Description

After success using the Optolong L-eXtreme filter on the widefield shot of the Orion constellation, I thought I´d revisit this area, and try for the center of the Rosetta Nebula, the central cluster of stars designated as NGC 2244.

The Nebula is a strong Ha emitter, but I wasn´t sure if I´d see much with the Dob, because I´m limited to 4 second subs, and wisdom has it that longer subs are needed with such narrow band filters to overcome the read noise of the camera sensor. But I figured  the large aperture would work in my favor (355mm).  I was stunned to see features appearing after only 10 frames/40 seconds. Far more than I could see with a standard light pollution filter, and with far more detail. 
I am very pleased with the level of detail and the range of color tones captured by this camera-filter combination.  The feature to the left almost  looks like a rose flower, with its roots forming below in the central hole.
