This picture shows the well-know classic object of the Dumbell nebula, or M27. I could image this object for more then 10 hours on several clear nights lately, with 8 hours of H-Alpha narrowband (7nm) and 2 hours of RGB.
The planet barely clears the houses and tress. This is madness. Red spot showing nicely however. All images with a 180mm Maksutov & ASI290MM. Some artefacts I did not remove. I did not use an ADC (Atmospheric Dispersion Corrector)
