Hi

My first serious go at a narrowband image taken over a few nights from my back garden in not-so-darkest North Staffs

Ha: 30 x 300s

OIII: 28 x 150s

R: 22 x 30s

G: 22 x 30s

B: 22 x 30s

(I also took a whole load of L lights but didn't use them in this versions - still feeling my way in to NB imaging)

RGB lights used for star colours only.

Calibration: Bias and flats, no darks (dithering)

Ha used for Luminace and Red channel

OIII used for Blue and Green channels

Equipment list in sig

Is it allowed to add a new version - just had a go at reducing cyg 52 a touch...

Still not sure if this is allowed in the rules, but I'm posting a newer version.  Just a levels change to bring some of the noise down, really.

Nicer.  Especially the background sky colour.  But I'm not sure if you've lost some finer detail?

Thanks, Chris.  You're probably right.  I've pulled back some of the details but not sure if it's acceptable to keep posting changes in this thread. 

Oh well, either I've already broken the rules or it's OK, so maybe one more...

Very nice, final version is great! Just edit your first post and add only the finished version.

I would edit my first post but I don't have the option for editing it.  I think there's a limit on how long after the post it can be edited.

      Hi everyone!
      The Tadpole Nebula and the Flaming Star Nebula captured over three nights of the unexpected nice weather we had a couple of weeks ago.
      A number of firsts with this image:
      1. My first mosaic - keeping it simple with two panes!
      2. First time I left my imaging rig outside... (I used a telegizmo cover) and it was perfect, allowing me to get imaging very quickly on each night
      3. First time using powerful scripting tools in my capture software, APT, to move to the second pane and starting imaging automatically...worked really well!
      APP was used for pre-processing and stitching the mosaic together, while Pixinsight was used for image processing. A total of 10.9 hours integration time.
      Full details on Astrobin
      Thanks for looking!

      Here's my effort from 2 nights ago under an increasingly rare clear and moonless night
      1hr each of HA:OIII;SII using a  Skywatcher esprit ED80 and ATIK 460 camera.

      Hello from Florida, 👋
      I wasn't able to image the 4th and final day as AR2729 rounded the limb due to work, but I was able to latch on for three days while it had lovely visible umbra. This is spanning December 5th, 6th and 7th. Imaged in 6562.8A wavelength.
      B&W:



      Colored:



      Captured with:
      Celestron 150mm F8 Refractor (CR150HD)
      Daystar 150mm ERF
      Daystar Quark Chromosphere
      ASI174MM Camera with 2" GSO 0.5x Focal Reducer
      Very best,

    • By Rob63
      EQ6-R Pro, ASI1600MM, ED120 + 0.85x reducer, Astronomik 6nm Ha filter. 2 hours integration (30x240s) 50 darks, flats and dark-flats.
      Windy night, near full moon
      Captured via SGP, Guiding PHD2, Processed in photoshop.
      This is why I wanted to get into narrowband imaging, Taken on Sunday night from south Edinburgh (Bortle class 6) with a nearly full moon in the sky (95%) and I can still make the most of the limited opportunities we get here.
      OIII filter is next on the list.

      I am going through the motions of properly processing my first narrowband image.  Perhaps there is no difference here to LRGB, but I am curious as to which method people favour for their work-flow and why:
      A:  Combine the channels (using SHO palette in my sitution) and then apply DBE; or
      B:  Apply DBE to each channel and then combine?
      Mainly interested in nebulae.
      Thanks in advance for any thoughts on this.
