Planetary Mode - Some Questions


rac

Question

Having used BYE a few times for Planetary imaging, I have some questions that I have not been able to find the answers to in the help system.

1. Is there a way to save settings such as the nnumber of frames to capture and file type? I generally use 2,000 and AVI respectively but these settings revert to 100 and JGP/AVI on start up.

2. What is the delay,  afiter capture, with some sort of memory count down about? Is it the transfer of cached frames to file? The time spent in this phase can but short but can also be quite lengthy.

3. Last night I noticed that capture time became slower and slower and eventually found that there was dew on the coorector plate making the image progressively dimmer. Does BYE adapt to changing brightness during image capture to acieve the requested "exposure"? Alternatively does this happen in the calculation phase at the beginning of capture?

4. I get the impression that the simulated live view "exposure" is brighter than captured in the AVI and/or JPG files and that I need to check captured images for exposure.

5. Sometimes the number of frames is less than the 2000 requested (sometime a lot lees). Does BYE drop bad frames and, if so, are there threshold settings to control this?

Overall I am getting good results from BYE and I am happy with it.

1) No, not at the moment :(

2) Planetary recording is done in-memory to capture as much frames as possible as fast as possible... if you have a slow hard drive you will get left over images that have not to been saved once the recording is complete.  If you start a second recoding before the first one is done saving images this will slow things down.  To prevent this as much as possible go to advance settings and use the background server and use processor affinity.  This may make a difference as the foreground process and background process will run on 2 separate cpu core with no cross-threading.

3) I think this is due to #2.  Dimmer images will not slow anything down, it is irrelevant.

4) What you see on screen is what is saved, as-is with no alteration.

5) Yes, some frames may get dropped, but not by BYE, by the camera.  Every once in a while the SDK won't send an image.

Regards,

Thanks for the replies. Item 1. Your answers clear up a lot of the finer details for me,

Item 1 would be nice to have. It's just a matter of developing a routine I know, but I regularly forget (with everything else that is usually going on) to change these settings to what I want them to be.

Any perceived brightness issue could be because I am outside in the dark when using live view I suppose.
