I posted earlier my version of this with stars, so I thought I'd try a starless version. Came out pretty good, but there are definitely some artifacts remaining from the star removal. I used StarNet++ to remove the stars. It doesn't do a perfect job, further retouching in Photoshop is required. So I fixed up most of the larger artifacts, but my mouse click finger got tired using the spot healing brush in Photoshop, so this is where I stopped.

 

Just like before, this is very limited data. 7 subs at 4 minutes each, for 28 minutes per filter. As a result, the image is very noisy, and probably lacking in some detail. But from a distance, it looks good! smile.gif

 

What do you guys think?

Looks great!

I bought a cheap Huion Pen Tablet for editing photos.  It is much more precise and much easer on the hands than using a mouse.  The pressure feature is very helpful as well.

Kevin, while there's a certain "painterly" quality to the starless images, personally I'm not a fan.

I liked your other one better :)

I had a Wacom tablet, but my son swiped it. I may have to get another one. smile.gif

Thanks for the feedback.

 

Actually, I wasn't planning on making this starless. I was trying a new star reduction technique, which requires a starless image blended with the original, using Pin Light blending mode in PS.

 

Maybe I'll continue, and do the reduced stars version.

So here's a version with reduced stars. I may have overdone it a bit (recurring theme for me).

And just for comparison, here's the original version with all the stars in their full glory

I like the last one the best, too -- but agree you might have overdone it a bit.  Me, I *like* stars :)

Great to experiment and hone your techniques, though.  Keep it up!

I have toyed with starless versions, and sometimes they work, but more often not.

 

Among your versions, I think what would be ideal is something between the very reduced stars in post #6 and the full-star version in post #8. Post #6 as is looks nice but a bit unnatural. Post #8 the stars are a bit much (though it's a nice image).

Thanks for your feedback Stelios.

 

When I first made the starless one, I was like "Ooh!", basically because of the novelty of it. But the more I look at it, the more I like stars. :)

 

I'm basically just messing around, trying different things, seeing what I like, seeing what works and what doesn't. Don't worry about hurting my feelings if you don't like one of my versions (or any of them!).

 

But yes, I agree, something between the two (reduced and full stars) would probably be ideal. One of the things I don't like about the reduced stars version is it lost the diffraction spikes. I like my diffraction spikes!

 

Thanks for looking!
