The North American and Pelican Nebulae are two showpieces in any astrophtographers album. To frame both nebula, recquires a focal length of 200-400 mm when using an APS sensor/digital SLR. Longer focal lengths record better details but require multiple images to create a mosaic. This image was taken with a Zenithstar 61 (FL 360 mm).
This image is a mosaic of seven images taken with an 8-inch F5 reflector and ASI 2600 MC camera.
