My annual trip to B33 resulted in quite a pleasing image with my portable rig. Four hours integration shows off this dark horse against glorious curtains of Ha emissions excited by Alnitak. There is a price for using an OSC and dual band filter - halos! Perhaps I pushed the colour saturation too much, so I've posted a revision with more gentle processing in Nebulosity using levels and curves.

B

Title: Processed in Nebulosity

Description: Simple stretches and curves bring out the detail without saturating the colour.

G

Title: A stereo 3D version

Description: If you like a challenge - relax your eyes and move the image close to your eyes until you see 3 images, them move it slowly out, concentrate on the middle image, allowing your eyes to cross 👀, until it pops into focus - you'll get a nice 3D effect. PS don’t stare too long or you’ll get a headache 🤕.

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.
