The other photo I got of the One Tree Hill Lookout Tower under the Milky Way from a few nights back
ISO 5000 | 25 sec | f/2.8 | 7mm
Another shot made during this August astrocamp, this time is the area around NGC7635 (the bubble nebula) in RGB+Ha.
The RGB comes straight from the astrocamp and is about 50:50:50min of exposure, the Ha component has been acquired at home, in the middle of the town (with a very high degree of light pollution...) using 5nm Ha filter and consist of about 60min of exposure. The camera orientation between the shots was not the same.
Gear used was a Takahashi Epsilon 210 f3 on Astorphysics Match1 GTO mount. CCD camera was a QSI 683 WSG8 with Astrodon gen 2 filters guided by a Starlight Xpress Lodestar camera.
Thanks for stopping by!

Sometimes astronomers use their highly stretched imagination to conjure something that looks a bit like the nebula they've been photographing for longer than their wives care to try to calculate. This nebula is not one of those. It is the result of the powerful winds emanating from the brilliant Wolf-Rayet star inside the almost perfectly spherical bubble it has blown. This is 13.6 hours of imaging in the light of Hydrogen, Oxygen, and Sulfur.

It has been exactly a year since I first got my foot in the door of astrophotography, and since then, I dove headfirst into this hobby. I had no idea that I'd ever become this obsessed with something before. Here is my first Milky Way Capture of 2017 with many more to come.
For this one, I traveled out to Enchanted Rock State Natural Area (my favorite place to shoot astro while a student at UT Austin. I'll be graduating and moving this May so I want to make the most of the area's dark skies). The clouds were nasty this night, and we waited it out for 45 minutes before getting a small 20 minute window to shoot before the damn clouds covered the sky for the rest of the night. We were scrambling to get our gear up and running so I had time to do a very rough alignment but it worked for the most part. The coma on this lens is pretty bad unless you stop down to f/4 which I decided not to do given how little time I had to get up and running. Either way, I'm very pleased with the result and have found a new processing method for my widefield Milky Way shots! I'm very pleased with how the dust lanes are much more visible in this shot as well as the Rho Ophiuchi Cloud Complex. I've learned so much over the past year and there is much more to come! Next time, hopefully I'll get more integration time so I can set up and take 3 or 4 minute exposures for more detail.

8 shots at ISO 800, f/2.8, and 60 seconds. Stacked and processed in Photoshop with minor edits in Lightroom. Thanks for looking!
Taken around 2am on February 14th with a Celestron C6 SCT, Celestron AVX mount, 2x Barlow, and ASI120MC. Captured with SharpCap, stacked with AutoStakkert, and processed with Astra Image Pro and Photoshop.
Canon EOS 100D, Sigma DC ART 30mm f1.4, and Hoya Red intensifier filter; 12 exposures of 10s each stiched to pano with Lightroom.
I guess it is about time I learn to work with DSS for better detail and less noise, and GIMP for foreground blending to take the milkyway images to a higher level... :-)

M 45, also known as The Pleiades or Seven Sisters, is a bright open cluster in the constellation Taurus. Comprising mostly luminous, hot blue stars, the surrounding nebulosity is thought to be an interstellar dust cloud between us and the cluster. M 45 is easily seen naked eye, and under dark skies the blue nebulosity is apparent.
This image is the first of our 2018-2019 season at SC Observatory. more than 1,200 two-minute subexposures, totaling almost 42 hours, were taken over three nights using our 4-scope wide field array. The array is controlled using a custom multi-scope version of Voyager software. Image processing in PixInsight and Photoshop.
Imaged and processed in Samphran, Thailand by the SC Observatory team: Mike Selby, Andy Chatman and Stefan Schmidt.
This is not a fake image. Just stacked & processed. You can read more about how it was created on my website: 29a.ch/2017/06/22/urban-astrophotography
Enjoy.
