M42 - The Orion Nebula in HDR 01-Oct-2017






































M42 - The Orion Nebula in HDR 01-Oct-2017

High Dynamic Range Orion Nebula at various exposures, HDR combined using Aurora HDR 2018

Shot between 4:50 and 5:15am. The satellite tracks can be avoided by shooting earlier, or later, depending on the time of year.  At the time the images were taken, M42 was in line with the satellites.

Kinda cool, actually.

The Power of Post Processing

I've been toying with a variety of photo editing programs and in the following image, I really boosted the "clarity" (contrast) of an M31 image I recently posted, as seen here.

Admittedly a bit "grungy", or noisy if you prefer, but notice how much more detail is brought out around the galaxy's core, as well as the dust lanes.


The devil is in the details - and so are the data. :O)

(Adjusted in Topaz Studios /http://www.topazlabs.com/ )

A larger size of the above comparison can be seen here.

And here is a larger version of the new image.

Preparing for Solar Eclipse 2017 - White Balance Check

All digital cameras contain an IR (Infrared) filter in front of the chip, be they CCD or CMOS. By having the IR filter removed, the naturally occurring infrared produced by vegetation emerges. (A custom white balance is required to restore the color balance of non-IR emitting objects, such as the rocks in the background. I'm still working on that.)
Some astronomical objects, such as emission nebulae, also emit Hydrogen Alpha (Ha) and an IR modified camera picks up that signal more so than a standard camera. The photo on the right shows what the plant should look like, appropriately named a Blue Agave. Tequila anyone?

Preparing for Solar Eclipse 2017 - Sunspot AR2665



While preparing for the upcoming August 21st solar eclipse, Sunspot AR2665 was captured with the Nikon 300mm f/4 ED IF and Sigma 1.4x tele extender. Taken 15-Jul-2017, zenith is up. Reduced to 50% (i.e., 2x2 bin).
