NGC 7000 imaged from my backyard

In the night from May 24 to May 25 I used my Canon EOS 700D mounted on my Sky Watcher StarAdventurer mount to take images of NGC 7000, also known as the North America Nebula. The camera is modified and has its IR-filter (Infra Red filer) replaced by a different filter that lets pass through more red light. So emission nebulae like the North America Nebula are ideal objects to image with this camera because they principally emit light at the very red wavelength of 656 nanometers, which get blocked by the original IR-filter.

Here is a picture of my setup:

I took 40 images of 3 minutes illumination each. Then I processed the images and rejected 4 of them based on statistics that give indications about the background noise and sharpness of the stars. The final result is this

Stay tuned for more images to come in the near future!
