NGC4565 Needle Galaxy

The Needle has been on my short list and it seemed like a good couple of nights to try the C9.25HD at f/7 on it, although the 120sec subs at gain 240 washed out the saturation of the bright blue stars more than I anticipated. I'll have to return for imaging those better.

Nevertheless it's a keeper! I've retained a slightly wider field to show more of the other background galaxies nearby.

I like the curvy star trails and smaller galaxies in this view.

This was my first try of Topaz Labs Denoise AI. It did a really good job of pulling out details of the dust lanes in the Needle, so much so that I became skeptical that it was possibly "inventing" details unfaithful to reality. So before posting this image I took a look at other Astrobin images (and an APOD image) from larger (~14+") aperture 'scopes to validate that indeed it did a faithful sharpening, at least to my eyes.

For those interested, I discovered that Denoise AI works better on the original camera sensor resolution and not as well on a 2x drizzle stack. The best workflow was to use the drizzle stack for most post processing then downsample it before running Denoise AI.

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.
