Astrophotography Timelapse - My First Night Out

www.learningdslrvideo.com I have always been a sucker for really well done astro timelapse from people like Tom Lowe, TSO Photography and Randy Halverson. This past weekend I drove up into the mountains for a camping weekend with my oldest daughter. Every so often my wife and I like to split up our girls so we can get some one on one time with each girl. I knew we would get a chance to talk and tell ghost stories around the campfire. My photography goal for this trip was to try my first time lapse of the stars, I had ideas of grandeur of quality equal to Tom Lowe and others, and I was even more excited to try after I watched Tom Guilmette's awesome BTS video about Timefest. When I packed up the car in the morning there was not a cloud in the sky, however as we drove up to RMNP the clouds started forming. The previous weekend with my other daughter I got rain out at night and didn't want a repeat performance from Mother nature. By the time we setup up camp it started to drizzle. It rained on our hike but after that the clouds started to break up giving me some hope that we would have a clear night sky. Long's Peak The object of the timelapse was Long's Peak. Years ago I climbed this 14256' mountain with a friend in what turned out to be the nasty night camping ever, instead of starting out at 2am to start the hike with a day pack and head lamp on, my friend and I decided to take heavy packs in the afternoon and camp in the boulder field just below the sharp cliffs you see ...

Astrophotography DSLR Cameras - How to use the shutter speed until you

Now that you understand a bit 'light, you will have to do a little' to understand your camera. The best way to do this is to look up from your Handy Dandy help or instructions, which should also help some graphics to help you. The other way is more common, and that the careful practice of finding the right settings for "hitting buttons until you find it." With the cameras, this is difficult because often defined not clear how people with this methodwants.

If you find it all:

DSLR

You want to set the camera in manual exposure or simple cameras, set "night mode". Then you need the lens to its maximum aperture, which is usually set to 2.8. Set the ISO to the highest level you have (400 for the simple point and shoot cameras). Focus

Focus is the next topic which must be faced by using the Handy Dandy Guide or the method of "hitting the buttons until you find" it. Discover how to turn off auto-focus settings and then manually focus the camera on infinity, or as far away from that to focus the camera. With a simple point and shoot digital camera, this could mean for the small icon with a mountain. For the DSLR at some point during the day, focus your camera on something really far away, and then turn off the autofocus. If your digital SLR camera has an adjustable lens manually focused to infinity andTape. Experiment with this day, not only the confidence of the settings. Try to take something away from the job setup. White Balance

The next argument is to master the white balance settings. This is a way to compensate for red skies polluted by light, using the auto white balance. Most cameras auto white balance can be preset. These default settings usually give poor results at night. This is especially a problem whenshooting anywhere that has light pollution. It makes the sky a brown/red color. Some cameras have a way for the user to select the white balance. ( check out the manual or hit buttons). Whichever way, you want to set the white balance to Tungsten when using long exposures when photographing the night sky. This will give a nicer sky background There are some high-end cameras let you use a custom white balance. If so, try adjusting the blue/amber and magenta/green balance.

Part 1, Astrophotography Processing in Photoshop - Stretching

This is the first video of a 5 part series I put together on my methods of stretching, color correcting, and curves adjusting my astro-photographs. View some of my work here: www.slas.us I have learned many of these techniques from various places online, and from tips from very good DSLR astrophotographers. I will not say these are the best methods for processing astro photos, and any tips are welcome. These methods have worked best for me, and I am always learning new tricks. This is two photos of M42, the Great Orion Nebula. Image Info : Shot the night of 11.25.09 from Southern UT Image Info: Scope : Orion 10" F4.7 OTA Camera : Canon Rebel XSi, (Self Modified) Corrector : Baader MPCC Mount : Orion Atlas EQ-G (EQMOD) Images : 18 Lights @ 180sec ISO 800 - 12 Lights @ 10sec ISO 800 (core data) 9 Darks 10 Bias Software : Subtraction in Iris, Registration stacking in Registar If you not sure what any of the above means, google it :) I plan on doing another series as well that goes over the basics of astrophotography, how to aquire the shots, the equipment needed, and how to get them ready for processing. This series is mainly for people who have already stacked an image, and are looking for good methods to stretch and process it for the final result. In This Video: I start with two photos, the first is a series of photos stacked to bring out the fainter part of the nebulae, the second is a series stacked to bring out the bright core. This video will show how I go about the ...
