M88 wide field

Wide field because this guy is too distant for my 102GT. I do like the interesting neighborhood though! NGC 4523 is a Magellanic spiral galaxy located about 35 to 50MLYs. NGC 3476 is ~450MLYs, (go ahead and pixel peep on this one...amazing from a small refractor.)

M88 is 50 to 60MLYs and more than interesting on its own - from Wikipedia: "M88 is classified as a type 2 Seyfert galaxy, which means it produces narrow spectral line emission from highly ionized gas in the nucleus. In the core region there is a central condensation with a 230 parsec diameter, which has two concentration peaks. This condensation is being fed by inflow from the spiral arms. The supermassive black hole at the core of this galaxy has 107.9 solar masses, or about 80 million solar masses." and "Seyfert galaxies are one of the two largest groups of active galaxies, along with quasars. They have quasar-like nuclei with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, their host galaxies are clearly detectable."

Had to throw out many subs due to bright satellites. I could really use more RGB data but the moon is now too close. I do have some Ha subs but not a help (at least with my skills).

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.
