Helix Nebula (NGC7293) in HHO

A very famous planetary nebula which looks like a big eye laying in the dark sky. This version enhances the faint Ha signals of the matters that spilled out from a white dwarf laying on the very center. Around the center one could also see some interesting columnar-like structures sharped by strong stellar wind.

Data were acquired using the Chilescope T2 and provided by the Youth Astronomy Society of peking university (PKU YAS). The processing of this image was done by me with a total integration of 4.5 hours, 2 of Ha and 2.5 of OIII. With a 0.5m telescope much details are revealed but it seems like a disaster at the background of this image because the integration on the image was too little to have a smooth background while preserving the faint signals. I had tried many noise reduction processes but the results were bad. Perhaps given more data it would be better.

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.
