Description

The big emission nebulae in the central milkyway come in double packs. Norternmost Eagle and Swan, then Lagoon and Trifid, and next to the Scorpions sting Cat Paw and Lobster nebula - not visible from my home in mid northern Austria. Like the other ones, they are superimposed on milkyway's central rift, sitting in front of the big dark zone. At bottom left you can find tiny Bug nebula, a bright planetary that is a nice view in any telescope - while Cat Paw and Lobster are strong Ha emitters and visually less obvious than their northern colleagues.
