Pelican nebula - Sep2022
Pelican nebula (IC 5070) is located in Cygnus constellation, right next to the North American nebula. This emission nebula is about 1800 light years away and is 30 light years across. In this image I was struck by the incredible detail that can be seen in the silhouetted dark dust regions.
Really happy with how well the current setup is working. For auto guiding, the RMS error is consistently less than 1 arc second. This makes nice round pin-point stars even with 5 minute long exposures. The narrowband L-eXtreme filter performs very well with light suppression.
