File target 4.2.15192

[Gfischer]

Hi Robin,

I just installed new version.When opening sc I first had a message stating the target for file saving doesn’t exist. I clicked on use location anyway. I then closed sc and reopened no more warning. Then to check file transfer I ran test button for target location in settings. The test starts but never completed. I just took a quick pic and it transfers no problem. I don’t write my files to computer running sc. I save files to a network computer.
No hurry on this everything runs fine. If I run the test in settings it never completes and locks up sc. thought you might want to know.

Hi George,

on startup, SharpCap tests the folder set up as the main capture directory, just to check that it exists and you can write a file to it - this gives you an early warning if there is a problem before you try to start capturing. It sounds like this check failed for you at least once, possible because the network drive that you use was briefly unavailable for some reason. Similarly, the disk speed test could take a long time if the network drive was either only available intermittently or the connection was slow for some reason.

So my guess is that this would be due to some sort of temporary network glitch - certainly nothing new in the SharpCap code in those areas for some time.

cheers,

Robin

Robin ,
Thanks for the explanation.

I have another question. I’ve been using the histogram tracking during livestacking. When using star color calibration applied once every 2 min the histogram has to be manually adjusted often. I tried applying the old white balance instead and the tracking is excellent. Am I doing something wrong when using star color calibration applied?

Thanks for any ideas you can give.

Hi,

when you say 'adjusted often', do you mean that you are regularly adjusting it between the auto calibration happening every two minutes because the drift happens between one auto calibration and the next? Or, alternatively, do you mean that the auto calibration after two minutes is not giving you the image that you want, so each time it calibrates you need to adjust?

cheers,

Robin

Robin,
At the beginning of stack I adjust after every auto color stellar correction. As the stack time increases the change of the histogram gets smaller so I don’t need to manually set histogram levels as much. When using the old white balance to color correction the tracking follows the histogram much closer. Of course the color correction is not as good as the stellar color correction.
I was thinking maybe I’ve set something wrong.

Robin,
I did some experimenting live stacking last night. I started out imaging m72 with stellar correction applied every 2 minutes. I adjusted histogram to a good view and turned on histogram tracking at 4 min. I then didn't change settings through 30 min integration. The histogram kept moving until at end view was washed out.
I then imaged a small galaxy. This time I only applied stellar color at 4 min one time only. I then set histogram tracking and didn't touch controls for the 30min integration. the view remained the dame though out integration. The histogram tracking followed well.
I think the stellar color causes the histogram tracking to lose the histogram curve due to the quick change of histogram position. The problem with not applying stellar correction is the color balance shifts. I was looking at the settings options in live stacking. If you select applying stellar correction periodically and turning on tracking the view will vary.
I saved some screen shots from last night and my log if that will be of any use.
