MagAO-X 2020A Stay At Home Day 4: The Joy of Painting with Blog Ross

Hello, and thanks for joining me. Today marks the end of week three of self-isolation and quarantine for a lot of us here in Tucson. Based on what I have been seeing on social media and my own personal experience, a lot of us are starting to get a bit stir crazy from staying at home everyday. The self-isolation survival advice that I have heard the most is to try and cultivate a new hobby. For me, I have started playing Stardew Valley, a farming simulator game. A lot of hobbies however, require a lot more materials then a video game, making it frustrating and expensive to start up a new one. I thought I would share one of my oldest hobbies, painting. I may be Blog Ross, but I am no Bob Ross. Regardless I will try and step you through a simple painting, and give some advice on how to start painting using cheaper materials to keep the cost down.

A lot of us are missing astronomy and the great outdoors. Today I thought it would be nice to combine the two into a simple night sky in the desert painting. To give you a preview of what we will be painting today, here is my finished result.

To start, collect your materials.

For this painting I used five colors of acrylic paint: black, white, cadmium red hue, cadmium yellow hue, and cerulean blue hue.

My favorite brand of paint is Winsor & Newton Galeria Acylic. This is found in the Level 2: Artist section in Michaels. Almost all of my canvas, paints, and brushes are from this section. I have bought from their Level 3: professional level but couldn’t see a noticeable increase in quality to justify the steep increase in price. I do see a big increase in quality from the Level 1: Academic, and the price increase isn’t much between level 1 and 2 so I do suggest investing a little if you plan to continue painting.

Brushes: I used four of my go to brushes for this painting. A medium sized brush with a rounded tip, a small brush with a clean square edge, a fan brush, and a tiny detail brush.

Other materials: palette (a plastic TV dinner tray from the dollar store is a good alternative), and some water.

I used a canvas sheet that can be bought in a pad, as a cheaper alternative to a full canvas. I taped it to a board, and then drew some reference lines. I looked up some photos of saguaros for inspiration, and based the rock features off of Javelina Rocks at Saguaro National Park East.

To start painting we work from the background to the foreground. For our base color mix a Navy/dark-purple (2 parts blue, 1 part red, and a little black). Paint onto canvas using an up and down stroke, all the way to the rocks and around the saguaro. (I didn’t go all the way because I wanted to add a sunset effect that I decided later on was unnecessary and fixed that mistake). If you accidentally get some in your saguaro or rocks it is not a problem.

Looking at long exposure photos of the night sky, we see that it is not a uniform color. To add contrast mix 2 parts blue and 1 part red. Taking the medium size brush with the rounded edge, use a dabbing brush stroke over the background color. Don’t completely cover the background.

For some reason the photo makes this look purple, but it is actually pretty blue in real life.

With the leftover paint from the last step, add in a little bit of white (should be: 2 parts blue, 1 part red, a little white). Dab onto canvas again, concentrating the density to the band where you want the Milky Way to be.

To start making the Milky Way I mixed a lavender color ( 1 part white, with a little bit of equal parts blue and red). I used a back and forth brush stroke to make a line/ steak effect. You could probably continue dabbing the color on if you like that look more. Put this color over where you want the Milky Way to be. Over the lighter color you just laid down, add some darker color for the dust lanes in the Milky Way. I used dark purple (1 part red, 1 part blue, a little black), but dark blue would work too.

Now I took my smaller brush with the square edge and white paint, and added highlights and small dust clouds to my Milky Way. I used both small dabbing brush strokes, and some half-circle brush stokes. There is a bright bulge in the Milky Way that faces towards the ground. Decide where you want the bulge and concentrate more white in that area. There is a second smaller bulge on the opposite side at that location. If you go too wild with the white (like I did) go back in with your dark purple or blue and add back in some dust lanes.

Looking at photos of the Milky Way, near the bulge the color is more yellow and less white. Mix a very light yellow (1 part white, a little yellow), and add in some yellow to your light spots. I used my fine detail brush to do this. I then went back over the edges of the yellow parts I put down with some white, to blend the colors a little better. I used a dabbing brush stroke for this.

Once you are happy with how your Milky Way looks (maybe adding in more dust lanes, maybe more bright spots) its time to add stars! Mix white paint with water (something like 2 parts water, 1 part white). Mix it well so that there are no clumps, should look like milk. Take the fan brush, or any large, flat brush and using your fingers flick the hairs of the brush to create the stars. If this explanation is confusing you can find a tutorial on YouTube. Do this until you are satisfied. I found that this made a lot of really small stars, so I took my small fine detail brush and added in some larger stars concentrating them in the Milky Way. I added a lot of these white stars into the brighter areas of the Milky Way.

