I don't have this camera or really know anything about it, but I would guess that the webcam driver would be your best bet.

It looks like the touptek commit 2367f2d5c29dd33961bfcd9479391a35cc4a9377 deleted the support that I added for OEM cameras, which included the Meade Touptek cameras. I'll can try and add it back in since I just updated my astro computer and also see that there's no driver present for my Meade LPI-G cameras.

Jasem, the Meade Touptek driver uses the Touptek library but has some special code to make the Meade cameras work with the library. It would be really nice if the official Touptek driver would just support all of the rebranded cameras, but I don't expect Touptek would be willing to do that.

I've checked my Meade LPI-GM Advanced (Touptek imx178 rebadge) and see a maximum value of 16k, which matches what you're seeing except that I'm using a 14-bit sensor. I see the same thing with my 14-bit Canon T7.

It seems to me that what you're seeing is normal, or at least, not a problem. I stack with siril so unfortunately don't know if pixinsight needs additional configuration to handle this. It is odd that you don't see this with the ASCOM drivers, though.

Thanks,
Ben

I don't have this camera, so can't reproduce your issue but is there an option to select 12-bit mode? Even with the data only using the lowest 12 bits of the 16 bit space, I'm surprised that this couldn't just be stretched.

The driver is available in the standard indi release, so you shouldn't have to build it. I'm using Jasem's PPA and can install it by doing "apt-get install indi-orion-ssg3".

Debayering the images in kfitsviewer is not supported since the CCD for the DSI Color (ICX254AK) uses a complementary color filter array rather than the "standard" RGGB CFA. The CMYG CFA was used on some of these older cameras but is not really used anymore.

I don't have pixinsight, but a little searching seems to indicate that it can debayer these images.

I pushed another branch called bin_no_deinterlace. This has the same changes as the other branch and an additional change to not deinterlace the frame if y-binning is enabled. I think this will work better, but I it would be nice if you could test both and find out for sure.

I think the file should be at /usr/lib/udev/rules.d/99-orionssg3.rules. Do you still see this problem after rebooting?
