With a diameter of (only) 1.4 arcminutes, Strottner Drechsler 11 is not one of the giants among planetary nebulae and the PN is also anything but sparkling in terms of surface brightness, as it took almost 100 hours of exposure time to image this shy jewel in the constellation Cygnus. Strottner Drechsler 11 was confirmed as a true planetary nebula by the Frenchman Lionel Mulato in 2020 through a spectrum. The structure of the nebula can be described as classic, so StDr 11 consists of a thin H-alpha layer with a bubble of [OIII] in the centre. The central star of the PN is so faint that it can only be recognized from high-resolution survey images. Coordinates: 20:20:50.30 +29:49:51.10

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
