QRSS Image Averaging

First test on 10min QRSS spectra averaging using http://tawbaware.com/imgstack.htm
Thanks to NH7SR, it seem somewhat obvious how to record timed spectra. With good stability and timing assume, image registration seems not to be required. Hence, simple stacking or averaging would be a promising start. Here's some first stuff, not refined yet... a somewhat early pre-alpha stage.


Raw Data

The following 6 images are raw spectra, as recorded and used for the averaging.

Averaging Result

Conclusion

The settings are pretty much same used for the online grabber. For an averaging grabber, more noise, i.e. contrast & brightness, could be tolerated. Data acquisition with more aggressive settings is presently ongoing.
I believe, the first hour, compressed into 10 minutes show a promising start and some potential when the learning curve is surpassed.


Update

Some more spectra are in, as promised, more aggressively set. This is what those look like.
