NGC6188 captured with ASI071, STC duo filter. 12.5 hrs of 10min subs. Processed with PI and stars removed with starnet. Really appreciate some feedback, I got v.little on the other forum
Wow Chris.... I mean really wow ! That looks absolutely amazing.
When you do the star removal, it is possible to keep a couple of the brightest stars or is it all of nothing ? I just wonder what it would look like with a couple of feature starts ?
Looks great to me Chris but I do rather like stars in an image. I know it is a bit of a fad at the moment and given the shape of some of my stars one could wish for their absense however their total removal to me seems a strange approach encouraging the viewer to marvel at their absense as a thing of beauty ... I cant get to that place unfortunately... however what remains in your photo is indeed breath taking. I also ask is it possible with the removal software to remove the stars and replace them with pin point light sources...I would like that.
Chris,
I agree with that Alex, it is definitely an interesting concept and certainly helps honing in on the body of the image being the nebulously and space dust. The contrast and colour is very eye catching. You’ve put some time into this capture and it shows. I still like to see space shots in its pure state and that’s with the stars included.
Great image none the less.

Yes. Beautiful and perfectly captured with a lot of dedicated time. Can we see it with all the stars? I think if the camera firmware somehow partially occluded the large stars using a previous image during exposure that would be useful.

Thanks all for the comments. Really appreciate them !
Thought I'd put up this version. I have the same shot but with stars over in the Deep space images. It's interesting the difference between shots with and without stars, and how people react to them. I do like stars, but in the end I think what an area of sky actually looks like is what a famous TV philosopher (not Eddy Macguire) calls our "take home reality". Nothing is absolute.
It's taken me ages to get to this stage - trying narrow band type processing on shots taken with my OSC camera and duo filter. It's one hell of a learning curve - star removal, luminance and colour combining etc etc etc. But loads of fun and I've learnt a lot more about PI
My first few weeks at this were disastrous. I was getting rubbish images and horrible stars. So I then got on to star removal. I'm still struggling with it. The next step will be putting nice RGB stars back into it.
The starless pic has the "ooooh" factor. It has an air of mystery and presence because the removal of the stars give a greater feeling of being there.
I love it.
Like the image with the stars as it should be unless there’s a reason for the image to serve a purpose? even if the stars are not quite right in the corners.
To enhance the nebulosity perhaps?... The pursuit of perfection? Art?
Each to their own. I still like viewing the images you guys put up daily though.
Honestly neither image do it for me. You've got the nebulosity nice but really needs its colour stars in place.
Removing stars has long been part of my workflow but only as a way to be able to stretch the nebulosity without stretching stars. I use a piece of my star removal process to sometimes "reduce" the stars near the end of my workflow if I want to adjust the balance of stars and nebulosity. Stars gone is just a helpful step to me, not a result. Those white stars really look like they've been overlaid in the second image rather than a natural part of the structure.
Thanks Sil and Alex. Sil, removing the stars was hard enough. And as you say I've found it a great way to assist with processing the nebulosity. But I'm finding putting them back in difficult - they always look, well, just shoved back in. Anyway, one step at a time. I'm still trying to figure out the work flow though.
Trouble is Rowland, that the stars through OIII are larger than H-alpha. So I end up with large OIII flavoured rings around the larger stars.
... all part of the learning curve
The original starless image truly reveals the twisted molecular cloud formations, without the distracting stars.
Good subject for starless technique - well done!
Thanks Andy, starnet was the breakthrough for that.
Gavin, there's 12 hours in this. Also it basically comes out all red with this OSC camera if I don't use the duo filter. The Ha dominates. With the duo filter I separate the Ha and OIII then push the later.
