Simeis 147 RGB + SHO & Paletta Hubble SHO
Simeis 147, also known as SH2-240, the Spaghetti Nebula, is a supernova remnant that spans the constellations Taurus and Auriga. It is difficult to observe due to its extremely low brightness.
The supernova remnant is very large, approximately 3 degrees in size, approximately 3,000 (±350) light years from earth. Simeis 147 is estimated to be about 40,000 years old.
Simeis 147(Sharpless 2-240) RGB+SHO & Paletta Hubble SHO was shot by Spain astrophotographer José Jiménez.

The Simeis is going to be great if you use the kit L-eNhance and RGLB + improved NG filters.
L-eNhance effectively isolates the H-Alpha, H-Beta, and Oxygen OIII nebula emission lines and achieve a maximum transmission of up to 90%. Optolong improved version of SHO6.5nm filters mainly solve the problem of halos, so you will see how great the filters they.
