超新星遗骸Simeis 147

来源：成大APOD

在这张昏暗超新星遗骸Simeis 147的细致影像里，视线很容易迷失在繁复的丝状结构中。位在金牛座内的Simeis 147，又名为Sh2-240，跨幅接近三度，相当于六个满月的宽度。以这个恒星遗骸的估计距离3,000光年来计算，这相当于150光年的跨幅。这幅精彩的哈伯太空望远镜窄波段组合影像，记录了来自受到激震晖光区的氢、硫和氧原子之辐射。这个超新星遗骸的估计年龄大约是40,000年，也就是说来自这次大质量爆炸的光约在四万年前传抵地球。不过扩张的碎片云并不是此次天体爆炸事件的唯一余波，它还留下了一颗快速自转的中子星，来自残存下来的恒星核心。

天啊,这个效果是怎么拍出来的啊

网状星云。。。壮观啊。。。

学习一下，图中哪个部位是中子星？光点和背景星光融在一起，分不清楚了。

Simeis 147: Supernova Remnant（in "natural" color）

Explanation: It's easy to get lost following the intricate filaments in this detailed image of faint supernova remnant Simeis 147. Also cataloged as Sh2-240 and seen towards the constellation Taurus, it covers nearly 3 degrees (6 full moons) on the sky. That corresponds to a width of 150 light-years at the stellar debris cloud's estimated distance of 3,000 light-years. The remarkable narrow-band composite image in the Hubble color palette includes emission from hydrogen, sulfur, and oxygen atoms tracing regions of shocked, glowing gas. This supernova remnant has an estimated age of about 40,000 years - meaning light from the massive stellar explosion first reached Earth 40,000 years ago. But this expanding remnant is not the only aftermath. The cosmic catastrophe also left behind a spinning neutron star or pulsar, all that remains of the original star's core.

“这幅精彩的哈伯太空望远镜窄波段组合影像” 哪来的哈伯太空望远镜？

This is a second version of Sh-240 this year.

I added more H-a light. Now image is smooth and signal / noise is

improved. I might shoot more lights for this later in this spring.

-

Two versions, first in Hubble palette and secon in "natural" color narrowband composoite.

-

Exposures so far are:

H-alpha, 12x600s + 24x300s(binned 2x2) + 12x600s = 6h

S-II, 5x600s (binned 2x2)

O-III, 14x300s (binned 3x3)

-

Optics: Canon 200mm EF f1.8 @ f1.8 Camera(佳能相机): QHY9 @ -50 C Guiding: Lx200 GPS 12" + LQHY5 and PHD-Guiding - The information in O-III channel is extremely weak. I used a special technique of mine to dig it out for color information.

请问楼主这片子咋拍得太神秘了
