Messier 27 (M27), a.k.a The Dumbbell Nebula, captured from my backyard on 09/01/2023. M27 is a Planetary Nebula located in the constellation Vulpecula. It is fairly easy to observe visually in either binoculars or telescope. Use of Nebula filter (like a UHC or Oiii) can improve contrast, making the nebula "pop" in the eyepiece. This image was captured with a dual narrowband filter between my telescope and One Shot color Camera (OSC). This type of filter only allows specific wavelengths of light (Hydrogen-Alpha and Oiii) and is perfect for emission nebulae (Planetary Nebulae are subset of Emission Nebulae). The image was captured a couple of days past Full Moon, which would have been far more challenging (maybe impossible) without use of the filter.
