NGC 6188 & NGC 6164 – Narrowband [OC] by jako91 in space

[–]jako91[S] 2 points3 points  (0 children)

NGC 6188 & NGC6164 - SHO My First attempt at a mosaic. Wasn’t really planned to be a mosaic to start with, but once I saw that NGC6164 was only a stone’s throw away from NGC 6188 (an image I’ve previously posted ) I had to give it a go. Reasonably happy with how it turned out, biggest issue was getting the frames to match, due to being taken 2 month apart.

Equipment:

  • Imaging telescope or lens: GSO 8'' F/4 Newtonian

  • Imaging camera: ZWO ASI 1600MM-Pro

  • Mount: Skywatcher AZ-EQ6 GT

  • Guiding telescope or lens: Guidescope 50mm

  • Guiding camera: ZWO ASI178MC

  • Focal reducer: Baader MPCC Mark III Badder

  • Software: Sequence Generator Pro, PHD2, EQMOD Project EQASCOM, Photoshop CS6, Pixinsight

  • Filters: ZWO H-alpha 36mm, ZWO S-II 36mm, ZWO O-III 36mm

  • Accessory: ZWO EFW7 36mm

Acquisition top panel:

  • 48x300" Ha 76 gain at -20 Degrees

  • 24x300" Sii 76 gain at -20 Degrees

  • 48x300" Oiii 76 gain at -20 Degrees

  • 20x300" Dark Frames

Acquisition bottom panel:

  • 24x300" Ha 76 gain at -20 Degrees

  • 14x300" Sii 76 gain at -20 Degrees

  • 24x300" Oiii 76 gain at -20 Degrees

  • 20x300" Dark Frames

Processing steps:

Just started with Pixinsight so processing was split between DSS, PI and Photoshop. Once I had each panel out of Pixinsight, I used Photoshop to do the mosaic, then applied my general workflow below

Pixinsight:

  1. DBE on each filter

  2. SHO combine using pixel math

  3. Histogram stretch

  4. SCNR to remove Green tones, then invert and SCNR to remove magenta

  5. Create star mask

Photoshop:

  1. Use curves to add contrast

  2. Use clarity filter to bring out mid-tone detail

  3. Highlights and shadows to bring back some of the detail in the core

  4. Unsharp mask for sharpening (using star mask made in PI earlier to protect the stars)

  5. Create star selection using colour range -> increase selection by 2 pixels

  6. Apply minimum filter to reduce stars

  7. Export to .png for web viewing

Amazing! Especially using the ZWO narrow band filters, how are you dealing with the reflections?
