( This is an update of my image of NGC 4945 with an additional 22 x 360sec images at ISO400. )

 

NGC 4945 in the constellation Centaurus is a large spiral galaxy about the size of the Milkyway and around 13 million light years from Earth. It is shown here nearly edge-on and is accompanied in the image by a number of far more distant galaxies; the brightest of which is the 10th magnitude elliptical galaxy NGC 4976 (centre left of the image) which is around 30 million light years away.

Lovely image. Interesting you decided not to reduce the stars. I like it i really like those brilliant blue stars in the foreground. Nice colour control.

Thanks, much appreciated.

As for reducing the stars... well not really a decision so much as lack of skill and knowledge about how to go about it.

      Hello to all!
      Posting a photograph of the Summer Milky Way band that I took last week.
      However, I do not know how should I feel about this!
      This is when the band was right overhead, which is a rare sight for us and happens only when monsoon season is delayed. There was decent glow towards horizon but literally nothing at zenith.
      19 degrees north latitude, around Bortle 3 level sky, taken using Nikon 5300, basic lens.
      And with this, I prepare to have no view of stars till September ends

      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! 😂 😂 😂

      Hello to all!
      Just posting some of the images I took recently!
      (Total first attempt from someone who can't even hold a camera properly)
      I was out to conduct a public overnight sky observation event, which was the last event before 6 months of monsoon. For a lot of time, we had cloud cover too!
      These images don't include much of editing more than just some basic stuff in cellphone. I forgot to take the photos in RAW so either way I can't do much!
      Quite happy with the first attempt. Will improve even more in next season!
      Nikon 5300, with the basic 18-55 lens.
      Any suggestions appreciated!
      Thanks!

      Looking for the 2" low profile extension tube that is provided with most of the skywatcher scopes. I have a used 190MN that didn't come with the extension tube and need it to get accurate focus. 
       
      I believe Orion scopes may have one too.

      The weights from my NEQ6 are beginning to look scruffy.
      Is there a good colour match car type spray that anyone would recommend for sprucing them up.
