Late Summer Snowball

NGC 7662, The Blue Snowball, a planetary nebula in Andromeda
Sketch and Details by Oscar Ll. (Nickname: almach)

NGC7662 is one of my favorite planetary nebula for one simple reason: I can see a delicate blue color on it, something unusual in deep sky objects. The sketch was made with a HB2 pencil with a little help of a white snowball cotton… on white paper. After this, inverted, colored the planetary and modified some paremeters with Photoshop Elements.

For the main sketch I used 69x. With this magnification I can see clearly the color. With 250x (the theorical useful magnification limit of my telescope) I can see more detail of its structure, but I “loose” the planetary color.

For more details of my observation you can visit my blog.
