Sharpcap 4.1 Timestamp anomaly

Hi, Thanks once again for a great capture program. I have just noticed a snag in v4.1 though.....the Sharpcap Timestamp (the one you see superimposed on your camera image) is one frame later than the 'internal' timestamp' (SER format). (Seems ok in v4.0) I have tried two different PCs and two differ...

Re: Digital Gain with ASI 432

Thanks Robin,

That looks to be a good solution. I like the idea of the toggle switch function for the display.
Will try this out for real on the next faint occultation (if the clouds ever part!)

Thanks again

All the best

Simon

Digital Gain with ASI 432

Hi, is there any way to access the digital gain of an ASI 432 from within Sharpcap ?
It would be very useful when using the camera for faint stellar occultations.
Other software does seem to give access to this feature.


Thanks!

Re: SharpCap Timestamp accuracy

Hi All, I have noticed a significant change! Can I summarise what the timing situation used to be, this copied from my previous post: "Firstly, when testing my usual laptop with my GPS server, I found that with an exposure time of 400ms or shorter, Sharpcap was stamping at the start of a frame,...

Re: SharpCap Timestamp accuracy

Hi, I wasn't really going to take this any further, as I am happy with how the system works (ie its reliable and accurate), but have found out a couple of bits of extra info: Firstly, when testing my usual laptop with my GPS server, I found that with an exposure time of 400ms or shorter, Sharpcap wa...

Re: SharpCap Timestamp accuracy

Thanks Robin, I agree with you....I tried the exact same trial and it does indeed stamp as expected, on longer exposures (ie the time stamp represents the end of the exposure.) I have investigated several capture programs in this way....they do vary a bit. But....the anomaly, for me, comes at 'norma...

Re: SharpCap Timestamp accuracy

Hi,

Had just one more thought on this,
Would there be any circumstances where SharpCap could allocate the timestamp of the previous frame (allocated when its exposure finished) to the new frame, just starting its exposure? (that too would fit what I'm seeing).

Thanks

And have a great 2019!

Re: SharpCap Timestamp accuracy

A small clue, possibly, as to whats happening: I find that when using a USB 2 cable, both ASI224 and ASI174 cameras produce frames that have a 'late' timecode, (very roughly 1 frame duration late). When using USB 3 (which I always do).....the timestamps appear 'correct' nearly always (ie the timesta...

Re: SharpCap Timestamp accuracy

Thanks Steve,
I'll have a look at Astro Flash timer.
