Andromeda galaxy (M31) – first attempt

September 10, 2017 @ 11:13 By: gordon Category: Astronomy, Photography

I headed out yesterday evening to see what I could see. One of the things visible in the sky last night was the Andromeda Galaxy (M31). I put my camera on the back of the telescope and took a number of images. After aligning the images and working on them in Photoshop, I have an image where you can start to see some of the structure in the galaxy.

There’s specialized software for processing astrophotographs. For this image, I used one to figure out the image offset between the 8 images that went into it and then used Photoshop to manually align them. Then I converted the layers into a smart object, stacked them and applied some curves, exposure, level, and brightness/contrast adjustments.

For a first attempt, I’m happy with the results. I want to explore some of the other astrophotography software out there to see what works best for me.

Possibly the scariest tweet I’ve seen in a long time

There’s a lot of stuff on Twitter, some of it pretty scary and/or creepy. This tweet, however, probably jumps to the top of the holy-crap scary list:

I headed to Glendo State Park in Wyoming today to watch the eclipse with some friends. Here’s a quick photo of totality…

I shot this with my Tamron SP 500mm lens earlier this evening. With a bit of noise reduction in Lightroom, you can make out 4 of the moons.

It has been a while since I grumbled about the weather, so here goes:

-SHGSSNRA ??? Seriously? I had to go to the magic decoder to find out what that was:

LIGHT SNOW PELLET SHOWER
LIGHT SNOW SHOWER
LIGHT RAIN SHOWER

Geez… that’s piling a lot of crap into one element in a TAF. And we need exactly none of it.
