In this release, I delete all folders on the camera SD card...

Jasem Please avoid this nuclear option. I have files stored on the SD card that I need for Magic Lantern software mods I use to work.

Andrew created a new topic ' KStars Local Time Offset wrong.' in the forum. 4 weeks ago

I have a GPS time source with a -4 Offset in EST timezone. Everything reports correctly in INDI drivers and system clock sync, But KStars is showing only -3 offset. This is when Time & Location Updates are set to GPS & Mount Updates KStars. If I choose KStars Updates All Devices, the offsets are correct. What could be the cause of this?
There is no place to manually correct the offset that I can find while using GPS.

The USB 2 controller in the USB 2 versions of ASI cameras is not very good and has issues with Linux systems. So they recommend the USB 3 version which is still compatible with USB 2 and will perform better.

Andrew replied to the topic 'Stock Lenses and Auto Focus' in the forum. 1 month ago

Upon further experiments. I found Mirror Lockup has conflict with autofocus routine using a stock lense. Basically Live View is necessarily enabled for GPhoto to run the lense motors. With Live View on, the mirror is already up, so when a capture is triggered it attempted to take 2 pictures. This on it's own causes issues with an image stuck in the camera buffer. But furthermore it is on taking the second image when I saw the Camera's autofocus AI kickin.
After some more digging around I could avoid the autofocus AI by setting either AE lock/AF or AE.AF,no AE lock within the camera's custom functions. Great.

So the main takeaway is IF using EKOS to auto-focus a stock lense, at least on Canon, Do Not use Mirror Lockup.
Is there any way for GPhoto to know if the camera state is in LiveView mode? If that information is available to the driver, then a condition could be made not to use mirror lockup if set in that instance. This would also avoid backing up the image buffer. by accidentally forgetting to close live view before taking a picture.

I did a 'apt-get dist-update' and suddenly it works. I have no idea why but i'll take it.

I should add I was using a Canon 600D and the GPhoto driver.

I was playing around with driving the focus motors in some camera lenses and they work great, just have to be in live view to make them work. However when I attempt to use EKOS Autofocus routine, rather than a straightforward capture, the camera's Focusing AI engages and begins searching for focus on it's own. So there appears to be something different in the way Auto Focus routine is triggering the shutter.

You can configure NTP with GPSD to use the GPS dongle as a source for time without worrying about PPS. All PPS really does is keep it ticking at exactly 1 second once the time is set.
Implementation is fairly straightforward and it allows for attaching an external antenna if necessary. Basic steps include
Wiring to 5V supply
Cross wiring TX and RX to GPIO Pins on the Pi. [Tx to Rx, Rx to Tx]. Page 11 of Documentation
Configure boot/config.txt. Line 1 will enable the MiniUART , and lock to core frequency to 250, disabling turbo because Mini UART and CPU Core frequency are relative. Line 2 defines the pin connected to PPS, example here is pin 4.

enable_uart=1
dtoverlay=pps-gpio,gpiopin=4

Configure /etc/default/gpsd to collect
DEVICES="/dev/ttyS0"
as a device at startup
Finally configure NTP to use time from GPS
# Read the rough GPS time from device 127.127.28.0
# Read the accurate PPS time from device 127.127.28.1

server 127.127.28.0 minpoll 4 maxpoll 4
fudge 127.127.28.0 time1 0.535 refid GPS
server 127.127.28.1 minpoll 4 maxpoll 4 prefer
fudge 127.127.28.1 refid PPS

This is brilliant.
I highly recommend adding GPS to your project to take care of time and location automatically.

Do not attempt to draw the entire artificial horizon. That is designed to enclose smaller regions. Such as the side of a house or a tree. If you do, the shape will encapsulate the entire sky.

Andrew replied to the topic 'Any way to define a custom horizon?' in the forum. 1 month ago

So. From what I can see it is pretty straight forward.
In the horizon tab >Manage> Add Current Scope Az/Alt
Slew the scope to a multitude of points to define the custom horizon. Temporarily Disable Limit Goto to allow free control while building the horizon.
Write File to save for future
Save configuration under Options

This will prevent the mount from entering the defined area. Although I did not see it display as opaque ground in the planetarium. There may be further steps for that, but I do not know.

It is not something I have used. But from what I gather you can identify points that define the contours of a custom horizon.

Andrew replied to the topic 'Any way to define a custom horizon?' in the forum. 1 month ago

Yes. In the mount driver's Horizon tab you can add points to define your horizon by slewing to the position with obstructions and adding the position to build a horizon file. You will have to add the points sequentially.

I already had it installed. :huh:
Still no KStars Icon in the system toolbar or window bar top corner. I tried using the Oxygen theme too.
It's not really a big issue. But interestingly other icons display correctly, including the Ekos and INDI control panel's.

I got this tip from the INDI Support FAQ

You have read and write permissions to the port. In some Linux distros, this is not the default setting. Under Ubuntu, you need to add your user to the dialout group:

sudo adduser $USER dialout
Then you must restart your PC for this to take effect and try again.

I have never seen PEC training in INDI EQMOD either. I just assumed it was either never implemented or wasn't possible. It certainly would be nice if I could do that, and maybe use PecPrep with it.
My HEQ5 Pro should support it.
