Hello Friends,

again I was going for a rarely imaged object: Sh2-71

Probably of its size, it is out of reach for smaller setups. There are only around a dozen images of Sh2-71 on AB. But I wonder, why it is not imaged more often by the larger setups, since it is outstanding nice.

SH2-71 is a very structured and complex Planetary Nebula emitting strongly in Ha. The complex structure can be seen in Ha only. Therefore I have added the Ha-stack too. Unfortunately it is not so obvious and noticeable in the final composite, though I used the Ha stack as lum-layer. Processing was tricky and I have discarded many approaches, but I have learned a lot again.

I hope you enjoy this unusal and rare object

Please enjoy!
Rüdiger

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.
