Markarian Chain of the 25th of April -160 120 secs unguided subs

Acquisition type: Lucky imaging

While the main scope (Orion 250 F 3.9) was imagine the "eyes" galaxies in the Virgo cluster (ngc4438 and ngc 4435), the secondary scope (TS65 Flat) put on top of the Orion was imaging the same starfield. But as for the focal differnce and for the size of the camera sensor (Nikon d5300 agains QHY183) the TS65 was able to image the full Markarian Chain of galaxies.

It's a large and famous galaxies group in the Virgo constellation.

Stacking with DSS, processing with PS and artificial flat with Astroflat pro plugin.

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.
