Sh2-101 The Tulip Nebula OSC with L-eXtreme

The Tulip Nebula spans approximately 70 light-years across, and lies at an estimated distance of around 6,000 light-years from Earth. At the heart of this nebula is a young and massive star known as HD 227018, which serves as the primary source of illumination and ionization for the surrounding gas clouds which emit light mainly in the characteristic red hues of hydrogen-alpha (Hα).

Subframes taken on the night of June 15, 18 and 19, 2023.

This target was one of my first completed with the Optolong L-eXtreme dual band filter. While the local strong light pollution was effectively removed, the OIII region in the central "tulip head" was difficult to bring forth. So just a twinge of purple came through, due to a originally weaker signal at the OIII frequency. The last time around I used a mono cam with much more OIII integration versus hydrogen filter exposure to get more color contrast. Nonetheless, I was fairly satisfied with details yielded by this OSC and filter combination.

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.
