Our Bisbee wedding

We are working on a narrative for our wedding that took place on November 15th 2014. Stay tuned!

In the meantime, here are some of the beautiful photos that our good friend and photographer, Chris Summitt, took during the event.

Astrophotography by the Desert Museum

Lanna and I decided to do an astronomy event with some friends and family(Brek Thompson, Sean Bottai, America, Trevor Clark, Sam Hameroff, Michael Clark)  on October 25th by the Desert museum.

The weather, sunset and company were beautiful. Unfortunately the multitude of cars driving on Kinney road, on their way to and from Nightfall, presented some challenges for deep space astrophotography. Our setup was within 500feet of the road which lead to us receiving a great deal of unwanted light from passing cars and their high beams.

Despite the challenges of passing cars and some early scattered clouds we managed to get some pictures of a few objects. At first I was having technical difficulties with the Equatorial mount. Mostly balancing issues. Eventually we got the mount aligned properly and were taking pictures with Trevor Clark's camera piggybacked on the mount and my camera looking through the main scope.

NGC253, 10 x 90second exposures(cropped). We were ultimately limited by light pollution

Astrophotography on Kitt Peak

Saturday afternoon I went up to Kitt Peak National Observatory(the picnic area) to do some astrophotography. Dean Ketelsen was nice enough to invite me to join the Tucson astronomy club for their bi-annual "starbaque". For those of you who have never been up there, this was my first time, the observatory is a must see.

The new "unfinished" telescope/equatorial mount

Astrophotography with the 12" F/4 newtonian in Sierra Vista

Here are the first light images with the new telescope setup. The equatorial mount worked great. The polar scope made polar alignment quick and easy and I was able to obtain 90sec exposures with round stars right off the bat. Once I did a 1 star alignment the GOTO function was spot on, we used the sky view planetarium software in the SiTech software to slew the telescope around.

I tried using the Coma corrector, incorrectly, and ended up with some unflattering images. I pulled the corrector out for all the images seen on this page. The images here are all 60second single frames, no dark frame subtraction, no alteration except for cropping. The camera was at prime focus, ISO 800(accept for the moon shot).

Lanna's family was there and got to see the telescope "rig". Next time I will remember to take some pictures of everyone and the telescope setup.

We will hopefully be setting the telescope again on Kitt Peak this weekend. I will be trying out a new auto guider and the coma corrector in the correct configuration.

Camera tracking tests

On July 19th I set up the new equatorial mount right ascension axis for the first time. The goal was to test the tracking with a camera and 100mm lens. The photo's were taken in our backyard which is a 5minute drive from downtown tucson. As you would expect, the light pollution washes out the milky way, but fortunately I was able to prove the new mount is working extremely well. Polar alignment was roughly accomplished with a polar scope.

At first I was getting some very strange results. It turned out I didn't have the camera locked down on the swivel mount, whoops!

2 minute exposure, M8 the Lagoon nebula and M20 the Trifid Nebula are in the upper right. You can also see a Globular cluster in the far left of the field. Unfortunately this camera lens suffers from a great deal of Coma, which you can see in the comet shaped stars at the edges of the field.

Another photo of M8 and M20 more centered, this frame has been cropped.

5 Minute exposure of M17 the swan nebula and M16 the Eagle Nebula. You can see how washed out the image is due to the light pollution of downtown tucson. Note the pin point stars at the center of the frame, demonstrating the tracking is working great.

This is why you need a tracking mount. This is a 5minute exposure of Antares with the tracking turned off. Compare to the above images where there is no trailing in the images, even with a very rough polar alignment.
