Spaghetti Nebula
The Spaghetti Nebula, also known as Simeis 147 and SH2-240 is a supernova remnant (SNR) in the Milky Way straddling the border between the constellations Auriga and Taurus.
This is a very large nebula, about 3 degrees across in apparent diameter (6 full moons across the sky). Some 40,000 years ago, a massive star exploded and left this expanding shell of gas. It is approximately 3,000 light years from Earth.
Experimented with various narrowband options - SHO, HSO & HOO, also with using Ha as a luminance frame. I don't think that the luminance option added anything to the final image so I have only included those images without luminance. My favourite is the SHO blend, but have included HSO and HOO as reference.

Comments
Thanks for your comments John
Nicely done, Michelle! I agree that Ha is seldom a good luminance for SNRs, given their typical separation of emissions. I also like best your full-spectrum, SHO palette in which Ha green and its secondary yellows and cyans are not totally suppressed.
