Details:
Mercury and the Pleiades were 1.1 degrees apart tonight shortly before setting. This image was acquired in fading light and dust haze in Tucson about 5 degrees above the horizon. This is an 830 nm cutoff infrared image comprised of a stack of 16 x 1 sec. The stacked image was doubled in size and adjusted with Photoshop. The older 180 mm Nikon F2.8 is quite good for imaging in IR. Mercury is quite bright in IR as are the hot stars of the Pleiades making the imaging easier and the sky glow of the twilight is somewhat suppressed increasing the contrast. This approach worked quite well to extract the conjunction from the twilight haze of Tucson AZ.
The backyard scene source image is shown is single image.
