Sh2-101 Tulip Nebula

This is an object that I had on my target list for a long time and finally this year I planned to spend the whole summer on it and thus achieve a good amount of data. Unfortunately this year the weather has been very uncooperative and between troughs, dust from the Sahara, tropical waves, hurricane threats, I barely achieved 8.45 hours of integration. Still I decided to give it a try. Processing it presented quite some challenges as the Sahara dust layer that has prevailed this summer degraded many of the frames considerably and I had to work with them as is. Despite all the setbacks I am happy with the result I achieved. Thanks for watching!

Description: The original version had some traces of chromatic noise that I was finally able to remove with a careful application of TGV Denoise on on the chrominance channel. I hope you can also notice the improvement.

Description: Dialing down the noise with Russell Croman's NoiseXterminator. I also changed the color profile to Adobe RGB. Now I am much more happier with the overall result in spite of the short integration time.

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.
