Rosette Nebula (SHO) – Alan Pham

Posted by Stellarvue on 25th Apr 2019

We are happy to share this astonishing image by Alan Pham. From a 7.00 Bortle Dark-Sky in his San Jose, California backyard, Alan “Owned the Night” with his 102mm Stellarvue Triplet APO. He had started this project in early 2018, and was finally able to finish capturing the remaining SII data and some RGB subs for star colors in February of his year. “I tried to subdue the colors a bit during processing. Hopefully, it turned out well.” Well, we sure think it turned out well Alan, and thank you for letting us share with the Stellarvue family. Alan consistently amazes us with his work.
