The Tulip in Hydrogen-alpha: Tulip Nebula Sh2-101 and the surrounding HII region in Cygnus, centered on the open star cluster NGC 6871. Most of this is around six or seven thousand lightyears away from us, and to give you a sense of the size of this region: that bright tulip shape is over 600 trillion kilometers wide (top to bottom in this rotation).

Images captured using the William Optics Fluorostar 132 (FLT 132) Triplet APO Refractor. Horsehead Nebula, Flame Nebula, and the Orion Nebula.
