The Internal Structures in IC405

In my earlier pictures of IC 405 I could never really get good OIII data. I knew there was OIII data near the centre but didn't have a good idea of where relative to the Ha.

After searching for good pictures on Astrobin I found this awesome example by Gary Lopez:

I wanted to try to capture the 'blue wall' in SHO as well, as a test of my Baader OIII filter while maintaining the wispy Ha and SII details. The blue OIII seems to be 'below' the Ha and SII details in the end result.

I knew I had to get at least 10 hours in each channel again, and pepper the results with RGB stars.

Anyway, this is my shot at IC405. I hope you like it!

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.
