This is my version of NGC 3521, a very cool looking spiral galaxy in Leo. I decided to go after this object like I choose most of my objects and that is searching Stellarium. It is a decent size which was important since I was using the AT115 refractor rather than the Edge800. It is 35 million light-years away and 50,000 light-years across. It is quite colorful with pink star-forming regions as well as blue clusters. I was very surprised with the flocculent nature surrounding the core as well as some of the other finer structures in the arms. The other unusual feature of NGC 3521 is that it sits inside fainter bubble-like shells. These shells are believed to be tidal debris from satellite galaxies that have merged with NGC 3521 long ago.

I did crop this image to get a closer view but not too far as I really like the colorful starfield. The better shaped stars are the benefit of the refractor over the SCT but of course you lose out in focal length. Several small galaxies can be spied on in the background as well which is another reason for not cropping too much.

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.
