IC5146 - Cocoon Nebula.

Recommended Posts

I originally took this in June, with the intention of adding more time to it and have just re-processed the data. I was amazed to get anything at all, especially as the sky was not dark and I couldn't see the nebula on the raw images.

The image was stacked in DeepSkyStacker with stretching and colour calibration in SiriL. I used Starnet++ to remove stars and create a star mask and Photoshop for final processing. The stars have been reduced slightly to improve the final image.

24 x 300s, with darks, flats and dark flats. Total exposure time 2 hours.

11" SCT at f6.3, ASI294MC-Pro and Optolong L-Pro filter.

Thanks for looking!

Nicely done, can't help thinking that more subs might bring out the selection nebulosity a bit more on the left.

Thanks! Yes, it needs more exposure time, but due to the weather, it probably won't be this year.
