Re: ASICAP released

Just a quick note to say thank you for this app! It works perfectly on the Nexus 5X. I had so much fun doing IR photography with the ASI290MM. This makes the AsiCams even more useful! Great job!

Re: ZWO ASI120MC / RAW16 Long Exposure / Linux

With the ASI1600 there is a threshold in the exposure, above which only one bulk transfer is used instead of many rolling ones. I would suggest to set the environment variable LIBUSB_DEBUG to a high value before starting you program to check what is going on.

Re: ZWO ASI120MC / RAW16 Long Exposure / Linux

The fact that it works for Windows is a data point I missed (I have only Linux boxes at home), thanks. I will give another look this weekend if I have time. BTW here: https://github.com/chripell/yaaca/blob/master/hacking/asill.c is a driver that directly handles the ASI120MM/MC without using the pro...

Re: ZWO ASI120MC / RAW16 Long Exposure / Linux

Sorry for the negativity, but I've never made it to work decently. I think simply there is not enough bandwidth with the small size of transfers in compatible mode (one can argue why bulk transfers are used instead of isochronous ones but this could be a long story). I use the old ASI120MM in 8bit m...

Re: ASI120MM on Linux (my report on RPi3/INDI)

Thanks chripell... that's pretty advanced stuff for me. If I understood correctly, you're currently ok with the compatible firmware, bandwidth set to a low, fixed value, and 8 bits per pixel. Exactly as you said, but on an i7 laptop. I use the ASI120MM together with an ASI1600MC. The ASI1200MM is s...

Re: Tips on sensor cleaning? 1600mm-cool

Disclaimer: this is not an advice, you can easily scratch your sensor, so you are on your own. It only describes what I did understanding all the possible consequences. This said, after some dew (or ice then melted at room temperature as I may guess from reading another thread about the ASI-071) tha...

Re: ASI120MM on Linux (my report on RPi3/INDI)

Ah, I see. With the compatible firmware I've never ever got a good frame in 16 bit even on a i7 laptop :-( I use the old ASI Camera for guiding so 8 bit is OK and it works. I think the limitation about maxPacketSize is because of BadUSB attacks. Here is a patch to work around it (but then, I decided...

Re: ASI120MM on Linux (my report on RPi3/INDI)

Have you tried to adjust USB bandwidth to something fixed instead of auto? I found it critical for smoothly running the ASI1600 under Linux (even on a beefy laptop) together with the ASI120.

Re: Dark current vs temperature graph for ASI290MM

Sorry for coming back to this, but finally I had time to look at the graph to decide cooled/uncooled. It is pretty surprising there is a factor 10x difference for the ASI290 (it has 10x more noise) at -20C while it is roughly the same at 20C, compared to the ASI1600. I was thinking that that the phy...

Re: Version Check on ASI224MC-Cool & ASI290MM-Cool

Just a quick confirmation: v1.3 as the latest PCB refers to ASI290MM (both cooled and uncooled) as well? Thanks!
