Elephant's Trunk Nebula ( IC 1396)

I am usually aiming at something rarely, or even never, imaged, which gives me a thrill (and sometimes a dissapointment) but this was the last night of the season since astrodarkness is just about to disappear up here, and most nebulae are now behind my northern obsy wall, so I played it safe and aimed at something bright and striking, and therefore often imaged.

Fortunately my dual-RASA rig doubles the length of the night. However, processing it was interesting since I found it hard to find any thrustworthy reference image to glean at. This seems to be the nebula where everyone goes ad libitum and over the top when it comes to colours, whatever filters used.

Well, here is my version of it. Ha and Oiii, with the quite broad bandwidths of the lovely IDAS NBZ filter.

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.
