Tulip nebula (Sh2-101) in SHO

The Tulip nebula is another nice objects to get experience with narrowband and SHO at large focal length. Main problem is that nebula emission extends much further than the size of the image, so a reasonable background extraction is difficult - on the next occasion I need to get some wider field image so to do multiscale background extraction. So take the corners with a grain of salt. Regarding the color composition, I find a combination of 50-70% pf foraxx's dynamic narrowband combination (www.thecoldestnights.com) with 30-50% straight SHO to give quite nice results without the need to too radically eradicate green.

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.
