NGC 4565, The Needle Galaxy

A popular target for amateur astronomers. Relatively nearby spiral galaxy viewed almost exactly edge-on, similar to NGC 891. Probably a barred spiral type. The colors transition to distinctly blue at the outer edges, suggesting recent star formation in the arms. There is a large cluster of galaxies in the far distance near the upper right edge of NGC 4565.

Captured with a monochrome camera and L,R,G,B filters. Got L exposures over two nights mid April, with good seeing. Capturing R,G,B exposures was delayed two weeks by full moon, cloudy weather and windy conditions, in succession. Finally got R,G,B exposures over three nights at the end of April and beginning of May, with a mixture of good and poor seeing.

Was hoping to get more L exposures, but never got the chance. Nevertheless, very happy with this result. Especially the sharply resolved "cloud decks", color variation, and other fine details visible across the disk.

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.
