Isn't the astroberry repo a full repo, meaning it has all of the OS, and not just the astro programs? If so, then as soon as a kernel update comes along, it'll overwrite your Banana Pi kernel with a Raspberry Pi kernel. Not to mention other differences between the two platforms.

So if you're an expert with apt, and know how to manage pinning and how to resolve conflicts between the two repositories, then sure, you can do that.

But I don't recommend it :)

Ugh, I've been looking at so many different SBCs, and so many different ODroid models, I got them mixed up in my head.

It's the ODroid M1 with an m.2 connector. As a bonus it's available with 8 GB of RAM.

I'm traveling for the next week, so it will be a while before I can test.

Yes, running make kstars does indeed work. Of course running make install fails, but that's no problem, I just copy kstars to the proper place and it works.

You can't use an SD card image meant for a Raspberry Pi on anything other than a Raspberry Pi.

To use another SBC, such as Banana Pi or ODroid, you first install the OS that they provide, then you run Rob Lancaster's AstroPi3 script which will download the source and build it for you on your SBC of choice. Pretty simple really.

Personally I'm running an ODroid N2+, with 4 CPU cores at 2.4 GHz, and 2 more CPU cores at 2 GHz, 4 GB RAM, and it even has a native m.2 SSD connector on it, although I'm using eMMC, which is still much faster than the dog slow SD cards that Raspberry Pis use. And it's cheaper than a Raspberry Pi (even if you could find one).

Yeah I have a 64GB eMMC. Plenty of room for building software :)

Just pulled the latest, still broken. :(

What a coincidence, I'm also using an ODroid (N2+ in my case).

I pulled latest git, and I am having a problem getting it to build. I even deleted my build folder and reran cmake.

It looks like you need to delete your build folder before running cmake. It appears cmake is using cached information about an older version of libraw (you probably updated your OS recently and pulled in a new libraw), that needs to be updated.

libraw changed how they store sensor temperature in recent versions of the library. The cmake script handles this, but you probably need to delete your build folder to force cmake to do the right thing.

I guess you'll just have to look in the FITS header then, which presumably you're doing anyway in order to decode the image.

I think when you receive the BLOB (the image) from INDI, one of the fields is "format". So you may have to wait until you actually receive an image before deciding what type it is.

Also, one of the standard INDI properties is CCD_CFA, which has information needed for debayering (if appropriate).
