Tulip Nebula (Sh2-101) and surroundings

No astrodarkness here so I keep looking through my hard drives and found this OSC data of the Tulip area that I had not processed before as pure RGB without Ha data (which mainly messed it up) and I could now do it using the new XTerminator procedures. There are some striking Oiii objects in this area (as you can see here: https://www.astrobin.com/full/iurigu/0/) but I think it could be nice to just present what is there in ordinary RGB, which is quite a lot. However, down to the right (the violet object below the Tulip) you can see that the recently discovered object Strottner-Drechsler 103 (https://www.astrobin.com/5k9fxn/H/) is clearly visible also in RGB.

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.
