I imaged this target earlier in the year from the southern hemisphere with a FSQ106N and an older CCD KAF8300 sensor (https://www.astrobin.com/r4rdfu/). This time around, I was able to image this target from the New Mexico desert with my Epsilon 160 and QHY600 camera. I am a bit biased but I think the Epsilon produces better images with the QHY600 compared to the FSQ and the KAF8300 CCD (although I think the FSQ would produce some amazing images with the newer CMOS sensor). The Oiii signal was definitely cleaner and much easier to bring out detail with the faster focal ratio of the Epsilon 160.

I have also become a little bit biased towards the diffraction spikes with the Epsilon. When I first started imaging with a refractor, I always thought the diffraction spikes were a bit of a distraction. Now that I have been imaging with a newtonian, I have really liked how they turn out.

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.
