Actually, this is 48 subs through Triad Ultra and 8 subs through HEUIB-II (RGB+Ha). Produces more natural star color.

Ain't gonna tip-toe through this Tulip.

It's the Tulip nebula (SH2-101). It's 6000 light years away in the northern sky, and 70 light years wide. It is in a busy region near the constellation Cygnus, and located in an adjoining spiral arm of our Milky Way galaxy. It's a poplular place for amateurs like me to rummage around.

The area is filled with red ionized hydrogen, as is common with nebulae, and new stars have been created in the denser areas. Quasars have been detected in the same direction. But I haven’t yet learned whether they are within the nebula or some distance behind.

True fact: The first discovered black hole was found in this nebula in 1964, confirming the theory that suggested they existed. Since then, they are easily recognized throughout our galaxy and even in others.

The nebulonic cloud has contradictory features and the usual method of following it's trail to the epicenter of the original supernova doesn't seem to work here. Clearly, the bowl shape and radiating lines suggest and explosion in the center. But the lack of chimney-like projections and absence of a tight cluster of new stars make the exact location hard to determine.

The nebula is relatively small and dim in our sky. It wasn't really noted by astronomers until 1959, and it hasn't been heavily researched since.

Tulips come in all colors and tonight I'm writing this to the jazz tune Serenade in Blue, by saxaphonist Stan Getz.

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.
