Details at link above

I am having a lot of fun seeing what I can get with the data I have. 

Learning and experimenting with tools in Pixinsite to eke out details without over doing it.

C/C welcome.

Mike

Very pleasing processing elmiko.  Is there a way you can get more colors in your stars?

Looking Real Good!

 

Have you tried longer and more exposures?

 

I have the same mount as you and I am up to 20 min subs. It really makes a big difference in processing and the final image.

I tried to get more color in the stars, just didn't get it? Usually I don't have any problems?

Thanks for your input Gipht.

Thanks PirateMike, I use 5 minute subs for fear of over saturating the stars. I tried 10 minutes before and had to throw a lot away because of airplane lights. I definitely could use more subs. 

My goal is to get 5 hours on a target. I just didn't achieve this the night I captured this target. It was moving west into the Phoenix light dome.

Mike

Very nice work on this Mike! I have always wanted to image that galaxy, just does not get very high here in Michigan. Might need to do a road trip to TX, NM, or AZ.

Thanks Pete. I'm hoping to get more data on this target before the monsoons start usually in July. Have to wait for the Moon to wane.....

Clear skies, Mike

So Someone suggested I try to make the stars more colorful...

crazy colors, I made a star mask to protect everything but the stars, and applied two Curves Saturation doses.

This stuff is fun!

Thanks Brian, it was a Bortle 4 site. My Astro Clubs dark site. About 50 miles east of downtown Phoenix. It's pretty dark to the east , north, south, to the west you can see the light pollution dome of the largest capital city n the U.S. Anything lower than 40 degrees is washed out.

Nice one elmiko :-) The reprocess did bring out the star colour more.

 

I'm not sure what your processing entailed, and forgive me if I'm telling you something you already know, but one thing worth trying is using ArcsinhStretch to do the stretch; I often find it gives me better star colour. Unfortunately ArcsinhStretch also has the effect of reducing local contrast, so I find it can be better to use the stars from Arcsinh and a normal Histogram Transformation for the galaxy. Worth having a play if you haven't already.

Lee, I have heard of that tool and I still have not used it. I Will definitely look into using it.

And that's why I post on this great site, so I can get tips from amazing Astrophotographers like you. I have seen your awesome images on Astrobin.... I really appreciate your input!

Clear skies and happy imaging, Mike

I look at M83 often with my xx14g, it's on my bucket list and now after your post it's come to the top of the list to snap and hang on the wall, thanks.

Thank you, Rick150, I wish you happy capturing! Make sure you post it when you complete it. Would like to see it!

I love your great image! Very well processed. I also felt that the stars are too neutral in color but with your rework it is a lot better and gives a more natural and rich feel to the image in my eyes.

Thanks so much for the reply. Yes , the stars are a little neutral, it could be because I only captured 1 hour of data.

I want to eventually get more data on this target.

Thanks, Mike
