Acquisition details representative of each panel.

---

My most ambitious project at the time it was taken, over 55hrs of integration time across 4

panels. Also my first image taken completely on Solar Power!

On the plus side, I feel like I've just about got the whole "mosaic workflow" nailed down. From a specific acquisition workflow, to the processing workflow of stitching frames, I'm pretty pleased with the seamless transitions here between panels. Even knowing down to the pixel where to look, I have an extremely difficult time finding panel joins.

I'm pleased too with the consistency of color, depth, and noise across the panels. So often, while "seams" can be mitigated, one segment of a mosaic betrays itself by not blending well with the others. I feel like this image has largely avoided that.

I'm not thrilled with the stars here. I would like to do a better job of masking them during various processes, to avoid giving them some of the edges/artefacts/"processed feel" I so often produce.

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.
