IC 1396 Elephant Trunk Nebula HOO

A one shot colour version of the Elephant Trunk Nebula taken using an Esprit 100ED telescope, ASI2600MC camera and the Optolong L-Ultimate filter.

This was edited in two ways to get natural stars and a Hubble style palette. One edit was calibrated with SCC to get the correct colours of the stars and then again with the Narrow Band Color mapping script in PixInsight to produce the deeper blues of the Oiii signal and golden hues for the Ha signal. The stars from the natural edit were extracted and added to the Hubble style edit.

Prior to editing, the image was drizzled x 2 to help make the very small stars appear round rather than small squares. I am happy with both experiments and will use the same technique for more OSC narrow band targets this summer.

Taken over three bright Moon nights June 2024 at Los Coloraos Observatory, Gorafe, Spain in dome 1.

Thank you for looking!

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.
