Slow image acquisition, unusable files since upgrade to W10

guntram

Dear forum,

I do not know if this has been discussed before. A search did not yield meaningful results, so:

A couple of weeks ago, our club obtained a new Lenovo laptop, running Win 10 to replace the ageing HP Win7 machine we have used since 2009.

I installed the latest version of FireCapture (64 bit), and the latest native drivers from the ASI website.

My ASI 224 took advantage of the USB 3 connectivity, and performed magnificently.

My ASI 120MM, however, hovered around 3 FPS, and produced distorted AVI files that were useless. Now and then, distorted, cropped images of Mars would appear.

I changed the USB traffic settings, ROI sizes. No effect.

Trying out the various USB ports made no difference either.

Image acquisition went without a hitch minutes later with the same cable and the venerable HP laptop running FC 2.5.

Has anyone on this list encountered similar problems? Any help is appreciated.

Thanks,

Guntram Lampert

Try this, set the bandwidth to 40, Highspeed mode = on.

You know the 120mm is a very old design type, is not much compatible with morden laptop models.

Hi, Sean.

Thank you for your reply.

I tried out your recommendations, but, unfortunately, no improvement.

It looks as if I have to use the outdated HP laptop to use the 120, which is still a good camera, to good advantage.

Clear and tranquil skies,

Thank you for update, it's hard to find out, did you try another USB cable? And how long is it?
