I think I've fixed it; I flashed the ASI120MM via Windows with the standard .icc and all works fine again. I tried the compatible.icc but still had the problem. Hopefully after a few hours guiding I'll have my confidence back. Thanks for suggestion, will save in case I need it at a future date.

May be worth a try for others;

During the setting up of my imaging gear on an HP laptop running a newly installed Ubuntu 18.04 I had an issue with my ASI120MM (USB2) guide camera not taking images; it was getting stuck in an 'expose' loop everytime I went to take an image, the exposure time just kept looping with no image taken (FWIW; the odd 1 out of at least 50 tries did come down). Tried all the usual hardware and setup changes but to no avail. However, in the process of trying everything, I asked for LiveView and hey presto it sprung back into life. Now it happily takes frames as demanded.

Fingers and toes crossed all is well from now on.

I only had this happen once therefore offer this as a suggestion only. My solution was to start a throw away 600sec luminance exposure and then start the cooling half way through (with the unticked 'Enforce') as the exposure was active. Once the exposure was finished I ticked the Enforce box and started my keeper sequence. What was your starting temperature? Mine was around 20 degrees c cooling to -10.

Just a thought; as an interim feature, could it be possible to select an overlay (akin to cross hairs and guidelines) and centre a Bahtinov mask directly on the selected star in the acquisition images. The selected star will still be auto focused as usual but the viewer will see the Bahtinov mask pattern results as the focus becomes more accurate. We are talking about a pretty bright star for Bahtinov therefore the pattern can be proportionate to the corresponding HFR .

Note: should this be an existing feature on other applications I was truly not aware. I only use Ekos.

Interesting. My Luminous flats were successfully taken at 0.011 sec with basically indoor ambient light. When below that time the image generated included horizontal lines.

Just a quick suggestion; don't have your light source too bright. Keep it nice and low and the exposures will be long enough for the camera to adjust to the desired ADU.

I too had a similar issue but since updating to nightly build and updating as mentioned in this post all is ok.

Keith Cobby replied to the topic 'ASI Camera - Gain/Offset/x-Bit' in the forum. 10 months ago

For guiding I think the camera settings all come down to matching a gain with the guide image interval. 1 sec is probably a good choice. I use the ASI 120 for guiding on a little 50mm f4 guide scope and keep it at its Unity setting. If you're struggling then maybe Bin the capture image and or create a master dark for subtraction.
For focusing with the ASI 071, as Jasem mentioned earlier in the thread, avoid saturating/saturated stars. At F6.25 you shouldn't have too many focus problems. The odd super bright one won't be selected for focusing so pay attention to the median brightest stars as focus candidates. The auto process works very nicely. You can always check with a Bahtinov mask as a confidence booster.
