Deep Sky Image Processing in Photoshop

Well, this is it.  In this deep sky image processing tutorial, I'll be combining all of the data I was able to collect on the Orion Nebula this winter.  As we transition into Spring, a new array of deep-sky imaging targets will present themselves.  The winter astrophotography targets in the Orion constellation will have to wait another year to get photographed. Deep Sky Image Processing Processing Walkthrough - Orion Nebula with a DSLR The total amount of detail I was able to capture on M42 this winter was 3 Hours and 8 minutes of color RGB data.  I will be incorporating 2 hours a…

Manual Stacking in Photoshop for Reduced Noise

Even without a tracking mount, your astrophotography images can benefit from manual stacking in Photoshop.  This method involves aligning exposures and combining them into a master composite.  It can make a big impact on your astrophotos by reducing noise and improving the signal-to-noise ratio. [caption id="attachment_4045" align="aligncenter" width="713"] This night sky photo contains 11 exposures stacked manually in Photoshop[/caption] This technique requires no darks frames, no stacking software, and no tracking mount. The 2 software applications used in this tutorial are Adobe…

Screen Calibration for Astrophotography With my recent purchase of a new laptop computer, I am reminded of the importance of having a well calibrated computer monitor for editing and viewing astrophotos. The brightness of my new laptop screen is intense.  It appears to be about 25% brighter than my well-calibrated 23 Inch external IPS monitor.  This results in astrophotography images that are less-than pleasing to the eye.  I had to re-process many of my own photos in the photo gallery, once I discovered that they did not look the way I intended them to on different screens. Having a mo…
