Quote While visiting relatives and celebrating new years eve I took my astrotrac and a new telescope with me. This was first light for the new william-optics zenithstar 71-tube. It was pretty tiresome to do astrophotography while running in and out of the house to be social Smiley Also, all the lights and sound/vibration from the new years eve fireworks (yes, I was out with the telescope at that moment!) didn't exactly make it any easier. Anyway I think it turned out OK given the circumstances (the stars are a little elongated which is due to the polar alignment being off pretty much). This night I also tried to find the Jupiter-moons Elara and Pasiphae. After collecting all the necessary exposures and doing all data processing, they did not show up on the final images Smiley I think I'll need to try those with a bigger telescope and without having people all around me shooting fireworks!

FactsA nebula is an interstellar cloud of dust, hydrogen, helium and ionized gases. Nebulae are often star-forming regions, in where the formations of gas, dust and other materials clump together to form larger masses, which attract further matter, and eventually will become massive enough to form stars. The remaining materials are then believed to form planets, and other planetary system objects.Factssource and more information wikipedia
