I did choose the defaults and when I logged in I noticed that as opposed to other installs I've done in the past, there was nothing on the desk top. I am curious about setting up an auto-start of the ekos server so I can connect to it with the client on my Windows PC. Maybe you have it already auto start transparently? I haven't looked. I have it installed on my RP4 but haven't connected anything to it yet. Maybe tomorrow.


Most likely you logged into Gnome. Gnome out of the box has an unusual interface. In any case, for some reason, Gnome is burning a lot of CPU so not recommended.

In the login screen, you need to pick KDE Plasma. KDE is a more conventional desktop system and works very well with Ekos/Kstars.

You have to start Ekos manually from the menu.

I updated the instructions with a link for the download page.

Micheal,
Good suggestion, I will implement this next time I touch the script.
Did you run into any issues?

Florian,
I saw this feature in the nightly.
Problem is that I don't have a temperature sensor and also I don't know how effective it would be - my understanding is that different components come to temperature equilibrium at different speeds.
My suggested feature should solve the problem without any additional hardware.
I might just implement this feature myself, but if anyone wants to do it, please post here.

Alex Varakin created a new topic ' Progressive "Refocus every" in EKOS' in the forum. 3 weeks ago

My 10" RC has a habit of losing focus very quickly at the beginning of the session.
I guess it is caused by a quick cooldown by the fans.
One way to solve this would be to set up "Refocus every" at a very short interval, but the problem is that once the telescope is thermally stable, refocusing would be taking time without good reason.
So suggestion is to have progressive "Refocus every", where the following parameters can be setup:
1. Initial duration - how long to wait till 1st refocus (default 10 min)
2. Progressive factor - a multiplying factor, which will be used for calculating next refocus period (default x2)
3. Maximum duration - no longer increase duration, after this value reached (default 120 min)

Port 9998 has worked for quite a while.

As far as the focuser, I haven't implmented it yet. I did get into the habit of using 1 micron = 1 step in Config.h. I'd like to not break it for anyone potentially using it, but I need to refresh myself on the focuser. I'll probably let it toggle.

Couple of things on my todo list (numbered for convenience, not priority):

1. Changing the MaxRate replacement (degrees per sec)
Question on this: Would people prefer a settable 50-200%, as Degrees per sec, or the 50,75, 100, 150, 200%?
2. Intervolometer support
(Might be a priority, simply because I have some D5100s, and if I could trigger them as well as the main one in Ekos, that'd be handy until the Ekos/Kstars Imaging train gets done.)
3. Focuser Changes
4. Dew heater
5. Weather support. (Read BME280/etc)
6. Tangent arm support (Plate solve then adjust?)
7. Check backlash values (Changed to allowed to 3600)
8. DC Focuser support (Not sure if that works already or not?) Might need someone who has one to help with this.
9. TMC_SPI reporting support. (I got one for testing, and finally went to put it in on this cloudy night. I unfortunately missed the: You have to have both axis be SPI if one is, so this will be working at some point, but when is a big question. Oops.)
10. Equivalent of MoveAxis support to allow for following satellites. (Kstars issue more likely than OnStep directly, as the custom rates are added in, but Kstars doesn't have a way to send the rates/information, AFAIK)

Anything anyone else wants?


James,

A few months ago, when I was working on getting PEC running, I noticed that the import and export of PEC training data are not working. The buttons are there, but they don't do anything.

I have set up two RPi4 using this script and everything is running great so far.
The only issue I ran into was with gnome desktop - for some reason, it is burning a lot of CPU.
For some reason, Kstars/EKOS has issues with managing windows under all desktop environments, except KDE, where it does not show window management buttons for EKOS window and also windows do not behave as independent windows.
I switched to KDE desktop and it runs much better and window management functions work properly.
The script has been updated to install KDE instead of Gnome.

I have done some testing and so far everything seems to be working.
I have no idea why, but 20.04 seems to be much faster than 19.10.

Hi All,
I updated my AstroPiMaker4 script and instructions for building astroimaging system using RPI4 and Ubuntu 20.04.

Here are the features of the script:

  • Installs most commonly used Astrophotography software: INDI, Kstars, PHD2,CCDCiel,Skychart, Astrometry with sextractor, ASTAP plate solver
  • Sets up Wireless Access Point
  • Sets up x11vnc to be started automatically with headless operation
  • Defaults to Gnome Desktop, but KDE and Mate can also be installed

More details and script itself are available under:
github.com/avarakin/AstroPiMaker4

Feel free to use and fork.
