Sh2-101 Tulip Nebula

This will be my last image with the Agema SD 150 for a while, changing out to the RedCat to prepare for some wide field Milky Way projects. It's been a great scope for me, look forward to getting back to it in the fall, hopefully with the Agema field flattener in place of the Riccardi.

One interesting structure in the O-iii image. As presented it is south (slightly up and right as displayed) from the Tulip, appearing as a partial oval. Perhaps it is part of the Tulip, but it sure does look like a planetary nebula to me. If I push my Oiii data hard enough the oval is virtually complete. However I shoot from suburban skies and light pollution is such that I don't want to push the layer hard for presentation purposes. Perhaps those of you with darker skies can pursue this?

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.
