Double Trouble Cluster

Before you "like" this picture, list of failures:

1. Unprecise focus

2. Slight tilt in the train, T2 ring sits loosely

3. No pollution filter used (tunnel effect, removed with Fitswork)

4. Poor sky condition, high clouds

5. Guide star lost multiple times as clouds crossed

6. No prior sensor cleaning

An excellent example showing what can go wrong, among others...

By the way, I tried "Hasta La Vista Green" PS plugin for the first time. Highly recommended. There are no green men in space, indeed.

Description: Hello Friends,
So sorry, by intending to wrap the image description with a sheet of humor I have left the impression as if I am utterly disappointed with my work. Actually, the "list of failures" contains minor issues only and I have indeed produced way worse pictures before. You are all too kind, like a family I'd like to hug, but I recommend you won't let me do that. The sky is an open heart. Thank you all so much, stay safe and healthy!
Cheers
Robert

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.
