National Astronomical Research Institute Revealing astronomical photos made by Thai people “Banana Squid-Flying Bat Nebula” points out that it is difficult to photograph because it can only be seen during the rainy season. The National Astronomical Research Institute or ASTRO revealed the image via Facebook. Revealing photos of nebulae made by Thai people. Photographed by Ms. Wachira Thomas and received the first prize. Astronomy Photography Contest 2023, Deep Sky Objects category, with the said nebula image consisting of “Flying Bat Nebula” and “Banana Squid Nebula” which are nebulae that are rarely seen. Because it can be seen during the rainy season in Thailand. Make the sky not clear Hard to notice Observations of black hole M87 reveal the first evidence confirming that “The black hole is rotating.” The image “Ribbon of Dust” from James Webb unlocks the secrets of the universe in the era of the “Cosmic Bulge.” Revealing images including Saturn taken by Thai people over the past 8 years, the Dr. revealed that Mr. Wachira took the said image. on June 23rd Sung Men District, Phrae Province, using a ZWO ASI2600mc-pro camera, WO Redcat51 lens, aperture size 51 millimeters, focal length 250 millimeters, focal length ratio f/4.9 and setting the light sensitivity or ISO at 100 sdr., indicating that the group photo The large red hydrogen gas in the image is the area of ​​the “Flying Bat Nebula” or Sh2-129, an emission nebula located in the constellation Cepius. It is about 2,300 light years away from Earth, which hides another nebula inside, namely the “Banana Squid Nebula” or OU4. Its distinctive feature is that the light emitted is bluish-green. which is caused by the breakdown of oxygen gas It creates beautiful contrasting colors. These two nebulae It was only discovered in June 2011 by French astrophotographer Nicholas Outers. which the light of this nebula It is caused by receiving enormous energy from a massive star named HR 8119 or HD 202214 that appears brightly near the center of the nebula. The two nebulae It can only be observed during the rainy season in Thailand. Therefore there is very little opportunity to record images. Due to unfavorable sky conditions In addition, the Banana Ink Nebula emits very faint radiation. Images must be recorded only through the Oiii filter, thus requiring the accumulation of image signals for a long time. In order to clearly appear a bluish-green color, it is also stated that Mr. Wachira took 2 sets of photos, including the first set using an Optolong L-eXtreme filter to get a signal in the hydrogen alpha range with Oiii for 50 hours, while the second set An IDAS D1 filter was used to capture the light of other stars for 20 hours, for a total of over 70 hours, which was then processed by the program to bring out the most detail.
