With the 16 megabit cameras the image files are very large and strain the USB connections to download in a timely manner. This is especially true if the computer has USB 2.0 connection or if a USB hub or active extension cable is used. Employing an internal buffer in the camera will help avoid image loss. At least one of your competitors offers this feature in their APS-C chip cameras.

Hi Tim
all ASI Cameras have internal memory buffer
just the buffer is not big enough to store one image

but no image will lose as the image buffer can store some lines of one image
and sensor will wait these lines transferred and start one new transfer later
so there is Handshake protocol to keep data safe

the advantage have a larger buffer is you can read out one image into buffer in very fast speed to avoid amp-glow issue, that's why 071 has amp-glow when connect USB2.0 and nearly no amp-glow when connect USB3.0

anyway we will add such feature in our future products

Thank you Sam. I'm buying a new computer with USB 3 ports and a faster CPU. I found that my CPU is running a full speed when capturing and saving camera images while stacking images in AstroToaster. Hopefully the new laptop will resolve this issue.
