Abell 85 - The Popped Balloon Nebula

This has been one of my longest and difficult projects to date. Really neat target, I love how the Oiii intertwines with the Ha.

Processing this one was… difficult.

Processing this one was… difficult. I used WBPP to stack all my nights together. Once I had my final pics, I StarAligned to Ha, DynamicCropped, ABE, BlurXTerminator and StarXTerminator’d the Ha and OIII. I then used GHS to stretch them to where I wanted ( I think there’s more potential possibly….). I then used pixel math to combine my ha and oiii. I then did a bit of Curve transforming to muck around with the colours. For the OIII I hit the image with an SCNR and then used the OIII mono image as a mask to really brighten up the colour.

Moving onto the stars, I also ABE’d star aligned to ha and dynamic cropped these. Then I used star exterminator to really bring out the stars VS whatever was int he back (INTERESTINGLY I found I actually had some of this SNR’s signal in my luminance and red channel at 90s shots… wild). I then GHS stretched one to apply to all, combined them then finally combined with the starless image to get the final. I then used PS’s camera raw filter to muck around with the finer details.

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.
