NP127is: Return to Imaging over Taos, NM

Back in March 2019 this blog featured a Tele Vue-NP127is APO refractor image gallery by astrophotographer Jerry Macon. All those images were done with red, green, and blue (RGB) filters or a dedicated color camera. Jerry has since added the Hubble Palette filters (SHO: Sulfur II, Hydrogen-alpha [Hα)] and O III) to his repertoire, and the color camera is no longer used. We feel Jerry’s imaging has evolved to another level of perfection in the past two years. So in this blog, we look at some of his latest work with the NP127is.

Sh2-240 (Simeis 147) Supernova Remnant – SHO by AstroBin user Jerry Macon. All rights reserved. Used by permission. Imaging was done with the Tele Vue-NP127is APO Refractor using Tele Vue LCL-1069 Large Field Corrector through filters and ZWO ASI6200MM-PRO (3.76 μm pixels) camera on Paramount ME II mount with absolute encoders (unguided with no dithering) under Bortle 3 skies in Taos, NM. The software used was N.I.N.A. and PixInsight 1.8. Filtered sub-frames: Antlia Hα 3nm 50mm: 142×200″, Antlia SII 3.5nm 50mm: 145×200″, and Chroma 3nm OIII 50mm: 145×200″ for a total integration time of 24h.

Cataloged as Simeis 147 and Sharpless 2-240, the name “Spaghetti Nebula” is its most descriptive moniker. This nebula is huge: it spans 3° (6 full-moon widths). It is the remnant dust and gas of a massive star that ended life in a supernova explosion. In this case, it left behind a pulsar (a radio-emitting, spinning neutron star). Due to discrepancies between the estimated age of the nebula and pulsar, some posit that two supernovae explosions happened in this region some time apart. Whatever the history of the object, we can say Jerry’s Spaghetti Nebula is quite tasty to the eye.
