VdB 142 in Hydrogen Alpha Light

Van den Bergh 142 is an interesting area of bright and dark nebulosity in the constellation of Cepheus.   The long horizontal structure in the center of the image is VdB 142.  It is also known as the “Elephant’s Trunk” and as IC 1396A.  VdB 142 is part of a much larger bright and dark nebula complex with the designation of IC 1396.  Only a small portion of IC 1396 – the bright background and the dark nebula filaments throughout the frame – is seen in this image.  IC 1396 and VdB 142 are about 2,400 light years from Earth.

This image was taken on two nights from my light polluted back yard in Vista, San Diego County, California with the Stellarvue SVQ100 telescope and a ZWO ASI1600MM-C camera.  The image is a combination of 97 x 270 second images and was taken with the ZWO ASI1600MM_Cooled camera set to a gain of 200 with an offset of 50.  I used a Baader 7 nm bandpass 36mm unmounted hydrogen alpha filter.  The individual subexposures were calibrated, aligned and stacked with PixInsight.  A light application of MultiscaleLinearTransform was used to attenuate noise.  A light stretch was performed with HistogramTransformation.  Final contrast adjustments were performed in Photoshop.
