Ngc 6164-6165

[jase (Jason)]

Hi All,
I tribute this image to my father who lost his battle with illness on Sunday night. You’ll be greatly missed - May you wander amongst the imperishable stars.

Here is my latest effort, the bi-polar emission nebula NGC6164-6165. A wide field rendition of the fascinating Ara OB1 region showing the location of NGC6164-6165 relatively to NGC6188 can be seen here.

Located in the constellation Norma, the S-shaped bi-polar emission nebula (NGC6164-6165) forms part of the greater Ara OB1 region. Originally believed to be a planetary nebula, NGC6164-6165 is the result of ejected matter from the poles of the central Wolf-Rayet type star (HD 148937) as it passes the main sequence life cycle. Due to the star's fast rotation, magnetic field and violent winds, the gas is being expelled in a symmetric manner. While the nebulosity appears connected, the object has been granted two NGC catalogue numbers. In the image presented, NGC6164 is located at the bottom, while NGC6165 at the top. The nebula is estimated as being 4,000 light years away. To the right of the central blue star in the image (SOA 226920) is the small open cluster designated SAC Ru 120.

A few words on the image;
The image is an R[Ha+R]GB composite totaling 5.5 hours (R:120min-1x1, Ha:75min, RGB:45min each). Data acquired on GRAS008. Processed using Registar, MaximDL and PS. I decided on using red filtered exposures as the main luminance data. This was acquired over the recent full moon period as red filtered (like Ha) are relatively unaffected by the moon (which emits predominately in the blue wavelengths). I collected two sets (1x1 and 2x2) of red filtered data. On reflection, I could have easily used the 1x1 data for the RGB as well, just scaled up the G and B channels. I acquired more Ha data, but found subs were extremely noisy so many were omitted. I suspect this was related to the calibration frames. I think the image screams for more Ha data to further bring out the shock waves. I blended a considerable amount of red channel data into the Ha to reduce the noise using the lighten mode – slight trade off. Background is a little noisy, so could have perhaps been a little harder in the reduction process. Minor gradient corrected in the blue channel using GradientXTerminator. Seasoned to taste.

Imaging soothes ones soul in time of need.

Hope you like it.

i am sorry to hear of your loss

My thoughts are with you Jase, on the passing of your dad, your image would surly make him proud, top stuff.

Lovely image Jase!

Did your father appreciate your imaging efforts? ...I think he would like this Wolf Rayet star

So sorry to hear of your sad loss, Jase. I only hope that your tribute to your Dad sees his memory forever emblazoned in the stars. I know he'd be very proud of that shot....it is a great pic. Great work.

[glenc (Glen)]

Your images are superb Jase. Your dad must have taught you to do things well.

[Dietmar]

Jase,

let me express my sincere condolences on your recent loss in your family.
your father will be proud on having a son like you, dedicating this brilliant image to him.

Hi Jase,
My condolences to you and your family on the loss of your Dad.
I hope too, that he wanders amongst the celestial beauty.

[montewilson (Monte)]

Hi Jase - I am sure he was just as proud of you as you are of him. Your words about wandering the stars are very touching.

Your image is great. I saw these shockwaves in an Ha shot I did with the FSQ but there would not have been enough information in my shot to make a good colour rendition of them. I'll bet their extent wasn't well known until CCD's came into force.

Also how did you keep those bright parts of the lobes under saturation levels? I had real trouble with this large dynamic range.

Are you taking advantage of the discounts for "moon in the sky" with GRAS? I would, especially for Ha.

[Zuts]

Jase, sorry to hear about your loss, my thoughts are with you in this sad time. If only aspects of life could be as unchanging as your beautiful image.

Beautiful work, Jase. I really love the widefield version - these type of shots inspire me. The close-up version is very detailed.

The tribute to your father is very touching - as others have said, i'm very sorry to hear of your loss and i'm sure he's very proud of what you can achieve.

[dugnsuz (Doug)]

Another excellent image jase - a fitting tribute.

All the best.

Thanks Mike. Indeed, he enjoyed some of my work so this comforting. I'm not too happy with the noise, but the image will suffice for now.

Thanks Monte. I used layer masks to manage the saturation levels for this object. Indeed, trying to make the most out of the GRAS points. I've recently acquired data for M83 so stay tuned.

Thanks all for your condolences and kind words. I thought this image would be appropriate due to the WR star (HD 148937) transitioning to a different stage in its life. The process is character building.

[Garyh]

A fine tribute to your Dad Jase!
My condolences for you and your family!
Beautiful colors in the stars..he would have liked this one.
Gary

[Ric]

A wonderful image and a fitting tribute as well.

A great effort.

[marc4darkskies (Marcus)]

Sincere condolences to you and your family Jase - such a loss touches us all. I often think of my dad (who I lost 15 years ago) when I'm gazing at the stars. Your image is a very fine tribute! May the perpetual grace and beauty of the night sky continue to give you comfort.

Cheers, Marcus

[EzyStyles (Eric)]

fantastic image Jase. This is one of my favourite planetary well captured, great use of colours, heaps of details i can't see any fault with this image. well done.

Condolences to your father and family. I'm sure he will be very happy and proud.

[Alchemy (Clive)]

Lovely shot jase, nice description too,

i cant help wonder if the real fainter extension to the lower and side are connected, Nice smooth detail in the lobes looks superb.

Sorry about your loss, im sure you had many good times together, and you will cherish the memories.

clive.
