IC 434 – Der Horsehead -Nebel, der über 36 Stunden von meinem Stadtdach geschossen wurde

Wow this is gorgeous. I love the detail when we zoom in.

This is the level of detail we can get from a consumer available telescope and camera? Jesus.

Making this for my wife’s aunt. I took more than 40 hours of data total, but ended up culling about a third of my subs to keep just the sharpest ones (by star count and fwhm).

Taken with a William Optics Pleiades 111 on a AM5N mount and ASI2600MM w/ Chroma filters.

This is HSB palette – narrowband except for using regular visual Blue instead of Oxygen, since there isn’t much Oxygen in IC 434

Roughly 20 hours of Hydrogen Alpha data using 300s subs
Roughly 15 hours of Sulfur data using 300s subs
Roughly 30 mins of Blue data using 60s subs

Stacked in Pixinsight w/ 2x drizzle
Bxt, nxt, sxt then 2x downsample
Stretched
Lrgb combo adding Ha as the Lum layer
Export to DxO for color, cropping, and final edits

So is this true colors or did you apply a filter. NASA has colorized so many of its pictures I dunno what’s real and what isn’t anymore.
