My family and I had the incredible opportunity to spend 6 weeks traveling around the western United States in "Harvey the RV".  My last name is Short, hence the title "The Long Short RV Trip."  wink.gif

Of course, a primary consideration for this trip was visiting some very dark skies during the two new moon periods during the trip, and I was not disappointed.  We visited dark sites in Nebraska (site of the Nebraska Star Party), Wyoming (Devil's Tower, Yellowstone), Arizona (Grand Canyon) and Utah (Zion NP, Bryce NP, Kodachrome State Park, Dead Horse Point SP, Natural Bridges National Monument).  The best skies I saw were at Natural Bridges where the SQM registered 21.89. The Milky Way was HUGE, stretched from horizon to horizon and looked twice as wide as I normally see.  We don't have skies like that in Indiana, that's for sure.  

 

I was able to collect data on 5 deep sky objects with my normal Telescoep/CCD/CMOS setup, and to a lesser extend Milky Way and circumpolar images with a DSLR.  It will take me some time to process the data.

 

First up is a rather faint, dusty area LBN552, LBN553 and LDN1228. This will probably be my least favorite image from the trip, but still I couldn't do this from home.

Love the star color in all your images Joel. What's your secret?

LOL, no big secret.  When stretching the color image I use HistogramTransformation and ArcsinhStretch and do several small stretches with each, alternating between HT and ArcsinhStretch.  ArcsinhStretch really brings out the color but using that tool alone really messes up the stars.  Then I just boost the color a little toward the end of processing.

I love dusty images, I never seem to get anything great when I try to shoot them from my home.   One day I'll make it out to a dark site with my main setup.

 

Great shot though!

Thanks Roberto.  I can't imagine trying to get this from a suburb location.  You are brave...I'll be interested to see how it turns out for you!

Good tip! I will try... Thanks!

That's a beautiful image of faint dust, Joel! I have given up on these targets from my suburban skies but they sure are pretty. The RV trip sounds like an awesome family trip; I look forward to seeing all the images.

I love the dust image, Joel.  And thanks from me as well for the tip on star colors. I'll give that a try.

Thanks Kevin, and you're welcome for the tip.  However it should be noted the every image is different and what works for one may not work for another.  Sometimes I simply use a more aggressive HistogramTransformation, sometimes I use MaskedStretch also. But ArcsinhStretch and HT does work well for many images.

Thanks Martin!  I've posted a total of 4 images from the trip and I'm working on #5 now.  #5 is the last deep sky image.  I have some Milky Way and circumpolar shots to process that I took with a DSLR but those won't be nearly as good since I'm not a DSLR guy....and it shows grin.gif
