From Denebola to Vindemiatrix

This is a mix of nine sessions taken with the omegon minitrack for seven of them and the brand new Star adventurer for the last two, which let me discover what WALKING NOISE is (what a curse !). However I managed to hide it, but need to dither.

When I first started astrophotography one year ago I took the exact same photo with a fixed mount and 50 x 8s exposures, 56000 ISO. The result was a black and white set of blurry spots that I guessed (for some) being galaxies. I had to take my revenge , and althought I have distorted stars on the borders and strange color artefacts on some stars, I'm very happy with all those tiny galaxies spread all over the field.

Virgo cluster contains 1300 galaxies and is 50 millions light years away.

Around 40 galaxies are visible on this image and the faintest stars around magnitude 15. I used drizzle x3 so the file is quite big. Feel free to zoom in...

Enjoy.

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.
