Dr 29
Astronomy Now Picture of the Month December 2021
Featured in the Deep Sky Newsletter of the British Astronomical Association 3 January 2022
A new discovery by my dear friend Marcel Drechsler of a probable planetary nebula in Aquila. Although Marcel first detected this in May 2019 it is only now that it has been fully imaged. Drechsler 29 is large (16 arc minutes) but very faint, especially in OIII - hence the long integration time.
As a bonus we also have the smaller (27 arc seconds) known planetary nebula IPHASX J193308.9+15535 (PNG 051.7-01.7) at the top of the image. This is the first time this has been imaged in colour.
My sincere thanks to Marcel for so expertly processing this image for me.
