Hi Folks
Otherwise known as the Tulip Nebula, I have once again gathered much of this data during the last lunar cycle, with many of the subs being 1 hour in duration - and still managing to pull out 1.6 - 1.8 raw FWHM.
Very little OIII again and it was all isolated to the very centre of the 'tulip'.
Total of 26 hours (SII - 8, Ha - 9.5, OIII - 8.5). Planewave CDK 17", Apogee U16M, Astrodon filters
and while it doesnt quite compare to the APOD on 26 Jul taken with the 0.9m at BYU, here it is.
