For this image of NGC 891 I have used the data we obtained with the TEC160FL back in 2017 combined with the data obtained by AFIL-1 and 2.
The image is LRGB, despite having Alpha Hydrogen shots available I have not used them, since the result seemed very good to me.

Since the framing of the image in each of the systems varies, I had to do a lot of cropping, but I was delighted with the result.
NGC 891 is a spiral galaxy located in the constellation Andromeda, it is one of the best examples of an edge-on spiral galaxy that can be seen with amateur telescopes.

It is also considered one of the most similar galaxies to our Milky Way, the great resemblance it presents to the Milky Way seen from the Southern Hemisphere is striking, also aspects such as a similar luminosity and size, around 32 million light years separate it from the Milky Way2.

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.
