Astrophotography from Ursa Major Observatory @ ROSA

CEDIC team goes La Palma II - Introduction 
La Palma is a wonderful place for astrophotography: More than 200 clear nights per year at an altitude of 800m and more than 300 clear nights per year at the top of Roque de los Muchachos, no light pollution, comfortable night temperatures and only 4hours flight distance from Central Europe. With a latitude of 28 degree, all southern objects culminate more than 20 degree higher than in Central Europe.

During a time span of one week up to eight cameras were running in each night. Planning and coordinating this huge number of different setups within our team was a true challenge, which we could only master by using the planning tool of CCD-Guide ( During the day and in the evening the sky was often cloudy, but in the night the sky cleared almost always up and therefore, we could gather raw data for more than 40 images within our one-week stay. We grouped our results in 4 different parts:     Part #1: Autumn Sky     Part #2: Dust in Taurus     Part #3: Orion’s Nebulae     Part #4: Nebulae in Monoceros    
In the past, the infrastructure for high-end amateur astrophotography was underdeveloped, and astrophotographers were forced to bring their own equipment to the island of La Palma to be able to create astro images with high quality. It was always our dream to do astrophotography directly at a finca at La Palma with high-quality equipment without the necessity to book excess baggage. In the new moon phase in July 2017 the CEDIC team had been already observing at ATHOS Centro Astronómico, a finca in La Palma, which offers besides an excellent sky and first-class equipment also an outstanding service (both in astrophotography and in accommodation). Since our first trip in July was suffering from Calima (a hot, sand laden wind that blows in from the Northern Sahara), the CEDIC team (, consisting of Christoph Kaltseis, Bernhard Hubl and Markus Blauensteiner followed the friendly invitation of Kai von Schauroth for the second time to visit Athos. The second trip was undertaken in the new moon phase in November 2017 to capture the objects of the winter sky at comfortable ambient temperatures.
We could use the following equipment during our one-week stay:     - ATHOS Observatory including AP175ED (7"), TEC 110FL (4") and Moravian G4-16000 on 10Micron GM3000 HPS     - Baader APO 95/560, Niikon D810A and Nikon D850 on 10Micron GM 1000 HPS     - Pentax SDP 125 and Nikon D810A on Skywatcher EQ6-R     - SW StarAdventurer, AstroTrac and iOptron mounts including a number of DSLRs       with different telephoto lenses and wide-angle lenses
