Summary

Description
العربية: NGC 6960، أو سديم الحجاب، هو سحابة من الغاز والغبار المُسخَّنين والمؤيَّنين تقع في كوكبة الدجاجة. وتشير تحليلات الانبعاثات الصادرة عن السديم إلى وجود عناصر الأكسجين والكبريت والهيدروجين. ويُعدّ هذا السديم أيضًا أحد أكبر وأسطع المعالم في سماء الأشعة السينية. ويمثّل الحجاب الغربي للسديم (المعروف أيضًا باسم كالدويل 34)، ويتكوّن من NGC 6960، المعروف بأسماء مثل «مكنسة الساحرة» أو «إصبع الله» أو «السديم الخيطي»، ويقع بالقرب من النجم الأمامي 52 الدجاجة (52 Cygni).وتفاصيل صورة NGC 6960 هي عبارة عن فسيفساء مكوّنة من ثلاثة إطارات، التُقطت باستخدام خمسة مرشِّحات مختلفة: مرشِّحات الأحمر والأخضر والأزرق القياسية، مع تعزيز التفاصيل ببيانات الحزمة الضيّقة للهيدروجين (Hα) والأكسجين (OIII). وقد جرى تمثيل لون الهيدروجين (Hα) بالأحمر، ولون الأكسجين (OIII) باللون الأزرق المخضر. وعليه، فهي صورة ملوّنة تمثيلية نتجت عن زمن تعريض إجمالي يزيد على 39 ساعة.
English: NGC 6960 or the Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. The analysis of the emissions from the nebula indicate the presence of oxygen, sulfur, and hydrogen. This is also one of the largest, brightest features in the x-ray sky. It is the Western Veil of the nebula (also known as Caldwell 34), consisting of NGC 6960 (the "Witch's Broom", "Finger of God", or "Filamentary Nebula") near the foreground star 52 Cygni. The image details of NGC6960 is a three frame mosaic taken with 5 different filters, standard Red – Green – Blue with details enhanced with narrowband data of Hydrogen (Ha) and Oxygen (OIII). The Ha was color mapped to Red and the OIII to teal. So it is a representative color image consisting of over 39 hours of exposure time.
