Jurgen, the SDK which is on the github has some issues, in my testing 55% of 20x 10s frames are very very short exposures. Today I got the newest SDK from Yang (the developer of the SDK) where this issue is repaired. We are both testing since some hours and no issue so far. He will upload the new SDK if his testing also is without problem. If you like you can try it yourself, I attached the SDK. You have to rename the libASICamera2.a to libASICamera2.bin to build the driver.

Jurgen, just did some in-depth testing with flats and even with the new SDK there is something wrong from 1 to 1.7 sec. I reported that to Yang.

Just recompiled indi_asi_ccd with your latest SDK you've provided, I see the same behaviour.
I've just ended my first astrophotography session using INDI Library + EKOS and captured ngc6888 + m27 with unguided exposures of 30 seconds.

With same behavior do you mean the 1-1.6s bug or that ~50% of the exposures are "bias"?
Anyway, two days ago I successfully run a scheduled session on M27. Start after twilight, align, autofocus, guiding and several 300s exposures until halt at dawn everything fully automated by EKOS and it worked flawless! :woohoo: :woohoo: :woohoo:

Great! Are you using the stock INDI ZWO driver or you used updated SDK from ZWO?

I'm using the SDK I posted above, as I said there is still this bug between 1s and 1.6s. And it is only working with 45% bandwidth limit and USB 2.0. But aside of this it seems to work. According to Yang the problem comes from the libusb they are using.

I mean with same behavior the 1-1.6s bug, I have no problems with losing half of my exposures. I used the SDK provided in the message right above with the latest hithub driver, and the 45% bandwidth limit and USB 2.0 settings I didn't change.

Yes the SDK I posted only fixes the problem of losing half of the exposures. The 1-1.6s bug is still there and Yang is working on it.

Hi Guys,
How did you test the ASI1600? I could not make mine work with indi. It works like a charm with linguider though it is not a guiding camera :)
I tryed with the indi ppa but it did not work. then I got the latest sources from SVN and built the latest ASI driver to no avail. Any help is welcome.

In this post indilib.org/forum/ccds-dslrs/1326-zwo-as...d.html?start=24#8959 you can find the newest SDK (not officially released). Then you need to rename one file from .a to .bin and build the driver yourself. Very important: It does only work with USB2.0 and you should set the bandwidth to 45. The only known remaining bug is that exposures from 1s to 1.7s are broken otherwise the driver works fine and I already run two sessions. Yang the driver developer from ZWO is working on the issue.

This is strange. I am linguider developer and I created the linguider driver tested the camera with linguider. it works just fine with all settings of bandwidth... never tied usb3,0... This is quite strange...

Is there a repo for linguider or is it closed source? Otherwise can you look at Jasems driver perhaps you can spot some issues in the code?
