Photos from Super Blood Moon Total Lunar Eclipse September 27, 2015

Here are my quick total lunar eclipse photos before I go to bed, I wanted to at least get something up from my DSLR and not just photos from my iPhone taking pics of the back of the display. Here are a few keepers, and a few that set the scene.

Eclipse sequence composite! The haze kinda messes up my layout, but it's still a nice collection in spite of the clouds.

You can see how, especially with a dim subject like the fully eclipsed moon, stacking layers to reduce noise really cleans things up! I havne't done that for all my eclipse phases yet, but I wanted to get some of these posted quickly. Also, the thin layer of clouds might make it a waste to try to mess with stacking when there is already haze covering everything.

The haze did make for some interesting features, compared to the typical straight forward eclipse photos you see online.

Things were off to a rough start, and I was worried I wouldn't get to see any of the eclipse. I even put my telescope back inside and just focused on my DSLR because I knew I wouldn't have a lot of leisure time to mess around. Single shot Canon T5i, ISO 800, 75mm, f/5.6, 4 sec

This gives you an idea of just how much haze was in the sky. I could see the disc of the moon, but would I be able to see the shadow of the eclipse at all? Single shot Canon T5i, ISO 100, 300mm, f/5.6, 1/3 sec

Pretty sure this is penumbral eclipse and not just a cloud. The moon was clear of any thick clouds, and was uniformly blocked by haze, so I believe the dimming on the left is the shadow from the Earth's penumbra. Single shot Canon T5i, ISO 100, 300mm, f/5.6, 1/400 sec

Clouds moving fast creating an interesting effect around the partially eclipsed moon. At 2 sec, I should have had more blur of the moon itself, but it turned out kinda neat. Single shot Canon T5i, ISO 100, 300mm, f/5.6, 2 sec

Partial eclipse with appropriately exposed lunar surface. Single shot Canon T5i, ISO 100, 300mm, f/5.6, 1/400 sec

More cloudy halo around the moon. Single shot Canon T5i, ISO 100, 300mm, f/5.6, 1 sec

Almost total, the moon was a tiny sliver in a bizarre shape it never makes on its own going through the regular phases. Single shot Canon T5i, ISO 800, 300mm, f/5.6, 1/2 sec

Total eclipse but still rather bright on the right side. Single shot Canon T5i, ISO 800, 300mm, f/5.6, 1.3 sec

Moon Test Shot Before Eclipse (Too Bright)

I wanted to make sure I had everything set up and tested before the highly anticipated lunar eclipse coming up on Sunday night. I went out and did a few quick shots of the waxing gibbous (77%) tonight, and did a quick stack. There is a purple halo around the brighter side of the moon, and I think my settings were a little too bright (shutter was too long at ISO 100).

Canon T5i: 20 frames stacked in Registax, each at 300mm, ISO 100, 1/200 sec, f/5.6

Clarity is pretty good though, and I didn't even do a High Pass layer on this one - just shoot and stack. I'll have to try a little faster shutter next time.

Shooting an eclipse isn't so much about planning in advance as it is about adjusting quickly (so I've found in my limited experience). The lighting changes quickly from a very bright full moon to a moon darker than the thinnest crescent.

Side note, I've been digging these Celestron countdown images on Instagram, check it out:

#MoonNight and Science Friday Shoutout

I got a shoutout from Science Friday on Twitter the other day! There is some buzz about International Observe the Moon Night (tonight, September 19, 2015), and Science Friday was looking back at their content from a segment I did on the air. I still remember that day, what a fun opportunity.

How do you take a great picture of the moon with your phone? Last year, @EricTeske gave us some tips. #SciFriLive pic.twitter.com/j2ndVu15sm

I replied with this photo (below) and a link to my article about taking even better moon photos with an iPhone by using video mode. I made the photo just for Twitter and it got quite a few retweets so I thought I'd also post it here.

Comparing a single frame of iPhone video to a stack of 115 frames taken from a 3 second AVI video file

I didn't realize until just now, but I've actually done some observing / photography on International Observe the Moon Night every time for the past 3 years - and usually just as a coincidence. Here are my posts from 2012, 2013, and 2014. Who knew I was being so inadvertently consistent!

For posterity, here is my moon photo from tonight, a combination of 20 frames each at f/8, 1/60 sec, ISO 100, 300mm. It's a little rushed, I'm not sure if that's why it's a little fuzzy or if it was the atmosphere. Blame it on the atmosphere!

