Awesome Mike and Trish.. reeeally amazing depth
and resolution.
Only other image I have seen of the Helix that goes as deep and shows those intricate fine shock fronts as well is one by the
Galaxy Evolution Explorer (GALEX) Interesting that the Ha features match the UV ones so well.
Man, I wish you had a slightly larger FOV...?..mozaic perhaps
Great scope and mount and observatory you have
Mike
