Jupiter Shadow Transit Animation with iPhone

23 Apr

This week I assembled my first-ever animation of a planet photographed with my iPhone. On April 14, 2015, I took images of Jupiter over the span of 2.5 hours with an iPhone 6 attached to my 8″ Celestron NexStar 8SE telescope. I then chose the best four images and assembled them into the following GIF:

Jupiter Shadow Transit AnimationWhat you’re seeing is the shadow of Jupiter’s moon Ganymede move across Jupiter, while Jupiter’s rotation carries the Great Red Spot along. Ganymede itself is visible at left in the first three frames before it moves out of view.

I was able to use my iPhone for almost everything required to create this animation except the stacking and editing of the individual images. To obtain and edit the images with my iPhone, I used the methodology outlined in my smartphone astrophotography post. To create the GIF, I used the 5SecondsApp.

I would love the ability to stack and edit video directly via the iPhone, so if anyone knows of an app to do this (or wants to create one) please let me know in the comments!

Lastly, if you want to enjoy this with some relevant music, see my Instagram version.

My iPhone Astrophoto Process Featured in ShinyShiny

2 Apr

I wrote a guest post for ShinyShiny that can serve as a very quick “how-to” for photographing the night sky with an iPhone (or any smartphone, really.) I was really happy with the way they used my imagery and hope this inspires some new people to try their hand at smartphone astrophotography!

Jupiter with iPhone, February 27, 2015

2 Mar

I captured my best iPhone image of Jupiter to date thanks to excellent seeing and a new 9mm eyepiece. The Great Red Spot is clearly visible as is the moon Io at far left.

I also took some video with my iPhone 6. The default iPhone 6 camera does not seem to capture the colour of small objects properly (I’ve yet been able to match the planetary quality I obtain with my 4S) but I was able to capture a decent video of Jupiter and 3 moons a bit later that night using the FilMicPro app:

My first telescopic photo with my new iPhone 6 was a success! Here’s the Moon on November 28th through my 8″ telescope, taken and edited solely with the iPhone. It’s had more than 17,000 views on Flickr so far!


Help Send a Rover to Mars!

Crowdfunding its Way To Mars:
The Northern Light Mission

This mission needs YOUR help! A Canadian group is looking to launch a compact lander and micro rover to Mars in 2018 and is relying heavily on crowdfunding to do so.

Here are some of the details listed on the Northern Light IndieGogo page:

“Led by Dr. Ben Quine, a professor of space engineering at York University, and Canadian space company Thoth Technology, the team has been developing the Northern Light mission to explore Mars.”

“In space, small is beautiful, and Northern Light is small. The complete entry, descent and landing system, lander, micro-rover and science payload have a combined mass of just 75 kg.”

The mission would include a mini rover to explore the surface:

Beaver Rover Prototype

“With a mass of approximately 6 kg, the Beaver rover will be used for geological surface exploration. Beaver will operate under its own power and will have a range of 1 km. The rover will be equipped with a visible camera for maneuvering and surface exploration, as well as an Argus spectrometer for mineral classification. This is the little rover that could.”

The robots would hitch a ride on a spacecraft already heading to Mars – potentially the Russian-European Space Agency ExoMars rover mission or a future Indian Space Research Organization (ISRO) mission – and would be small but oh so cool!

The group is looking to raise $1.3 million by January 3, 2015 and has set up an IndieGogo page to do so: https://www.indiegogo.com/projects/northern-light-mission-to-mars In addition to receiving swag, those who donate also get the opportunity to vote for the lander’s potential landing site.

Check out the IndieGogo page for more details and help this project out if you can!



Mars From Earth vs From Orbit

30 Sep

India’s Mars Orbiter Mission (MOM) successfully entered Martian orbit on September 24, 2014 and has sent back some spectacular photos. The most recent (and most beautiful, IMHO) is a global, colour image of Mars that shows Syrtis Major and the Hellas basin at far right.

After seeing the image, I realized that I’d taken a photo of almost exactly that region through my telescope in April. I’ve compared the two below. Clearly, it pays to be in orbit!

The Five Ancient Planets…with an iPhone!

7 Jul

Since 2012, I’ve been using an iPhone 4S to photograph the planets and the Sun via techniques described in my iPhone astrophotography blog post. By attaching my phone to my 8″ Schmidt-Cassegrain telescope (for planetary photography) and my 40mm solar telescope (for solar photography) I’ve been able to capture some surprisingly detailed photos of our celestial neighbours.

It was only this year, however, that I was able to capture Mercury (the most elusive of the naked eye planets) through the telescope. With Mercury in hand, I was able to complete my first collage of the Sun and the five planets known to the ancients: Mercury, Venus, Mars, Jupiter, and Saturn.

Moving Forward

Now that I’ve completed this collage, I plan to attempt to capture Uranus and Neptune with my iPhone this summer/fall to create a complete montage of the solar system. Those will be very dim targets and I’m not sure how well I can capture them via the iPhone camera, but I figure it’s worth a try!


All photos were taken with my iPhone 4S through my Celestron NexStar 8SE telescope unless otherwise noted.
