This lens is incredibly sharp and produces nearly no coma. Also the image is super flat and the lens also works for full frame cameras. For its high image quality it‘s also used by some more advanced astrophotographers.
As I bought it new for 400€ this was a no brainer because we can also use it for ‘normal’ photography.
I‘m sure your lens works well for many nebulae!
Thank you! Andromeda is way bigger than most people think. That’s the reason why it is a very (maybe the most) popular target for beginners. Also there went a lot of processing into the image, so don’t let the image deceive you from the actual conditions where I live (Bortle 5 zone)
The lens is the telescope in this case. But as the focal length of 135mm is fairly short it works best for objects appearing very large in the sky. Astrophotography can get very expensive very quickly, so we try to make the most out of the equipment we have. Just like with the 3d printed mount.
Glueing and screwing the parts:

Very interesting, thank you for sharing. Your linked gif makes it very apparent that it was indeed a satellite.
I also searched in Stellarium and found a decommissioned military satellite called STSS Demo 2 that fits the path and time stamp perfectly.
-9 magnitude is insane, must’ve been a very cool sight.
