Hi all,
Had a quick go at Alnitak - i mean the flame neb and HH.
1 minute subs and half an hour of data. Will make a proper go of it when i get a light pollution filter.
30 x 1min subs iso 1600.

Cheers,

I really need to learn how to blend these high dynamic subjects or choose more consistent brightness objects!

Very sharp and beaute field again. :thumbsup: Not sure about the colours and Alnitak is a little saturated.
Nice going for a quick one Russ. I hear you mate, every time I learn something new to overcome one of my processing issues that I have had, another one crops up..... Keep at it mate you've got a good result for such short subs. Can't wait to see it with more data.

Wow. Very nice.
Not sure My ED80 would make anything of it worth while

Russell why not try layering it, mask out Altinak and insert a shorter exposure of it. Folks do this all the time on M42s bright trapezium area. I am keen to try that myself if the cloud ever gs away.

thanks Peter, I'm sure the ED80 would give a beautiful wide view!!
thanks marc, definitely an improvement I think.
Hi Glen, yes - perhaps, i'm not sure how people deal with alnitak it is a difficult one to process, mine looks a bit funny as it gave a double halo around the star - with my already short subs 1min. the darker outer halo stands out as a ring in this version and you can see it in the saturated original.
I might try loop it and try and increase the exposure here. I found after masking it I had to invert the mask and still stretch the curves a bit to help it match the brightness quite a way from the star.
I have already tried a few things to even it out such as https://www.flickr.com/photos/80336656@N07/15696371000/in/photostream/lightbox/
blurring it.
I feel as though this is harder / a bit different from the trapezium as lesser exposure leaves a black hole around the star while the trap reveals gas, stars and perhaps easier to blend. i'll definitely give it a better go when I filter up, perhaps go really short, medium and long for the curtain. :thumbsup:
