Revisiting the Helix nebula! Again, with a new scope!

First light of my new telescope - just bought a Esprit 100ED, and miracously, the clouds didn't appear!
I must say, I'm extremely satisfied with the purchase. It's a wonderful telescope, extremely well built and the image correction is perfect for APS-C sensors. Since I was installing all accessories, etc., I hadn't much time left to image. Since the helix nebula was high in the sky, it was the perfect target to troubleshoot and test my new toy!

So this is my second attempt at imaging this famous DSO. This time, however, I got around more than 1h of imaging time. NoiseXterminator was used to improve on the background noise, as 1h of imaging time is not enough to smoothen the noise. Guiding was abysmal however, and some elongation can be seen. Backfocus was not perfect either, but with the crop it's imperceptible.

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.
