The Rosette Nebula

First light with the new Optolong L-eXtreme Pro 2″ filter last night, coupled with my RedCat51 250mm telescope. It was a clear, cool night with low humidity and above average seeing conditions… perfect to play catch up and give this toy a whirl.

Wow. I can’t believe the detail and contrast I got on the 3 objects I captured last night… the Heart, Veil & Rosette Nebulas. The filter does exactly as advertised – tone down the stars and bring up the background hydrogen and oxygen.

This 75 minutes of data (15 x 5 minutes) of the Rosette Nebula in Orion blows away anything I’ve been able to do before. Can’t wait to get the RASA on this sometime this winter.
