Thanks a lot for the fix. With the weather here, there is plenty of time for it to migrate into the stable kstars :-)

I look forward to trying the new algorithm and will report back how it works, when the weather permits.

Soren created a new topic ' Focus module bug in ekos/kstars 3.3.9' in the forum. 2 weeks ago

Hi!

I wanted to try out the latest "linear" focusing algorithm and updated kstars to 3.3.9 (RPI 3, Ubuntu, kstars build: 2020-01-02T08:28:54Z). I can not any more move my focuser inwards any more and get a focuser error. This happens both when pressing the "inwards" button and using autofocus (tried all 3 algorithms). Outwards focusing works fine. The inwards button also seem to work for a few clicks when just starting everything up, but then the error comes and it does not work anymore. This is the message in the log:

[2020-01-04T19:29:02.225 CET DEBG ][ org.kde.kstars.indi] - FCUSB1 Focuser : "Error: Invalid range for FOCUS_TIMER_VALUE. Valid range is from 0 to 5000. Requested value is -1000 "

I came from a pre-linear-focusing version where it never gave an error, so maybe this new change introduced the bug?

Hopefully it can be fixed easily :-)

Best Regards,
Søren

Unfortunately I can't help you, but I do feel your frustrations. Have had the same kind of problem with my qhy2pro. Now I got a custom driver from qhy that works, but I dare not update indi until I get another RPI set up since there is no turning back to an old version with apt. I think it should be prioritized to allow install of all old versions of Indi, not just the latest, since updates sometimes break stuff.

Rant over, I do love Indi so thanks a lot for all the hard work :-)

Is your system time correct? Type date in a console and check.

Soren created a new topic ' HFR values' in the forum. 4 weeks ago

Hi!

I think my focusing is not too good, judging from the FWHM values in my long exposure images, which is about 4-5". I use a 10" Newton with a ccd yielding 1.3 "/pixel. The guide module report about 1" corrections.

When focusing I can get down to about 1.75-2 HFR in ekos autofocus. Is this good enough/to be expected? What values do you guys get for sharp focus?

The optimal focus position also seems really flat, so I am suspecting that something is off in my system, but where to look is the question....

My script looks like this

#!/usr/bin/python3
import json
import subprocess
from datetime import datetime
encoding = 'utf-8'

now=datetime.utcnow().strftime("%Y-%m-%dT%H:%M:%S%z")
res = subprocess.check_output(["/home/pi/isItClear.sh"])
clear=int(float(res.decode(encoding))>0.75)

if clear==0:
    msg="Cloudy"
elif clear==1:
    msg="Sky is clear"
else:
    msg="Something odd is going on..."
    clear=0

print(json.dumps({"timestamp_utc": now,"roof_status": {"open_ok": clear,"reasons": msg}}))

The 'isItClear.sh' script just read a file on another RPI, which has an all sky camera attached to it and determines if it is clear by counting the number of stars it catches.

Nothing have been thoroughly tested, so use at your own risk ;-)

You really saved my day! Everything is working as it should now after correcting the "snooping" settings everywhere. WOW! Can't thank you enough :-)

I don't know why you want to do this, but I do something similar for weather safety using this

indilib.org/devices/weather/weather-safety-proxy.html

and a simple script that reads a flag from another RPI using ssh.

Soren replied to the topic 'FITS header coordinates wrong - why?' in the forum. 4 weeks ago

Nice catch, I found this in my FITS header
TELESCOP= 'Telescope Simulator'

Maybe that will solve my plate solving and mount issues!

Thanks a lot :-)

Soren replied to the topic 'Is ASTAP ready for seamless integration in EKOS?' in the forum. 4 weeks ago

Would it be possible to put the ASTAP and database packages into indi/kstars's already existing ppa for even easier install with apt?

Is ASTAP using the header information written by ekos in a temporary fits file? I.e. if this info is wrong, ASTAP will fail to solve?

Soren created a new topic ' FITS header coordinates wrong - why?' in the forum. 4 weeks ago

Hi!

I did some testing last night, since I still can't seem to get indi/kstars/ekos working. I unparked the scope, did a goto, a plate solve + sync and another goto to end up at M33, which the mount did. I then captured a couple of images and decided to try ASTAP as the clouds had rolled in. So I loaded one image into ASTAP and tried to plate solve but it could not find the field. Then I noticed that the FITS header had completely wrong RA and DEC of M33 in the files I just captured. I deleted the lines with coordinates and tried to solve with ASTAP and it worked fine, when I set the coordinates manually to a star close to M33.

Here is some info from the image:
Focal distance ........... 1049.82 mm
Pixel size ............... 6.45 um
Field of view ............ 30' 24.9" x 22' 10.6"
Image center ............. RA: 12 17 19.085 Dec: +16 40 39.44
Image bounds:
top-left .............. RA: 12 16 10.727 Dec: +16 49 57.25
top-right ............. RA: 12 18 17.041 Dec: +16 53 22.60
bottom-left ........... RA: 12 16 21.257 Dec: +16 27 55.27
bottom-right .......... RA: 12 18 27.332 Dec: +16 31 20.22

What can be the reason for these wrong coordinates in the FITS files I captured? The mount seemed to hit M33 pretty OK after just one plate solve/sync.

Best Regards,
Søren

Hi!

I use vnc to a RPI 3 running Indi+kstars/ekos and think it works great! If you think the RPI 4 is too slow to run kstars/ekos, you could just switch it with something more powerful, say an old laptop or desktop with Ubuntu.
