Here is the first panel of what eventually will become a mosaic of M45.

I thought this would be easier to process than it was. Two problems:

1: Managing the star brightness while stretching the image. Does anyone have a good way to avoid blown out stars in images that have very bright stars?
2: the star in the bottom left of the image has what looks like a hexagonal diffraction pattern around it. I thought I might have introduced that somehow during processing but it is in the integration image before any processing was performed, so I'm thinking it's an artifact of my scope.

I also experimented with 180s and 240s exposures to compare Signal to Noise Ratio. It turns out that the 180s subs were better from a SNR point of view.

Anyway, here it is. I'll revisit it when I start on the next panel.

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.
