Caldwell 101 a first test from the backyard

After weeks of no sky, very bad weather, I got 3 small windows that allow me to get 3 captures of this object, the galaxy Caldwell 101. I did a fast stretch of it, just to see a few details.

C_101 is a very interesting galaxy, according to Wikipedia and other sources it is a galaxy which should be really similar to the Via Lactea or Milky Way, also with non regular companions as the Magellan clouds.

For a galaxy, it is quite close, only 25 millions ly, and there are a few very nice images of it, like this one taken with a large scope from Australia, https://astrodrudis.com/ngc-6744-caldwell-101/, or this one from ESO, La Silla observatory https://astrophotolab.com/spacefolder/?show=g11-18eo.html

Still I will be collecting more data to go to the limit of my ED80, and see how can be improved another bit, plus a better processing of it.

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.
