Night Twentyfour

Image
Tried grabbing star trails above the house. So-so results for first attempt. The house faces North which places the State prison's illumination in this Southern sky view. This final result is 200 images of 30 seconds each stacked to create a sense of motion over a 2 hour period. It appears that during the two hours the telescope was collecting images, a car pulled through the cul de sac and brightly lit up the house and the landscaping.

I returned to the Andromdea Galaxy last night, it is such a rewarding target due to its large size. No enlarging necessary as it fills the screen because of its closeness to our Milky Way Galaxy. This image was 200 60 second exposures stacked . Here is the same image with the stars removed.

Night Twenty two

This is an image of the Bubble Nebula (NGC 7635). The "bubble" is created by the stellar wind from a massive hot young central star. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. It was discovered in November 1787 by William Herschel. The nebula is visible as an extremely faint and large shell around the star. Post processing allowed me to just barely bring out the dim circular ring of the expanding shell. Here is the original image from the telescope that shows the ridiculous number of stars in the area of the Bubble Nebula. One of the post processing steps, removes the stars from the image. Just above the Bubble (dead center) and to the left is Messier 52 an open cluster of stars thought to be 7,000 light years away from us.
