The Great Hercules Cluster M 13 - Now and then

M13 was the first DSO I tried to capture back in August of 2019. You can see the result in image B. It has been the first time for me using a DSLR, APT or a telescope with an equatorial mount (had only used a Dobson before).

The mount didn't even have a polar scope at the time, it has still been on delivery. I just tried to center polaris in the opening of the mount were the polar scope should be introduced. Therefore, only 30 second shots were possible. Focus was not spot on either.

Moreover I had no idea I had to process my images... At the time I thought that stacking in DSS would result in the final image. Of course there was a great disappointment when the stack was initially dimmer than a single sub :-) So the stack was only processed in Photoshop with a crude levels adjustment to make anything visible at all. Nobody had told me that something like a stretch or a white balance was a thing... but you know what? I was extremely proud at the end that it worked at all and keen on spending many more nights imaging.

But now I thought it was time to revisit the target to see if I can do better meanwhile. Long story short: I think I did :-) It's amazing to see how the images changed over the two years. And are still changing. Hopefully learning and progress never stop.

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.
