Catch a Star 2003

 

OBSERVATIONS OF M 27

We have observed the Dumbbell nebula with a telescope Schmidt-Cassegrain of 8" with the next characteristics: focal of 1280 mm, diameter of 203 mm, eyepiece of 40mm, in other words a enlargement to 32x. We saw a blurred patch with more or less the appearance of a core of apple.

We have taken 5 photos with different times of exposure: 6 min, 7 min, 10 min, 11 min, and 20 min. Only the photo with a time of exposure of 6 min present no trace of movement, but the colours are less visible. The photos of 7, 10, and 20 minutes shows the colours, in spite of the fact that the telescope didn't follow exactly the nebula movement.
