Description

I shot The Little Rosette back in December 2022 as part of the field of view using the tiny FMA135. I made a note at that time to return to it with a longer focal length.

It was much harder to shoot at f7 with the C11 than I thought it would be. The Astronomy God's laughed at me every time I tried to get SII data. I could not get anything worth keeping until early February. All the other data was captured in November last year.  The weather and the seeing were just horrible in the intervening months.

Even with 7 and 8 hours of integration the OIII and SII data ended up being very noisy, but the Ha signal was strong and relatively noise free so I decided to process what I had.
