FEBRUARY 2010 - PICTURE OF THE MONTH Flame and Horsehead Nebulae Image Courtesy of Steve Roche The Flame Nebula, designated as NGC 2024 (and Sh2-277) is an emission nebula in the Constellation Orion. It is about 900 to 1,500 light-years away.
Click on image for a larger version. The February 2010 Picture of the Month is from Steve Roche who took the image from his suburban backgarden at Cherrymount in Waterford, Ireland. Like many other backgarden’s, Steve also has to contend with considerable light pollution and sky glow. Steve produced the final image using a combination of 12 x 600 sec exposures taken during 2010 and 34 x 120 sec exposures taken in March 2009. All images were captured using a Canon 350D with the IR Filter removed and a Williams Optics (WO) Megrez 90. Each imaging session required manually setting up each night as Steve does not yet have a permanent imaging platform. Steve commented that combining these sessions was a major challenge!! The WO Megrez 90 Steve uses for imaging is piggybacked on a CGE11 inch SCT, which is used for guiding with an Imaging Source DMK 31AF03 AS Camera. Colour Data for the March 2009 images were captured using an Astronomik EOS CLS CCD Filter and the 2010 images with an Astronomik EOS 12nm HA Filter. Images captured with DSLR Focus, stacked with Deep SkyStacker and post processed in Adobe Photoshop. Steve is the website administrator for the Deise Astronomy Society (DAS) and more of his images can be found here
