Never planned on making this a mosaic really, hence the different exposure settings for each pane. After a couple stretches in PS it became apparent that the difference in ISO, f ratio and over all exposure time were going to make it quite tough to process so i ended up being a bit careless and not putting as much effort in as i perhaps should of! But it will do until i can make a fresh start on a similar image, perhaps including M78 off to the left.

Exposure for left:

50* 180 seconds, f3.2, ISO 800, calibration frames, 200mm

Exposure for right:

29* 120 second exposures, f2.8, ISO 1600, calibration frames, 200mm

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.
Dismissals 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.
