2020年4月17日 · M64 and IFN - posted in DSLR, Mirrorless & General-Purpose Digital Camera DSO Imaging: This is my first time ever capturing IFN. Its nice to know that it can be done with a DSLR, even if it takes way longer than using a CCD.

2017年3月7日 · Here's my latest deep-sky image, which likely gives you a first-time look at the faint high galactic cirrus clouds (IFN) in this area of the sky. Larger version: https://c2.staticfli...00d92dc77_o.jpg. The small spiral galaxy near the …

2023年4月8日 · So here it goes, the far-away M64 and more local IFN shot with my old QSI583wsg before it died. A total of 17 hours and 40 minutes of LRGB exposure from my snowy observatory in the woods. Larger version can be found here: https://astrob.in/6flcei/0/ Optics: Takahashi Epsilon 180ed. Camera: QSI 583wsg. Mount: 10Micron GM2000 HPS.

2023年4月9日 · However recent software developments has made it easier to isolate the problem in a way that makes it easier to fix. So here it goes, the far-away M64 and more local IFN shot with my old QSI583wsg before it died. A total of 17 hours and 40 minutes of LRGB exposure from my snowy observatory in the woods.

Here are two sketches of IFN near M64, one at SQM 21.1 and one at SQM 21.4, illustrating the overwhelming impact of dark skies. I have developed observing processes for IFN. These are key to exploring regions for potential IFN.

Integrated flux nebulae are a relatively recently identified astronomical phenomenon. In contrast to the typical and well known gaseous nebulae within the plane of the Milky Way galaxy, IFNs lie beyond the main body of the galaxy. Luminosity channel for this image was taken from dark skies of Cherry Springs State Park in the beginning of July 2024.

2024年5月8日 · M64星系（黑眼星系）位于后发座，距离约1700万光年，其明亮的核心周围有大量黑暗的尘埃云带。 在尘埃云带的影响下，星系整体呈现土黄色。 照片中M64星系下方有一条非常暗淡的IFN，在这宁静而深邃的宇宙背景中，犹如但丁所描写的冥界里的阿刻戎河。 而上方的M64星系就像是亡灵摆渡船，孤独地航行在这条冥界之河上。

1 天前 · This is M64, the Black Eye Galaxy, in Coma Berenices, a widish view showing the band of IFN nearby. I've tried to do the galaxy justice, but the resolution isn't ideal, and getting nice detail in it while bringing out IFN is tricky - it looks a bit like a flying saucer above the clouds. I would guess there are effective ways in Photoshop of ...

Region around M64 and the nearby IFN taken in 2023 with my own setup which is installed in Spain for remote use. 494 x 5min Total exposure of more than 41 hours

2016年5月31日 · I've discovered IFN immediately south and east of M64. There is a spur of galactic cirrus or Integrated Flux Nebula that stretches into the eastern portions of Leo and on into Coma Berenices. It runs adjacent to M64. My first sketch shows the dim glow under SQM 21.1 skies; the last sketch shows how much more can be seen in better skies of SQM 21.4.
