Re: ASI178MM 14 bit?

Thanks Chad,

That explains the difference I see.

Re: ASI178MM 14 bit?

NO. this is not the question. I know it is stretched to 16 bit by shifting. My point is that it shifts 3 bits instead of 2.
(but on bias frames the shift seems correct)

ASI178MM 14 bit?

Hi, always used this cam for planetary/solar but started to use it for a some deep-sky (don't have a cooled cam yet ...) Although mentioned as a 14 bit cam, the max value i can see in the FITS files is 65528. This looks like the 14bit value is shifted by 3 bits instead of the 2 bits I expected. (and...

Re: Time Out errors with ASI-178MM /Linux SDK

Hi Chad, Yes I checked, but for some reason when setting it up from grub it will not go over 200. Tried setting manually, but no idea if that really set the value higher. (You never know in Linux). You are right it can be a battle to make things work. Looks like I will have to use my W10 license for...

Re: Time Out errors with ASI-178MM /Linux SDK

Hello Chad, an update: tested again, now on my ASTRO machine. Changed there also the usbfs memory and run firecapture again. There is some improvement but still lots of errors, even without recording to disc. In 8 bit mode seems to be better (even when recording, only a few errors) In 16 bit when re...

Re: Time Out errors with ASI-178MM /Linux SDK

Hello Chad. Did run the command and the output was 16 :? Then i remembered seeing a note on the FLir pages about default 2 MB by default assigned in Linux to image capturing. So i changed this in Grub: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.usbfs_memory_mb=1000" updated grub and rebooted. ...

Re: Time Out errors with ASI-178MM /Linux SDK

Sorry for the confusion. Of course I meant SuperSpeed (it was a busy day yesterday) See: log [10886.178171] usb 4-1: new SuperSpeed USB device number 3 using xhci_hcd [10886.199165] usb 4-1: New USB device found, idVendor=03c3, idProduct=178c [10886.199169] usb 4-1: New USB device strings: Mfr=1, Pr...

Re: Time Out errors with ASI-178MM /Linux SDK

Thanks Chad. That is exactly what I see but then on my USB 3.0 ports (land shows up as high-speed device, so that looks ok) If I did the calculations right (not that good in these) the data stream would be just over 3Gb/sec in 16 bit (correct me if I am wrong) so still plenty of speed left on 5Gb us...

Re: Time Out errors with ASI-178MM /Linux SDK

sorry chad but i cannot accept that answer as valid. If I run on the SAME hardware once with W10 and then with Linux (real machine, not VM) and one OS runs without problems and the other OS not, than there is nothing wrong with power supplies. I have tested this on 3 different machines: I7 laptop (W...

Time Out errors with ASI-178MM /Linux SDK

Hi, testing again on Linux now with the ASI178MM camera. That cam is giving me a lot of problems. Used oaCapture, Planetary Imager and now the first Linux version of FireCapture. Tested on several machines, different USB ports and different cables. All (Linux) software suffers from severe time-outs....
