wbpp(debayer选superpixel方便后面spcc)跑一遍,然后对registered下的文件用CometAlignment获得无星版彗星文件,然后用imageintergration叠加(张数大于20选linear fit clipping排异,low4,high1)获得的文件存成CA,然后再在CometAlignment里面把刚才的无星版彗星文件CA作为Operand image做subtract,获得纯星点文件star。然后pixel...
早在2022 年 3 月 2 日,天文学家 Frank Masci 和 Bryce Bolin 在位于美国南加州的帕洛马天文台(Palomar Observatory)使用兹维基瞬变设施(ZTF),发现了一个他们最初认为是小行星的天体。随后的观察表明,这是一颗彗核直径1-1.6千米的彗星。当时这颗彗星距离太阳约6.43 亿千米,位于木星的轨道附近。 那时发现的这颗...
Comet C/2022 E3 (ZTF) has been very close to Earth. This poses additional problems to imagers since the comet needs to be tracked during its high-speed journey among the stars. In its closest approach, even short exposures of 2-minute length showed trailing stars: PixInsight's current tool...
▲ C/2022 E3 (ZTF)彗星,来源:Jose Francisco Hernández(APOD) 这颗彗星1月12日通过近日点时和太阳的距离大约会是1.6亿千米,2月1日通过近地点,和地球的距离大约会是4200万千米。C/2022 E3 (ZTF)彗星的轨道周期大约为5万年,这意味着它上一次靠近...
comets: individual: C/2022 E3 (ZTF)A morphological and photometric analysis of the naked-eye long-period comet C/2022 E3 (ZTF) before perihelion is presented in this study. The observation images taken by the Zwicky Transient Facility survey telescope from July 2022 to October 2022 show a ...
Managed to grab these through the 4” and 16” scopes this morning. I used a 24mm Panoptic with a FoneMate mount and iPhone 11 Pro phone using the x1 camera. I just used the standard iPhone camera app as I didn’t have tracking on either scope and this g
Why is Comet C/2022 E3 (ZTF) So Special? Comet C/2022 E3 (ZTF), more popularly known as the “Green Comet,” was discovered on March 2nd, 2022, by the Zwicky Transient Facility. This comet is unique because it has an unusually bright green hue. It is believed that the green color...
Page 3 of 4 - Comet C2022/E3 (ZTF) - posted in Electronically Assisted Astronomy (No Post-Processing): Woke up early again this time with the Vixen 8 F4 Newt. Little better detail and less noise than the 80mm. The sun started to rise on me at the end and
