M45 Pleiades at f/2

When I was trying to shoot the Orion Nebula for my daughter, I had to wait several hours for it to clear the trees in my yard. So, I pointed the scope at the Pleiades just to see whether I could capture any of the dusty nebulosity around the perimeter any better at f/1.9 rather than at my last attempt with the RedCat51 at f/4.9. If the rule of thumb of (f-ratio 1/f-ratio 2)^2 holds true, this current attempt at 2.5 hours of integration is the same as trying to capture nearly 17 hours of data with the RedCat. All this with a OSC camera as opposed to monochrome on the RedCat shooting LRGB.

Pretty awesome physics, and I was definitely able to get more dust captured than I was even having the RedCat51 out for 13 hours the last time! Hope you enjoy!

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.
