NGC6727, From Dark Skies

[Zuts]

Hi Guys

I wasnt happy with my previous effort on this, so jumped in my car and drove 100 km down the Hume freeway. This is my first real go with the SBIG under dark skies. Sydney skyglow was still visible but nothing compared to the LP in Glebe.

This image was taken exactly the same as the previous one. I did not bother re-using that data for this image.

I am quite happy with the result, I still have a lot to learn about processing though. Still, the dark sky data made this image far easier to process.

6 by 600 sec subs, darks plus flats, UV/IR block
TV85, TV 0.8 reducer on EQ6, self guided with SBIG 2000 XCM
Levels and Curves PS2, Sum combine in Maxim, Neat Image
Reduced to 1200 pixels, 30 % compression.

Thanks for looking, any comments appreciated.

I have included a full res image here, thanks for the suggestion Fred

Wow, nice one Paul! Definitely a big improvement.

Where did you drive to? How do you power your setup on the road?

[RB (Andrew)]

A very nice result Paul, well worth the effort driving so far to escape LP.
The large version has very nice detail.

Thanks Mike.

I just drove down the F5 for about 100km until I came to a reasonable rest area and setup there. Because its still close to Sydney not many people came in.

On the road I power my mount and dew strap with a 26 AH jumpstarter and the camera and laptop with a 26 AH deep cycle battery from JCAR (90 AUD).
I also have a small 4 AH battery for the Robofocus.

This setup managed to power all my gear from around 8pm until 5am in the morning. I dont use inverters and have a DC/DC power supply for the SBIG and a dick smith DC/DC power supply for the laptop.

Dark skies make all the difference. Maybe from now on I will stick to L RGB in Glebe, for nebulas. I have a Ha filter and want to try my OIII filter as well, then add the Ha to the red channel and the OIII to the green.

Hi Paul, the dark sky makes all the difference. The dark nebulosity really jumps out at you and is very spectacular.

The globular seems a little overdone but I suppose that was the trade off to bring out the nebulosity.

All in all it is a very fine image

Cheers

Thanks Ric,

Dark sky does make a heap of difference. You cant do everything in narrowband, this area has very little Ha. I was processing for the dark neb and didnt worry about the glob. Maybe becuase the background is dark enough i could process it seperately and then put it back.

Paul. Sharp as, smooth as, and hi res, very well done. Now you do yr images justice. And its worth a dark site trip on occasson, as you have shown.

See.......the free site build was easy yes?. There are a few mega pixel DSLR users here that could take yr example, such a waste.

Lovely image Paul. There's quite a variety of objects in that.

that is a pretty picture all right-shame the core of the glob blew out-maybe you can fix that in processing?

Thanks for the comment Fred. In this case yes, I am glad I went dark sky. I should do it more often. Thanks again for the google pages tip. Very easy to use, I cant seem to move the images around once I load them but maybe thats my browser, i will pereservere as its a nice easy and free way to display my images.

Thanks Peter.

Yes, the image is quite interesting. I am looking forward to the horsehead later this year which also has lots of interesting objects for widefield.

Thanks Seeker,

Yes, the core of the glob is a bit blown out. I have some other data from my dark sky trip which i want to process. After that I may have another go at that bright glob
