Ok, I just tried using VNC through the ethernet connection instead. That's faster, but still lagging a little bit (but it's nothing alarming). Is there a way to get the Ubuntu server to do the following concerning network connections:

1) If ethernet is connected, WiFi signal is disabled
2) If no ethernet, then enable WiFi and look for a known WiFi (eg. my own WiFi at home) and connect to it
3) If no known WiFi is found, then use the RP as an access point.

I can't even seem to figure out how to connect the Ubuntu server to my home WiFi....

Did you configure VNC viewer to use 24 bit color and best quality? Can you share screenshot?


Yep. After yet another reboot it looks good. But it's really slow. Lag on everything (even just dragging a small text document from one window to another is lagging. My Pi is placed one or two meters away from my computer. But could it be the Raspberry Pi's WiFi signal, that's not that great?

I decided to cancel as I had a problem with the AP creation (not sure what happened). Creating the AP just froze - are you supposed to interact somehow?

I’ve started all over with the 32bit Ubuntu.

Good question. In the past, 64 bit was challenging. Keep in mind that the script does not care if it is 32 bit or 64 bit, so feel free to try and report back.
Before doing this, please check if PPAs have 64 builds of kstars and other software.

The script does care. When installing astap it downloads the 32 bit version - there is an error in the makefile concerning the g17 map file. The makefile is missing _astap in the end of the filename three times. I don’t know if there are more places it favours the 32bit Ubuntu.

Hmm, when looking at my Bias frames info in KStars and comparing to yours, all the values are pretty much the same - except Median. Yours shows 0 mine shows 526 point something in the Histogram tab but 0 in the Statistics tab. Should I be worried?

Anders Misfeldt replied to the topic 'Bias frames - No data/empty?' in the forum. 3 months ago

I don't get this!

Last night I tried turning on my RP4 with everything connected, opened KStars/Ekos and started my "calibration" profile where I only have my ZWO 294MC Pro and QHY5L-II-C cameras enabled. Then I tried a test Bias frame and that worked!? So now I have recorded 100 Bias frames (gain 120 and default gain). No errors in PixInsight anymore.

Could it have been a problem recording the Bias frames with all my gear enabled in Ekos?

I’ll test with the simulator when I get home. I’ll also try taking bias frames with my guide cam then.

I’m not home to check the version (but I’ve used the astropi3 script). I’ve so far used two or three different versions for my images since august. Some for Mac and some for the Raspberry Pi 4. They all (all bias frames from August till now) show the same “empty” files, but still with a 23.4 MB filesize.

@knro, my focal length are written in Ekos, but maybe it's not transfered to the Bias info?

Anders Misfeldt replied to the topic 'Re:Bias frames - No data/empty?' in the forum. 3 months ago

Wouter, all my Bias frames are produced in Kstars/Ekos and they show up as emtpy in all fits viewers. Values are 0 for min, max, std dev, median etc. Loading the fits files in KStars/Ekos doesn't give me a view as "Herrhausen" produces. My view is just completely white i Kstars (completely black in all other fits viewer programs) even after I've auto-stretched them. So I really don't think the problem is with PixInsight?

Anders Misfeldt replied to the topic 'Re:Bias frames - No data/empty?' in the forum. 3 months ago

No, but I don’t think that’ll help since Ekos automatically sets the bias exposure time to 3.2E-5 s, no matter what I enter as exposure time.

Anders Misfeldt replied to the topic 'Re:Bias frames - No data/empty?' in the forum. 3 months ago

Actually, Ekos selects that exposure time for me. I (by accident) sat the time to 3.725 seconds last time, but Ekos just exposed the bias frames as the lowest possible (the 0.00003 s that’s written in the header). The file was named with the 3.725 label though.
