Spectroscopic Clouds





Spectroscopic Clouds

Is there any hope of penetrating these clouds by altering the spectroscopic ranges of vision?


This is the experiment to look through water vapor or clouds using spectral variances in optical light moving towards the infrared spectrum. I used the first batch of four experimental filters held in front of the iPhone camera lens and got these results. From top to bottom, a light red filter (AngelEyes W23A), H-Alpha (ZWO Ha 7nm), ProPlanet (Astronomik 742 IR), and deep sky (Optolong UHC). 

According to these results, which need to be confirmed, the red filter is the worst and actually enhances the clouds. The narrowband H-Alpha filter is the best at penetrating the clouds. The ProPlanet is second best and produces some interesting results by reversing the colors of some areas which will need additional analysis, and the deep sky filter also enhances clouds making second to the red filter. In the next series of trials, the focus will be on polarization. The study was stopped at this time because the sky quickly turned to overcast and rain.
