Galaxy Pair NGC 4145, 4151

Hello everyone,
It's been exactly 2 months since my last recording. Unfortunately, there wasn't a single gap in the clouds in between that could have been used.
But now, 2 clear nights in a row and that with a new moon.
Jackpot!🤩
Since many nebulae are difficult or impossible to reach, I decided to start the galaxy season.
First up is the pretty pair of galaxies NGC 4145/4151 in the constellation Hounds.
NGC 4145 is a Hubble-type barred spiral galaxy SBcd.
It is estimated to be 47 million light-years from the Milky Way.
The galaxy shows little star formation except at its outer edges. Due to the loss of energy that occurs without star formation, some astronomers predict that the galaxy will degenerate into a lenticular galaxy in the near future. However, the galaxy’s interaction with NGC 4151 “could sustain its star formation.
The object was discovered on March 18, 1787 by Wilhelm Herschel.
NGC 4151, also called "Eye of Sauron", is a barred spiral galaxy with an active Hubble-type SBab nucleus.
It is also estimated to be 46 million light-years from the Milky Way and has a diameter of about 85,000 light-years.
At the center of the galaxy is a supermassive black hole that emits X-rays.
The exact origin of this radiation has not yet been clarified.
Together with NGC 4156 and PGC 38756 it forms the galaxy trio Holm 345.
Hope you like my start to the galaxy season. It is clear that there are more clear nights this spring than in recent years.

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.
