M16 Eagle Nebula

Eagle Nebula is probably the most known deep space object, due to one picture from the Hubble Space Telescope. The pillars of creation were detected, where the new stars are born. I already captured this nebula by using narrowband filters and a monochrome camera. This time I used a different approach – one-shot color camera + new IDAS NB1 Nebula Filter. This filter should completely suppress the light pollution from sodium lamps and partially from LED lamps, passing the most interesting wavelength of H-alpha, OIII, and H-beta. In my opinion, it works well even in my light-polluted home.

M5 Globular Cluster

Messier 5 is a globular cluster located in the constellation Serpens. I revisited this cluster after four years. Such a spectacular deep space object simply deserves more attention, than I was able to spend four years ago. At that time I used the same telescope, but now I have a different coma corrector and camera. Moreover, this time I dedicated significantly longer integration time, specifically I was collecting the photons 2.7 hours, which were traveling to us 24 500 years.
