Lead Time acquisition
Posted: Fri Aug 18, 2023 2:37 pm
Hello,
I use genika software since several years to do star occultations by astéroides and I have start to do some tests to pass to sharpcap.
I have difficulties to found a configuration that work well because of variation of the acquisition lead time.
To measure this lead time I register the blinking of a pps led and the issue is that I can have 1 or 2 time exposure of lags and the consequence is that the acquisition lead time change with time exposure.
With genika I don't have this issue, I have a lead time of only few ms and is it constant when I change time exposure.
I guess that this lag is due to to use of the buffer camera but I'm not sure.
Is there a way with Sharpcap to be sure to don't use the camera buffer?
An other thing I have found is that there is a lag of 1 exposure time between .ser or .Fits, for example if I have a lag of 2 exposure time with ser, I have only 1 exposure time with Fits.
For information I use ZWO1600 and 533, I have join an example of configuration I use.
