Here's a picture of the Orion nebulae I took [OC]

It was taken with a Canon 6D + Tamron 600mm lens on a star adventurer tracker with some active guiding via a guidescope camera. Pretty basic setup for astrophotography :)

Wow, that's amazing! Did you need to something weird to get that result? I have been considering getting a 600mm lens for a while now, is that really all it takes to get these kinds of results?
- Two things help a lot:
  Tracking, either with a proper telescope mount or as I did, a star adventurer. You align it using the pole star, then it rotates the same speed as earth, counteracting the rotation so the sky stays in the same location relative to your camera.
  Stacking, even with tracking I typically dont get longer than 1-3min exposures. So instead take multiple and stack the images in software. This image is 14x 100s exposures.
  But, even without any of those, I've taken images of the Orion Nebulae with just a tripod. It will be a lot blurrier and noisier and generally worse, but its pretty cool to see it show up anyway.
  
  Here's my first picture of this Nebula, it's just a 400mm lens and a tripod. One 2.5min exposure.
  
  Thank you! That helps a lot to make sense of things!
