After a long period of cloudy skies, we had very clear nights for about about 4 days, so we quickly set up the telescope to use every minute avaible. The first night was really good, so we decided to use the quadruplet and the h-alpha filter on the orion nebula (coming soon), as we already had 3h of exposure from january. The following three nighs the wind had risen (til sometimes it has blown at 45 Km/h), so the only way to make some photos was use a 50mm lens. What a better target than Orion? Hope you like it; stay safe and clear skies
