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.

      Finally completed my SHO version. There is some purple in the image I cannot figure out how to get rid of and I'm sick of playing with it. Hints and tips on how to get rid of it welcome, I'm using PixInsight.

      Hello Astro Peeps, I hope everyone is all good! Isn't there some amazing images on this site and others. Amateur imaging has never been so good!
      I myself have finally managed to get some data for an image, of which I am very happy. It has been so hot here it has been impossible to get any good data. One day a couple of months ago, I hung the thermometer from the grape vine under the back verandah and it was 47.5°C. Sounds far fetched, although true. I live in Adelaide, South Australia and we are 11km from the CBD and usually 1.5 degrees hotter than there!
      Anyway, I thought I'd try my hand at a Ha, OIII bi-colour image while waiting for my SII data to come in. There seems to be a halo issue with some of the filters for which I will need to do further testing so I apologise for their distracting nature. Details are with the image but basically 3hrsx15min subs for each channel.

      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,
