SH2-261 Lower's Nebula

Lower’s Nebula is situated in the outer regions of the Orion constellation, visually between Betelgeuse and Propus in Gemini. It mainly consists of HII ionized gas which is thought to be energised by the runaway bright star HD41997 at the centre, which is adjacent to a mysterious small bluish triangular object and a much fainter blue bubble, seen better in higher resolution images.Clear skies were unusually plentiful here at Fairvale Observatory during January, which allowed for a record of some 17-hours of integration time, albeit mostly accompanied by a waxing to full moon. The data lends itself to various processing approaches and I played around for a long while with different combinations, in the end favouring an SHO + HOO blend as the main image.

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.
