Tulip Nebula - Sh2-101

Taken on a summer trip to the Outer Banks with relatively dark (but humid) skies. The mount power cable may have gotten snagged after the meridian flip losing half of the data I could've obtained...

but at least it's still working fine and I've resolved the issue that caused the snag.

A bit of tiling weirdness that's visible in the starless one but the stars pretty much hide it. Not sure but I think it may have been caused by GraXpert. Overall did a good job of removing the gradient though so kept it

Title: First Processing

Description: This was my first pass at processing this data when I just got PixInsight. I like that a bit more dust is visible on the left but I think it's stretched a bit too far and has more noise than I'd like so definitely like the new version better overall personally. I think the background extraction on this one also took out a bit too much of the very faint dust towards the right side

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.
