My first real attempt at astrophotography, Orion

What ISO and aperture did you use to take those 10-second pictures? And how did you follow the movement while taking the photos?
While there are star trackers (devices you mount your camera to to follow the movement of the stars) usually you have a steady camera and then align the images in post-processing with a program like Sequator, StarStax or Siril (other paid options also available).
I imagine that is possible with fast shutter speeds, but if you expose 30 seconds with a big focal length (OP used a telescope)?
It was on top of an equatorial mounted telescope. I do want to use the scope as a lens at some point but it needs a Barlow lens to focus, and that magnifies the image so much that any wind at all will ruin a picture

ISO was 1600. Looking at the image metadata, I believe f/5 is the number you’re looking for? I’m still quite new to this. I shot it with this lens, focal length was 47mm

Mounted it on top of a celestron astromaster 130EQ, which has a threaded camera mount on it. Side note, I could write a few paragraphs about how much I don’t recommend this telescope. The motor helped keep Orion in roughly the same spot for the whole 5ish minutes I was taking pictures, though
