I have to say that I am using Astroberry very successfully, these days on a RPi4, but doing polar alignment quickly and within a few tens of seconds of arc using my guide-scope and camera combination. Last autumn I was happily doing polar alignment with my primary scope and my Canon DSLR before I bought the guide-scope. I don’t have a permanent fixed set up and so have to carry out an eyeball alignment and levelling of the mount each evening (and my mount doesn’t have a Polarscope and I don’t own a Polemaster). Using iPhone compasses or old-school analogue ones is really not particularly accurate when you’re carrying your tripod and mount, perhaps like my case loaded with your scopes. Don’t forget you’ve got to allow for magnetic deviation in your locality ( See: www.ngdc.noaa.gov/geomag/data/mag_maps/pdf/D_map_mf_2020.pdf )
So these days I use my finderscope to make sure Polaris is somewhere in sight, and then when it’s getting darker trying a first polar alignment. I would be disappointed if the PA routine measures my pointing error at more than half a degree.
However the thing I do use my iPhone for is setting the RPi clock time. I struggled with a GPS dongle, initially clashing with VirtualGPS and subsequently taking so long to locate sufficient satellites for a good fix. I found it was much easier to use my iPhone and particularly the App ScopeTool to give me precise location and time and also show me where Polaris is with reference to the north celestial pole at that moment. So when I turn on the power, I log into the RPi from my laptop using VNC Viewer, open a console terminal window in Raspbian OS and set the precise date and time by the command sudo date -s '15 Jun 2020 15:30:00'. If I can’t remember the details of this command, I just modify the old command from my last session, found in my terminal command history by the up arrow cursor key.
Then when I open KStars/Ekos/Indi it wakes up in the correct time, and if necessary I add the location geographical coordinates spelled out from ScopeTool.

Yes - you can boot directly from ‘any’ USB storage device. My Astroberry implementation now resides on a Sandisk Extreme SSD which is super fast. I have also tried out a 1TB 2.5” hard drive in an IcyBox USB3 carrier. It works pretty well although RPi agnostics tests gives an overall FAIL due to random read /write speed being a little below the test threshold score.

Progress !
So I now have Astroberry 2.0.1 running on my RPi4 directly from a Sandisk Extreme SSD. I followed a couple of videos on Youtube ( youtu.be/zVhYvvrGhMU and youtu.be/AskGItLhESk ). Once I had Raspbian Buster running from the SSD with no microSD card, then using Balena Etcher, I burned the Astroberry 2.0.1 image to my SSD. I copied into the boot partition the 14 .elf and .dat files which are on the GitHub repository (as described in the second YouTube video, and as I had already found successful with the plain Raspbian) . So Astroberry now boots at lightening speed from the SSD. Only one small problem yet to solve - I need to expand the file system to occupy the whole of the SSD. At present I have access only to around 8GB of the much larger SSD. I tried using raspi-config Menu item 7 Advanced Options Menu item A1 Expand Filesystem but get the message "sda2 is not an SD card. Don't know how to expand".
I guess I need to seek some help from the experts on the RPi forum!

When eventually, after various steps of attempting to get it to carry on working, I went to turn off the power the screen showed an animated rotating image saying Recording...Remaining Images :1. Since then I have tried various cures including changing power supply from mains adapter to battery and back, updating the camera firmware to the latest version, and changing SD cards, even though the images are not normally saved to the SD card.

Has anyone encountered this before, and any good ideas for solving the issue?

One final 'cure' remains for me to test, to attempt to drain down the internal power source which maintains the date and time and camera optional settings. I have removed the main battery, but I haven't a clue how long I will need to leave it to drain down, or if this may be any help at all! By the way, the camera seems to function quite normally when used in standard camera modes (P, AV, T, Auto etc) with shortish exposure times up to half a minute.

I am using the Astroberry Server 2.0 on my Raspberry Pi 4 4GB, and have carried out a sudo apt update && sudo apt upgrade, but otherwise not looked deeper at which Indi driver I am presently using.


Not sure why this problem suddenly occurred after six months and more than a thousand image captures (mostly Darks and test exposures!), however it seems to have been cured by going deep into the ‘custom’ settings menu on the camera and disabling all of the features that are not needed when imaging, especially long exposure noise reduction.

It seems that the RPi foundation has issued a beta version of the USB bootloader (which does not require a microSD card in addition). I presume I could install Astroberry onto my USB SSD after setting the SSD up as the (only) boot device. But is there a way of using the Astroberry 2.0.1 image file directly?

Have you tried installing it by hand?

Not yet - my software experience is limited - I would need my ‘hand’ holding by someone more expert.....

Radek,
I have been following some work on building a live stacking function to run on a Raspberry Pi 4 (see als-app.org/index.html ).
In the latest communication from the authors, they have developed a software package to run on the RPi4 under Raspbian. Although in an early stage version, could this be added to Astroberry? (see post #8 in this thread www.cloudynights.com/topic/683836-als-astro-live-stacker-v06/ )
