Description

20211108 - IC405 AUR - The Flaming Star - A fiery flame in the sky …

What’s in the picture(s)
IC 405 - The Flaming Star - https://en.wikipedia.org/wiki/IC_405
Quote: “IC 405 (also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31) is an emission and reflection nebula in the constellation Auriga north of the celestial equator, surrounding the bluish star AE Aurigae. It shines at magnitude +6.0.

The nebula measures approximately 37.0' x 19.0', and lies about 1,500 light-years away from Earth. It is believed that the proper motion of the central star can be traced back to the Orion's Belt area. The nebula is about 5 light-years across.”

What was the experience
Clouds for weeks … and no Clear Sky in sight … 10km more inland, the sky was wide open, but no luck at my Bortle 6 place … until a fluke opening in the sky. Hazy, but worth the chance. Scopes outside in a fast drill and just for a couple of hours, a quick capture of photons, until mid-way through the night, cloud cover rolled in again. You need to saviour the moments in life when they present themselves 😉

How it was done
Scope: TS-94 APO (FL 414mm)
Mount: EQ6-R Pro
Camera: ASI2600MC Pro
Filter: L-Enhance
Photons: 300s 30x
Darks/Flats/Bias
Processing: PixInsight (Mac)

What have I learned from this
Building up the processing experience, and enjoying the moments. Straight rgb processing, although the L-Enhance skews the colouring of the Nebula, and a blueish hue in the middle, in spite of the proper curve/HST trimmings. The image could do with more integration time, but given the short opportunity, I wanted to divide the time across a couple of DSOs, wanting to make the most of it. Expansion on the integration time planned for the next clear sky.

Clear Skies everybody! 🤩✨🔭

Title: Re-processed, stirring up the flame, making the fire burn higher, as a straight HOO-palette

Description: 20220119 - Cloudy Nights = Education time 🤩 - Re-processing ‘old data’ in a new way … as 'straight' HOO-palette, splitting the L-Enhance image in Ha(R) and Oiii(G) component, didn’t boost the Oiii component in this pass, applying the fornaxx-formula, using Ha as Luminance. Learned to apply ACDNR in better way, which has made the image less noisy. Been very soft on the curves transformation. Happy that the fine nebulosity in the background is better visible. Overall a much better result compared to version 1 … I hope 😉
Maybe I’ll try and boost the Oiii in a future pass …
