The Helix Nebula

Before imaging the Soul nebula on 10-28-22, I tried my luck getting some shots of the Helix. This was hit and miss since in my area of the world the Helix is relatively low in the horizon. Thus, when I was hoping to shoot it, the trees were blocking this nebula. So, I waited and waited and finally it emerged from behind the tree limbs, and I got in some shots in before the Helix vanished among the trees again. I was only able to get about 12 usable shots and I used a Takahashi FSQ-130ED refractor operating at a focal length of 650mm. My imaging camera was a Canon Ra. I did use a light pollution filter and a custom white balance. Dark frames were taken and they did help and I used a library of Bias frames. No flat frames were used. My ISO was 1600 and the image duration was 300 seconds. The image you see was cropped from the field of view of my camera sensor. I used a 200mm focal length guide scope and a ZWO guide camera. I used PHD2 software for the guiding and also APT software. I did use dithering between images.

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.