Night Sky iPhone Photos with In-App Star Trails

I woke up last night to let the dog out and got distracted by the rising Winter Hexagon of stars. I can't wait to see this part of the sky on the regular later this winter. It's a particularly good target for iPhone night sky photos because the bright stars show up well even on the tiny iPhone camera.

I propped the iPhone up on a small stand (the same one I used here). The app I used is called Night Cap Pro and it does a great job!

Same photo as below, but I turned the brightness down a little bit to make the sky less pale gray and make the stars pop.

Same photo as above straight out of the iPhone, all star trails are done in-app with long exposure. This was about 10 minutes. That bright blob to the bottom left just coming over the roof is Venus, the rest is Orion, Gemini, and some planes.

I also used the star trail mode to make this image. The star trail mode actually does a better job than the noise reduction mode at cleaning up the sky for a nice regular star photo. This was about 20 seconds and you can just barely see trails.

I put the phone off the side of the table and pointed it straight up to see how it would do without light pollution on the horizon. I was so happy to see my favorite constellation Perseus and the instantly recognizable Pleiades cluster. So cool even on an iPhone photo! This one is also straight out of the camera.

My DSLR Moon Photo Workflow with Screenshots

Let's pick up assuming we already took the photos. Here I have 22 raw files loaded into iPhoto. I highlight the clear photos that look the best, and try to pick a clump that are right next to each other (less time between photos makes it easier to stack them later on).

Go to iPhoto > File > Reveal in Finder > Original File. We want to use the RAW files not the JPG files that iPhoto automatically makes to preview.

Select the RAW files in Finder and drag them to Photoshop CC.

Photoshop CC recognizes the RAW files and opens them in Camera RAW rather than the regular Photoshop window.

Select all of the images in the left hand column. We want to apply any changes we make to all of them not just the first one.

We are going to apply a crop just to cut down on the file size and make it easier to work with in Registax. We're just cutting out a lot of black background. Remember the moon is moving, so it's going to be in a different position in each image. Make sure you leave enough room in the crop for all of the different positions not just the first frame.

Apply the crop to all and save your images...

We're saving as TIFF files in a new folder on the flash drive (remember, I'm taking it back and forth between computers). Camera RAW will give the files sequential numbered file names.

It's applying the crop and saving each cropped file as a TIFF.

Our new batch of cropped TIFF files are visible in Finder. I'll take these on a flash drive to my PC laptop to stack in Registax.

 

I open Registax and select all my moon TIFF files.

I like to apply my own alignpoints rather than having the software guess. I don't use very many, and I hand pick spots with high contrast, such as craters, bright spots, or areas on the line between dark and light regions. I also stay away from the edges.

When you align, you are looking for the software to track parallel lines for each of your align points. If the green paths cross, it means something is wrong and it thinks one of your points is going a different direction from frame to frame compared to the others.

After I stack I go to the Wavelet tab to further refine the image. It's looking pretty good right? Just wait, the Wavelet tab is going to make a huge difference.

I play with the sliders on the left and watch my image sharpen and also add noise. This is a constant battle between increasing sharpness and increasing noise. You can't just crank it all the way up. Adjust to suit your personal taste. I personally don't like to go overboard, but just enhance the edges a bit.

click 'Do All' to apply the Wavelets to the entire image and then save your file. Again, I am saving as a TIFF so I don't lose any clarify to compression.

At this point I switch back to my Mac, taking my final stacked photo on a flash drive from my laptop.

I open my final stacked TIFF in Photoshop and duplicate the background layer into a new layer.

This becomes my High Pass layer. Even if you don't want to spend a lot of time processing each moon image, a High Pass layer is often worth while and doesn't take too long. To make it High Pass just go to Filter > Other > High Pass.

I usually go between 5 and 7 pixel radius for this High Pass filter, but you can play with different amounts.

Change the layer to an Overlay layer

And make the High Pass layer a mask, and select 'Hide All'

Now using a brush, coloring on the moon will reveal the High Pass layer. I use a wide blurry brush, and turn the flow rate down. See on the layer preview the white part is being cut through the mask.

If you didn't blur your brush, go ahead and add a blur filter to your layer. This will help blend the border between where you are using the High Pass layer and where you aren't. I usually stay away from the very edge, and focus on bringing out crater ridges.

Crop your final image down to however you want it.

Was it all worth it? Here is a frame straight out of the camera... and then...

Here is my final version, stacked, and edited with a High Pass layer. 22 frames stacked, each at 300mm, f/7.1, ISO 100, 1/250 sec. I also turned the saturation down because I wanted this one to be black and white. Sometimes a little color on the moon is nice, but again it's a personal preference each time.
