The 50mm f/1.4 continues to perform fairly well, though its still difficult to get perfect focus since bright star in live view may look decent enough, yet show triangular corner stars when viewing on a larger monitor the next day, so don't zoom in too much on this one. Anywaym the color data was taken under BOrtle 1 skies with decent Transparency. Once I returned home I found my crappy apartment balcony (Bortle 7) still had some northern visibility between the trees, so I spent several clear nights at home shooting a few hours of data using the Hα filter. That data still looked like trash overall, but it was good enough to allow combination into the color image to boost nebula contrast

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.