As we know from astronomy stars aren’t all the same color, so lets give the white stars some friends. Mix some light blue (1 part white, a little blue), and using the fine detail brush add in some blue stars. Concentrate these outside of the Milky Way. I even added 2 or 3 red stars.

unlike us the stars are not self isolating so give them lots of friends

At this point my painting looks like the image below. (Noticed I fixed that mistake I made earlier. Acylic is great for beginners because it is very forgiving).

Now it is time to paint in the rocks and the saguaro! Take black paint and the small brush with the clean square edge and fill in the saguaro and rocks with black. I decided to mix a little bit of blue into the black for one of the rocks, so it would look like one rock is in the foreground, and the other in the background.

Now wait for the painting to dry, then add in your signature and it is done!

And don’t forget the important last step, give the painting to a friend who is struggling with isolation :). (While maintaining proper social distancing guidelines.)

Happy painting,

Here is a relaxing song to paint to for the song of the day.

The MagAO-X Migration

To beat the harsh Canadian frost, most birds migrate south for the winter. In Tucson we have the opposite problem! As temperatures rose in the desert a group of us (Jared, Alex R., Kyle, Laird, and Lauren with alumna Kelsey Miller meeting us from Leiden) headed to Canada to beat the heat and present our research at Adaptive Optics for Extremely Large Telescopes 6 in Quebec Canada.

Sunset on the first day of Quebec City

Some of us were a bit thrown off from the sudden transition from English to French, but for me who just got back from Marseille, it was interesting to see the differences between Canadian French and Parisian French. One thing that was definitely the same was the amazing French cooking. The MagAO-X students had a truly memorable night with alumna Kelsey Miller, who took us to a gastronomy restaurant well above the grad student paygrade. $20 and five thin potato slices later the hungry grad students ended up at a French Canadian Irish Pub (does that make sense?) just in time to grab some real food and watch the Stanley cup finals.

Speaking of memorable dinners, the conference dinner was the best I’ve ever been too! Really good food followed by an incredible musical group. They could play any song on the spot on their classical instruments, and spiced things up with acrobatic displays (never missing a note!). Our very own Kyle Van Gorkom was even lucky enough to be chosen as an audience volunteer! They projected his face onto a screen for a very silly comedic dance.

But things weren’t all fun and games for the MagAO-X crew. We were all hard at working presenting our current results and building anticipation for our first light run. In order of presentation …

Lauren presenting her work on three-sided pyramid wavefront sensing.
Kyle presenting his mad skills at deformable mirror flattening.
Alex Rodack presenting his work on simulating the Real Time Frazin Algorithm that uses knowledge of your system to improve contrast through your coronagraph.
To finish out the conference P.I. Jared Males presents current MagAO-X progress and his vision for an extreme adaptive optics system on the Giant Magellan Telescope. We were all relieved that his presentation didn’t crash this time.

(Kelsey and Laird also had posters but we were bad students and didn’t take photos….)

We are all back in Tucson now, but I for one am missing the lovely weather. At least I have my heap of maple flavored snacks to remind me of cooler temperatures and a great trip. Although we didn’t see any Canadian Geese this trip, they are this post’s song of the day.

2016B Day 9: The Odyssey

Commissioning is a long and windy road, not unlike Odysseus’ journey in the Odyssey. The MagAO team has traveled half way around the world, and have had our share of battling monsters (like our deformable mirror!), and treasure hunts (to spot that elusive green flash!). We are so close to the end of our journey, only two more days and we should be on sky!


Speaking of mythical creatures…. Professor Laird Close caught this awesome shot of a viscacha mid hop.

As you can imagine things are getting busier than ever as we ramp up to go on sky. Here is a video of Dr. Katie Morzinski preparing the CLIO infrared camera for the telescope! She is filling the dewar with liquid nitrogen to cool it 55K! Watching her made us wish we had the stuff to make Dip N Dots…

The wavefront sensor dynamic duo finally achieved a pupil separation of 40 pixels!

The rest of the AO team has been hard at work getting the deformable secondary up and running! But I don’t have any pictures sorry guys.

… And take an obligatory selfie of course!

Song of the day is both space and Odyssey themed!
