The planetary nebula Abell 70 (PK 038-25.1) in the constellation Aquila on August 24 / 25, 2019 and on August 26 / 27, 2019. Abell 70 is 13500-17500 light-years from earth, is approaching earth at 79 kilometers per second and expanding 38 kilometers per second. The galaxy PMN J2033-0656 is shining through the cloud of gas of Abell 70, giving it a diamond ring effect. Abell 70 was discovered by George Abell in 1955 (source: Wikipedia).

Fourty-three 3 minute exposures at ISO 800 were added for this shot with the DeepSkyStacker software (resulting in a 2 hour and 9 minute exposure) and the final image processing was done in Photoshop.
Equipment: Canon EOS 450D Baader modified camera, TeleVue Paracorr Type II coma corrector, 16" f/4.5 "Ninja" dobsonian telescope riding on a dual-axis Tom Osypowski equatorial platform, Lacerta MGEN autoguider, Lacerta off axis system (field of view comparison: image of the moon with the same equipment).
Elon Musk sends his kindest regards! During the two hour exposure time at least 32 Starlink satellites crossed the 24 x 36 arc minutes field of view featuring Abell 70. The satellites are part of the first batch of 60 satellites that were launched in May 2019. Approximately 12,000 satellites will be deployed within the next few years.
