Very nice, thank you.. I'd like to explore astrophotography at the right time. Is it an illusion or does the 2nd image form a spiral instead of circular? Did you use tools to add effects? I don't ever use any image editing tools but not sure if have/want to for astro.
Thanks! The trails aren't spiraling, just an effect of the distortion of the lens more than anything else. There is a lot I would like to do with astro photography that requires more equipment.

Nice pictures Isaac. Another forum I'm on has a photography thread and someone just posted a 2hr timelaps photo of the sky that is amazing. He as some explanation on how he photographs the sky without getting star trails or any movement out of anything it's all still and "everything" can be seen.
I've only ever done stills.. I like the simplicity and low cost.. but it would be good to explore time and motion if in special places such as Project Yosemite and prepared to buy and setup such as Dynamic Perception
I've been looking at those systems for a while. Very impressive results, but you have to pay to play. It is always a challenge to decide which components to invest in first.
the stars have a very quick 'apparent motion', of course as you know, it's the earth that's rotating instead so we need to counteract that by using a tracking mount.If you extend an imaginary line up from the earth's axis you have a point in the sky that seems to be stationary (the north and south celestial poles). By lining up the mount's axis to this point, all other points in the sky will be compensated for when you take a photo. In the north you have the star Polaris as your 'guiding' star and this is the closest star to the north celestial pole. In the south we're not so lucky so we need to find the south celestial pole using other methods. Once we have things setup we can take long exposures and not worry about star trailing. .
Ever wonder how to find the North star? Oh, besides using Ursa Major... Know your latitude, and raise that many degrees above the horizon, face north? Oh, that is more comlicated? Ever feel lost on the globe? Calculate your Latitude by measuring the degrees the North Star is above the horizon. Calculate your longitude is a little more calculated. If you have a working watch, noon set to GMT, or for that matter, to your home territory; and measure the highest point of the sun for the day. 1 Hour difference = 15 Degrees. Now you can tell people where you are when you are lost!You just need a watch, and know what your home longitude is
My step father has a few sextants left over from his sailing days. You guys could get together and navigate the world using stars.
I'm assuming that in the antenna photo he's facing NE. In the seashore photo he's facing due north. Earth's rotation during a timelapse photo of several minutes.
follow up to my story. Not my picture I repeat this is not my picture. the photographer said he took over 2hrs of exposure of the Rho Ophiuchus Nebula Complex and this is his result.
Wow! And, I'm sure your dad knows how to use those Sextants! I think it would be neat to have one, and know how to use it... and some rudimentary 2m band ULF capabilities, or know how to make it.
Step dad to be exact. He would love to show you how to use them....he loooves teaching people things. He tought me how they worked when I was like 8 years old but don't remember anything about them now. He also worked for the coast gaurd for awhile and even sailed with the captain of the Edmund Fitzgerald back in the day. He knows how to navigate like know one I know but has a GPS attached to his windshield ! just texted you also and 2m band ULF's are something I've never heard of but I'll bet there are more than a few guys over on the other forum where I got that astro photo from could explain how to build one seeing there are several electrical geniuses on that forum that offer help quite often.
Amazon had a one day sale last Friday on the Sony NEX-5T with 16-50 lens for $299 so I finally made the leap to a semi-fancy camera. http://www.amazon.com/Sony-NEX-5TL-Compact-Interchangeable-Digital/dp/B00ENZRP38/ref=sr_1_1?ie=UTF8&qid=1418138445&sr=8-1&keywords=sony+nex-5tl Have a lot of learning and practicing with setting aperture, ISO and f-stop but right out of the box the improvement in detail and most of all low-light performance is a BIG improvement over my Panny Lumix P&S. F-chat pic resizing will seriously degrade these but they're very sharp in native res (shooting in jpg not RAW).

Yeah a lot of people seemed thrilled with it for the $500+ selling price since it came out a little over a year ago. When I saw Gizmodo's article last friday afternoon about the $299 sale I couldn't say no. Was one of those "goldbox" deals. FYI you can use this site to get an alert if/when it goes below $300 again: Sony NEX-5TL Compact Interchangeable Lens Digital Camera with 16-50mm Power Zoom Lens | Amazon price tracker / tracking, Amazon price history charts, Amazon price watches, Amazon price drop alerts | camelcamelcamel.com Anyone else with a Sony NEX camera care to share any tips? I may get a decent prime lens and/or a bigger zoom one at some point, but for now the kit lens is fine for learning the basics. Have a price alert if the flash again dips below $130: Sony HVLF20S Flash for Sony Nex Series | Amazon price tracker / tracking, Amazon price history charts, Amazon price watches, Amazon price drop alerts | camelcamelcamel.com or the microphone goes below $65:Sony ECMSST1 Compact Stereo Microphone for NEX-3/NEX-5 Camera | Amazon price tracker / tracking, Amazon price history charts, Amazon price watches, Amazon price drop alerts | camelcamelcamel.com or this well reviewed 30mm lens again dips below $150: http://camelcamelcamel.com/Sigma-30mm-f2-8-Lens-Sony/product/B00BQXL5CM?context=tracker
