Will the orion nebula look good with a pair of 10×42’s

  1. I used to use 10x50s for it and it worked well enough for me in a bortle 7. Practice positioning to not have the binos move so much in your hands. I propped my elbows against my knees while sitting against a wall.

    You might but it will be pretty faint I think and thats assuming the glass is halfway decent. Cameras have to take 10s+ exposures stacked to see the nebula well. Your eyes have incredible equivalent dynamic range due to the computation your brain does (around 30stops) but they don’t integrate all that well, typically only about 1/15s give or take. The bigger problem is the focal length or field of view. Your eyes are roughly 35mm or full frame, so the 400mm glass is not very much “zoom” as far as telescopes go. The Seestar S50 is about a 1600mm 35mm equivalent due to the cropped sensor or about 4x more “zoom”.
