Tulip Nebula Sh2-101 in Cygnus with OSC Hubble Palette

The Tulip Nebula (Sharpless 101) is an emission nebula located in Cygnus constellation that lies at an approximate distance of 6,000 light years from Earth.

It has an apparent magnitude of 9.0 has a linear diameter of about 70 light years. The HII region is called the Tulip Nebula because its shape resembles the form of a tulip and it has a reddish glow in long exposure photographs. Astronomer Stewart Sharpless listed the object as Sh2-101 in his 1959 catalogue of nebulae.

This is the Tulip processed with a Hubble-like palette with a OSC camera.

Of interest is the image was taken likely with an incorrect back focus that resulted in elongated stars in the four corners. The image has been severely cropped. Since this image was taken I have purchased a TeleVue corrector.

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.
