Description

This is a young and compact Ha nebula surrounded by some distinct dark nebulosity that appear to form a larger ring. It is surprisingly rarely imaged. Here I have used the starless processing workflow I now use on my wide-field RASA and SY135 images on refractor data collected with with Esprit 150 and ASI071 and a 0.79 reducer (65 x 5 min RGB). Luminosity was collected with the Esprit 100 and ASI1600MM (54 x 5 min). Both scopes sitting side by side on a Mesu200.
