for plate solving, the result is drawn in KStars, but I don't understand, what kind of orientation does the small arrow mark on that image?

I agree that it is not the most important. But AFAIK the most valuable what an average amateur can produce and "scientific". Let me know if you have any better other ideas. I started to do my telescope project to do something scientific. :)

To my understanding, photometry of variable stars is still a way to produce some scientific data. That is why I started to build a robot telescope setup for my balcony a few month ago.

Csaba Kertesz created a new topic ' Viewing/converting FITS files from QHY camera' in the forum. 1 month ago

Hi,

I look forward for sorting QHY camera images after a session is finished. The same thing can be done with cr2 images from my Canon DSLR with gwenview, but I have problem with the QHY images. Although I can open a single QHY image with "kstars picture.fits", but all other image viewers/editors/converters do not apply the demosaic process on these images.

I look forward for suggestions:

1. Linux batch conversion method how I could generate reasonable debayered tiff or jpeg files for previewing purposes.
or
2. Where can I implement inside Indi to save a preview JPEG/TIFF or debayered version along with the native FITS.

If I understood correctly, it is not possible to run an imaging session with two cameras at the same time, right? (The Sequence Queue on the CCD tab can't run two tasks parallel.)

It is shipped with Indi and available in the PPA version and the Raspbian tar file as well.

I wrote some more information on the wiki page how it works:
