Mouseover of M51 The Whirlpool Galaxy and surrounding galaxies- First light with new primary mirror!

The Whirpool Galaxy is a spiral galaxy in the constellation Canes Venatici. It is 32 million light-years away and 109,000 ly in diameter.

First light of a new custom Ottiche Zen primary mirror in the 130 PDS OTA. Thanks to Roman Zen, Venice, Italy for making this! Very pleased with its performance.The original mirror cracked when the mount and OTA were blown over in the high winds we had earlier this year!

With the original image, I decided to tone down the processing on this one. Trying for a more subtle ´natural´ shade of blue and detail in the in the galaxies without blowing out the core. I then got sucked into the AP desire for a bright blue galaxy with enhancement of the Ha emission spots. Tried SPCC, this seemed to do the trick. But image still needs some more work and/or more data!

Original: Complete field of view - no cropping at all. There is something about a wide field image of galaxies that gives me a feel for the enormity of space and the distances between our planet and the rest of the universe.

Revision D: Crop with mouseover from the wide field image.

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.
