Tumbling object near NGC7008

When photographing planetary nebula NGC7008, one of pictures showed a tumbling object. As the time was 60s, tumbling time is less then 30s.

Planetary Nebula NGC6894

Planetary Nebula NGC 6894 is located in constellation Cygnus and about 5443ly away from Earth. It was not my intention to observe this nebula as I was searching for another planetary nebula. I must have used a different number... by luck it was also a planetary nebula. On the picture is also a double star NGC6896 and open star cluster IC1315. 

Setting : Nikon D7500 and TLAPO80/480 f/6, ISO3200, lights 16x60s, darks 5x60s. Camera was controlled via software DigiCamControl. Stacking of nef files using APP and final editing and cropping with CS4.

Planetary Nebula NGC7008 or Fetus Nebula

NGC 7008 (Fetus Nebula) is a planetary Nebula located in constellation Cygnus and about 2800ly away from Earth. In the middle of the nebula we can observe the central star (mag 13). According database Simbad two stars, very close to each other and each mag 13 are in the middle of the nebula. It is not clear to me of both or only one is part of NGC 7008.

Setting : Nikon D7500 and TLAPO 80/480 f/6; ISO3200, lights 16x60, darks 5x60. Stacking of raw (nef) data using APP and final editing and cropping with CS4 (tiff to Jpg).
