SH2-224 RICE HAT NEBULA
Sh2-224 is a very faint supernova remnant located approximately 15,000 light years away in the constellation Auriga. In September 2022, Juan Marin Otero and I initiated an imaging collaboration on this object and were joined by Randy Lindstrom and Jeff Ball. Over a period of 3 months, we captured more than 240 hours of narrowband H-alpha, OIII and SII filter data. This image is the result of my processing that data in an HSO palette. Each of us will publish his uniquely-processed version of this data. Other members of the imaging club have also contributed data to this collaboration are publishing their versions as well:
Randy;
Juan; Jeff
205 hours total exposure
88 hours H-alpha
96 hours OIII
64 hours SII
Imaging Rigs:
Tak FSQ106 / ASI2600 (Randy)
SVX140T / ASI6200 (Juan)
SW Esprit100ED / ASI2600 (Juan)
AT80EDT / ASI1600 (Chris)
RASA8 / ASI294MMPro(Jeff)
AP92 / ASI294MM Pro(Jeff)
Many parts of this collaboration were interesting, but the primary challenge came as we worked out how best to combine the data from our diverse rigs and locations. In the end, we settled on a methodology that produced very clean masters and that we believe is easily scalable to support future club collaborations.
