A testament to the Samyang - Cloudy Orion Mosaic

The sky looked fairly clear when I setup but when the first sub came in it was obvious that some faint cloud was continually moving through. Undeterred I carried on as I still wanted to see what a quick 4 panel mosaic of Orion would look like. I need on optimising the position angle of the camera, but the image here is just 30 x 30s (15 minutes) per panel. In hindsight, the L-eNhance would have brought out loads more of the Ha especially in the upper part of the image showing Barnard's Loop.

I thought this was still worth uploading if only to show the Samyang's capabilities at F2 in such a short space of time and in less than ideal conditions.

Have a glance at the revision image which gives a glimpse into the sub quality and cloud!

Captured with Voyager, stacked & calibrated in APP and lightly processed in PixInsight - mainly just trying to remove the cloud, nothing else.

Mosaic was created by integrating each frame in APP, taking into PixInsight for DBE then back into APP to stitch it all together.

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.
