M13, Hercules Cluster. Total exposure 2.2hrs in frames of 30s, 60s and 300s. In the image, two galaxies are visible: NGC 6207, down to the left of the cluster, and the faint IC 4617 about half way in between them.

Very nice, Jose. You've really got the bug, and I don't mean Covid!

 

Not sure if this is a monochrome image. If not, you might want to look at some other images of M13 in particular and globulars in general--they have a surprising amount of colorful stars. M13 has lots of blue and yellow.  I found it quite surprising, since visually I certainly don't appreciate the colours. From this jpg image, to my eye and taste it seems like the background is pretty dark. How does it look with a bit lighter background? I suspect you will see more of the globular's fainter stars/glow if it is backed off a bit. I find globular clusters quite challenging to capture and process; focus is critical and processing challenging to get the best  resolution, colour and overall aesthetic.

Great image! Is this monochrome?

I remember the OP's stunning "1st pic" Horsehead. That was mono so presume he just has a mono setup.

Thank you for your comment, Norm. Yes, I only have a monochrome setup for now and the image is monochrome. I only started taking images in early March so this has been a fast paced learning adventure for me. I will follow your suggestions to see if I can improve on this image.

Thank you, Shaun, yes I can only take monochrome images to date although I just got a 2" filter wheel. I am learning fast and hopefully will be able to compose color images from my main B&W camera and narrowband filters soon. As I did B&W photography for many years as a dedicated amateur, I am always in love with this type of rendering, although a globular cluster is limited from that point of view. My previous images, the Horsehead Nebula in particular, presented a better opportunity to do justice to the scene.
