This necessitated the cancellation of an astrophotography trip I had planned to the desert. Instead, I setup the equipment in my backyard and shot an image of M42 through narrowband Hydrogen Alpha, Oxygen III and Sulfur II filters. One of the advantages of these filters is that they’re much less affected by light pollution and moonlight than broadband filters. I selected M42 because it’s my daughter’s favorite object and thought she might appreciate seeing it take shape as she recovered. Additionally, I hadn’t seen an image of M42 shot in what is known as the Hubble Palette. I was very pleased with the result.” This image was acquired using an Explore Scientific ED127 f/7.5 refractor telescope, an SBIG ST-8300M camera and a total of 19 hours of exposure time. Faworski captured this wonderful image of the wispy NGC 6995 that lies in the Cygnus constellation. The nebula is a small part of the Veil Nebula, which is a vast and complex supernova remnant that is divided into three main parts – the Eastern Veil, the Western Veil and Pickering’s Triangle. The image was taken using an Explore Scientific ED127 f/7.5 refractor telescope, a QSI 583wsg camera, a Baader filter and a Paramount 1100S robotic telescope mount. VdB 152 This image by Faworski showcases the reflection nebula VdB 152, which lies atop the trailing Barnard 175 Bok Globule in the Cepheus constellation. The image was taken using an Explore Scientific 208mm f/3.9 Newtonian telescope, a QSI 583wsg camera, a Baader filter and a Paramount 1100S robotic telescope mount. The Rosette Nebula “I wanted to attempt a very high resolution mosaic image with my Explore Scientific ED152 so I took on the very large field of the Rosette Nebula. The final image is composed of 100 hours of exposure time in a 4 panel mosaic. It captures the entire nebula at better than 1 arc second of resolution.” 32 Sky’s Up Sky’s Up 33
