My trial on CTB1. For me one of the most fascinating and challenging targets in the sky, hence it was for me a must to target it again (see image comparison in Version C) with the new equipment. The difference is quite obvious, almost a completely new image. I have to admit though that I processed the 2 images in a completely different way, hence not quite fair this comparison.
As usual, I lack in OIII data, which I wanted to tackle with the new OIII filter, but most of you know that this so far did not go well at all. I actually added the new filter data into the numbers, they really were not helping a lot though.
I have to admit that I lead myself a bit into the artistic way of presenting this fascinating SNR, I have several other editions that might be a bit more "natural", but when I saw the result I thought: fine, it looks almost like an Andreas (Equinoxx) image, not that I dare to compare myself with him 😊. Furthermore, I hope that some of you will like it as I do, this is all what it is about!

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.
