My new project is CTB-1, a supernova remnant. Considering the fact that it' s 10.000 light years away in combination with the fact that it takes up a diameter of around half a degree on our night sky (similar to the moon), lets me say "What a blast!!!". This explosion is 100 light years in size.

George Abell catalogued it as a planetary nebula, Abell 85, but it later became aparent that it's indeed a supernova remnant.

Rumors say, that a pulsar was created within the supernova and was ejected from the bubble at a 1000 km/s causing the rupture in the bubble that gives it it's descriptive name "The Popped Balloon Nebula"

Imaging this object turned out to be extremely challenging. There is so little light to capture. It will take me a longer time to complete this project. After 7.5h of capturing H-Alpha only, the basic shape slowly becomes visible.

Oh dear, what have I gotten myself into with this one?

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.
