Shot taken with 400mm telescope at Dr.Remeis observatory in Bamberg. Unfortunately bad seeing that day ( about 4'')
Used a 11Megapixel CCD-Sensor with cooling option (-20°C for these shots) to reduce dark-current.
Picture consists of 4 exposures:
- 1 clear filter 200s exposure
- 1 H_alpha_line filter 300s exposure for red channel
- 1 OIII-line filter 300s exposure for green chennel
- 1 SII-line-filter 300s exposure for blue channel.
M27 is a deep sky object. Distance: 417pc, visual magnitude: 7.5mag

Great Shot! Lots of detail for only about 20 min exposure. Well done
