Abell 74 is a large, Ancient Planetary Nebula in Vulpecula with a distance of 2500 LY from Earth. The Progenitor Star is the tiny blue star just above and to the left of the large central star. Click on image to magnify and bring it into view.

Astrophotographers BEWARE! This one is extremely faint!

My first attempt on Abell 74 with 5-minute subs was futile. After viewing the first 2 subs that came in, no Nebulosity showed up, only stars. I thought maybe the plate solving was off or a Stellarium error, so I cancelled the target and proceeded to my backup.

After doing more research, I concluded that longer subs were needed. So, this time I attempted
8-minute subs. Finally, it was showing up! There is some Oxygen in the central core and I had to stretch it out to resolve it from the limited O3 data in my stacked image. 20x600" subs for each filter would have been ideal.

Thanks, Eddie

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.
