What kind of lens do you use and what settings??

So DSO is different than widefield (attached) which is what you were doing above. I haven’t shot much widefield (this one is out of focus), but it requires far less “specialized” gear, because you’re not trying to offset the sky rotating. Basically you want to find your fastest lens, step it 1-2 steps back from wide open (tends to sharpen the focus) and then adjust focus for infinity by zooming in on a star and checking if it’s sharp. Shot length should be 600/ focal length in seconds.

The above DSO (M42 Orion Nebula) was shot on a sigma 150-600 f5-6) on an AVX mount, but you could probably do the same but better with a star adventurer and a Rokinon 135 f2 for half the price. Highly recommend the Star adventurer, but I worked with the gear I had available to borrow from my local astronomy club and the lens that I had. Typically for widefield you shoot and enhance, and it’s a 15 second photograph, DSO is an all night activity over several hours shooting and combining photos.

I think the above widefield image I shot, was with a 50mm f1.8 pancake? (But it didn’t have a manual focus ring so it was a nightmare to try and setup in the dark) Faster is better in widefield, but focus makes or breaks an image.

Light pollution was a bit a problem for the image, but frankly the bigger issue was the clouds. If you get a perfectly clear night it doesn’t reflect half the same levels of sky glow into your image. The other thing to watch out for is the moon. If it’s up, no point in shooting anything.
