and here is the rosette in O3 from last night

Robert Pitt

The attached Rosette Nebula in O3 (2 hrs total with 3 min subs). The soul had very little O3, even with 2 hrs, may try to add more to that later next week along with the S2. The Rosette O3 is quite a bit different from the Ha and interesting. 8 inch RASA with ASI 1600 and Baader O3 (HS) filter.
