M104 The Sombero Galaxy

My sky cleared at around 9:00pm. It was completely clear without any clouds that I could see. So I hauled out and set up my gear.

I've been wanting to image M104 so I thought this would be a good opportunity. Also M104 was located in a good position in my sky.

After taking 3 or 4 test images to try and get a tight focus. I also took 3 test images trying different iso and exposure settings

to see what I thought would work. I then set my computer to automatically take 15 images and I went inside to

take care of a chore that I had to do. When enough time had elapsed for the 15 images I went back outside to check what I had gotten.

When I went outside I noticed that the sky was completely clouded over and not one star could be seen. That is the way the sky stayed

the rest of the night. Out of the 15 images I took 8 were starless images of clouds. To add insult to injury 4 of the cloudless images

had tracking problems so I only got 3 usable images. To say I was pissed off would be an understatement. However what I described has

become pretty much the norm for the past five months. I decided to combine my test images with my 3 usable images in Deep Sky Stacker just to

see what I would get. As it turned out I did get an image but it leaves a lot to be desired. As to be expected noise was a big problem

with such a short integration time. With all that said please enjoy my most recent image of M104.

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.
