Large Image files with these new cameras

[yomamma]

I was wondering if the >50 megabyte image files produced by the new cameras are going to create issues with timing related to processes that might need a quick turnaround, such as a focus routine.

On my ASI294MC Pro I can run a 3 second focus exposure at 300 gain and get good results. The file size is only a little larger than 20 megabytes and the data transfer is fast and not noticed,

On my ASI2600MC Pro I noticed that it takes about 5 seconds for the image transfer to complete as the file size is larger than 50 megabytes.
I have had some fails on image retrieval from this camera during the use of autofocus and I was wondering if I should have a minimum of a 5 second exposure so as not to create any issues with backlog and its handling.

My most recent sequence got stuck in autofocus when it continually failed on image retrieval and maybe this would help.

Thanks for any suggestions.

You could do as it once was ....
use the ROI to select only a few stars for focus

Hi,

are you running over USB2? I would only expect a noticeable delay for image download on USB2 - on USB3 it should be pretty much instant, certainly considerably less than one second. I don't have the ZWO 2600, but have the equivalent camera from a couple of other manufacturers and the download time is ~0.2s or so.

cheers,

Robin
