I'm glad that you guys like it!
I have a Celestron 8 inch SCT telescope with a sky tracking mount called AVX. The white telescope on top of the main orange telescope is called a guide scope, it helps in giving the sky movement feedback to an onboard computer which improves tracking. I'm also using a One-Shot Color astrophotography camera called ZWO ASI 183mc pro. Ideally, the camera is mounted at the back of the telescope. But, in this case, I'm using it in a configuration that some might call "The RASA configuration". This makes my telescope really fast [1].
For this image, I captured 53 images with 300s exposure and another 22 images with 600s exposure. I took all of those photos and processed [2] them in a software called PixInsight.
Let me know if you guys have any more questions. Will be happy to answer. Feel free to DM me.
If there are more Astrophotographers in the group, I'd love to discuss astrophotography with you.

1. A fast telescope means that it can capture more light in significantly less time. In this case, the telescope turned from F/10 to F/2. It comes with a tradeoff though, you have to sacrifice the Focal length for it. Mine went down from 2032mm to 388mm.
2. The process is called stacking. Basically, you take a bunch of images of the Deep Sky Objects and merge them to get an image with a better signal-to-noise ratio.
