The Iris Nebula (NGC 7023), a bright reflection nebula set amid clouds of dark yellow-brown dust in Cepheus. The bright red star at left is T Cephei. The smaller reflection nebula at far left is vdB 14. North is up in this framing. This is a stack of 18 x 12-minute exposures with the SharpStar 94mm EDPH refractor at and with the Canon Ra at ISO 800, and through an Optolong L-Pro broadband filter. A generous application of luminosity mask curves in Photoshop generated with the Lumenzia panel brought out the faint dusty tendrils from the background sky. An application of Star XTerminator filter reduced the stars to also help accentuate the dusty clouds. Autoguided with the MGEN3 with dithering; no LENR or dark frames employed. Taken from home Nov. 2/3, 2021.
