NGC 3628 - Hamburger galaxy

Revision title: Siril and Gimp edit

Link: https://www.asztrofoto.hu/galeria_image/1645692861

I recently had the opportunity to buy a Skywatcher HEQ-5 Pro Goto mount. Obviously I had to test it

I like this galaxy a lot, and I thought it would be an easy target. Later I was proven wrong

Anyway, being the first light with the mount I'm happy with the results. I had a hard time to properly polar align the mount, hence I only could shoot 50s long exposures.

I don't know why I have those vertical stripes. Any suggestions how to remove them either during recording or post processing is welcomed!

I temporarly shared all light and dark files (I had no flats as the ASI 120 has such a small sensor it looks directly at the center of the FOV. so I don't need to compensate much for the vignetting).

Title: Siril and Gimp edit

Description: I've played some more with my image in Siril as I was really not happy with the vertical banding.
To use Siril, it helps a lot not to randomly click on the texts and buttons but to read a tutorial first as to what the heck you should do :D

I used "background extraction", "banding reduction" and "photometric color calibration" in Siril, and after that I played with some more with levels, shadows and highlights, contrast, black level etc. in Gimp.

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.
