Hoegaarden Astronomy & Photography
LBN576 is a planetary (? not decisive yet) nebula between Cepheus and Cassiopeia. It is very dim. This image was obtained after 12 hours with the Sharpstar 76MM F4,5 and the ASI2600mc. Conditions were not optimal with sqm 20 as an average. Objects as this one clearly benefit from narrow band filtering.
This is an image of “Barnard 150”, a dark cloud of dust and gas that becomes visible aginst the majestic backdrop of milky way stars and nebulosity. When you turn the image 90° CW then the shape resembles a little seahorse, turning it’s head to the right.
The image was made during two nights 7 and 8 September 2021, using the SharpStar 76mm @ F4,5 and the ASI2600mc, 201x120s or 402 minutes (about 8 hours) under a less-then-optimal sky, bad transparency and sqm 20 so Bortle class 5 or 6 sky.
