Astrophotography

M42 Orion Nebula w/300mm f/4 - Only 30 minutes total integration time [12/23/2019]
Somewhat of an improvement over last March's version, which was my first astrophotograph.
M45 The Pleiades w/300mm f/4 + 1.4x TC (420mm f/5.6) - 1 hour total integration time [12/21/2019]
The brightest star cluster visible to us, it can be seen without the aid of binoculars or a telescope.
M33 Triangulum Galaxy w/600mm f/4 - 2 hours total integration time [12/23/2019]
I'm going to need a power outage covering a 5 mile radius around my house, on a moonless night, when there are no clouds, and I'm out in my driveway taking pictures, to get a good shot of one of these small galaxies.
IC1396 'Elephant Trunk Nebula' (H-alpha only) First Light with the Edge HD Schmidt-Cassegrain 8 inch telescope (configured at 1400mm f/7)
Schmidt-Cassegrain design is a hybrid reflector(mirror)/refractor(lens) design.
The Edge HD design goes a step further by flattening the focal plane, necessary for perfect focus all the way to the edge of the camera sensor.
Much higher power (5x more magnification than the lens used for the Heart Nebula above this one).
Technical junk follows: This image exposes each camera pixel to 0.5 arc-seconds of space, while the Heart image has a scale of 2.7 arc-seconds per pixel.
For perspective, one arc-second is about the width of a baseball... 10 miles away.
Another example: The tiny bright dot that is Venus (the 'Morning Star') averages about 30 arc-seconds.
The extra magnification comes at a cost of gathering less light (almost 4x less light) even while having nearly 50% more diameter.
It also makes tiny errors in tracking much more visible :(

Just in time for an anniversary present :)
