Photo Spotlight   Image posted 11.16.2019

On November 11, 2019, the innermost planet, Mercury, transited the sun as seen from the earth. Club member Al Meloni captured Mercury in front of the sun, shown in hydrogen-alpha (H-α) light, as it approached the western limb about 12:45 pm EST. Third contact would be at 1:02:40 pm for his location at the old Merchantville, NJ, high school football field near 40N-75W. Standard contact times are measured at the edge of the photosphere, the disc of the sun visible in "white" light. It is seen here as the smooth golden limb where it transitions to the ragged-edge chromosphere. Except during a total solar eclipse, the chromosphere is visible only with H-α filtration.

Al took this photo with a cobbled-together refracting telescope, utilizing a Stellarvue tube, a Feather Touch focuser and a William Optics 80 mm FPL-53 doublet objective. It was mounted (and tracking) on an iOptron ZEQ25 equatorial mount. Image capture was through a DayStar Quark H-α filter to an Imaging Source DMK 21AU04 digital monochrome astro-camera. The AVI was processed with HandyAvi to select the best frames, then AutoStakkert 2 for the frame stack, then RegiStax for wavelets. Finally, it was touched-up and colorized with Photoshop.
