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.

Beautiful example of this object and personally I think really well processed ?

What scope and camera did you use?

It sounds like the climate there is rather "toasty" LOL - is it a dry heat so that humidity isn't such a problem with sky quality.

Anyway - really well done

Hi David,

Thanks for your comments. It only took about 5 complete fresh starts and a week and a bit after work etc. to get it to where I was happy with it. I know that Ha and OIII aren't meant to make natural colour!

I've added the image details in for those that cannot see it on the link provided in my original post.

Generally the heat is dry although it gets humid at times, although not really tropical. The problem is that the seeing is badly affected by the heat rise and some nights we were lucky to get below 25°C. Those nights the guide star jumps all over the place, which doubles the seeing error equaling a poor quality image. I share the obs with my brother and we both pulled out the scopes for about 5 weeks in the middle, it was near on impossible to do anything.

Some very nice stuff on your website, by the way!

Cheers and clears!

      Hi guys
      First things first, apologies for posting this one out of season. A combination of no astro dark, crappy weather, and being busy at work has meant that there's no imaging getting done at all these days. So, i've had to turn to old data to re-process, and this data set was an obvious candidate as i was never happy with how it came out originally. And looking back on it now with fresh eyes, boy did it need it! 
      Nikon D5300, SW 80ED, HEQ5-Pro. 
      3 x 1200s, 2 x 1380s, and 4 x 1500s of Ha
      9 x 1200s of Oiii. 
      11 x 480s with an IDAS-D1, for RGB stars only
      7 Hrs 54 Mins in Total. 

      Stacked in APP and processed in PS. 
      Combined as SHO (using a 70/30 blend of Ha/Oiii for the Sii). 
      The main differences this time were, using Starnet++ to create the starless versions, using more Ha in the synthesized Sii (70% instead of 50% last time), but mostly the improvement has come from toning down the stretch a lot (ok, a heck of a lot!) before making the colour map for the tone-mapping. From then on it was immediately apparent that i'd made a massive boo-boo first time round 🙈
      I've included a 1080p rotated crop too, as i quite liked the framing.
      Feels like ages since i last did any NB imaging. I almost forgot how much i enjoy it! 🙂 


       
       
      And rather embarrassingly, here's the original. Try not to laugh too hard! 😂 😂 😂

      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.

      Thanks for looking!
