In the summer months, the area around the bright star Gamma Cygnus (Gamma Cygnus) provides a great target, even for short focal lengths. The vast hydrogen clouds there, with their sometimes turbulent structure, provide a great choice of decorations with both a telescope and a wide-angle lens. I decided to use my 135 Samyang and chose the appropriate image crop. Since hydrogen nebulae, as mentioned earlier, are mostly found in this region, a recording sequence must be made using the narrow band H-alpha filter and the RGB filters for the stars and background sky. I tracked my camera setup using the little Vixen travel tripod on my porch. While processing the data, I noticed the enormous density of stars in this area and had to reduce the density of the star layer slightly so as not to obscure the sensitive edge regions of the H-alpha cloud.
