SH2-200

Inspired and challenged by my friend, Uwe, (see here: Sh2-200 (LBN 674, PK 138+04.1, PN HaWe 2) in HOO-RGB ( Uwe Deutermann ) - AstroBin), I attempted to give my best shot at imaging the planetary nebula, SH2-200. I found this to be the most difficult object to date for me to do (yes, even more so than the recent M76 version I posted) given it is not very bright, making processing a challenge. There are many versions of this PN posted on Astrobin and one will note the many hours required to get a fairly grainy-free image. As for the object itself, Sh2-200 was discovered in 1983 by the astronomers Herbert Hartl, Johann Dengel and Ronald Weinberger. In 1987, further narrowband observations detected a large faint outer halo extending further than the central shell. However, it wasn't confirmed to be a true genuine planetary nebula until 2017.

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.
