It’s the last day of May already. Every year, time accelerates and the years fly by. May was an eventful month. We started the month by celebrating our anniversary on Cinco de Mayo at Baja Joe’s. We ended the month by celebrating Donna’s birthday on Memorial Day weekend with dinner at Alessia’s Ristorante Italiano. We love that place!

We had our first housesitting “job” through Trusted Housesitters. We drove down to a home southwest of Tucson, Arizona. It was in a neighborhood of custom homes on large lots south of the area called Tucson Estates. It was a very nice house with a pool and jacuzzi.

The job included taking care of two dogs – one was a big, one-year-old labrador named Rebel and the other a little chihuahua called Lil Bit. The lab was pretty rambunctious, although he would settle down after a bit and would sit on command. We knew that part of the deal was allowing the dogs to sleep with us in the master bedroom, but it was too much for me. So Donna slept with the dogs while I retired to the guest room. The dogs really only required a minimum of care – give them treats, feed them at their scheduled times and clean the yard after them. There was also a tortoise named Diego, but he was still hibernating so we didn’t see him.

We treated the week as a mini-vacation. We dined out for dinner with a friend in Tucson, Kathleen Wessels and her mother Sandy. We had lunch at Tiny’s and another lunch at the Coyote Pause Cafe. We also had a great breakfast at Coyote Pause – we really like that cafe. We enjoyed the Arizona Sonoran Desert Museum one morning, which was less than 10 miles away. The museum is more like a zoo for native animals and botanical garden. We spent about two hours hiking through the property.

I could add pages of pictures from the museum – but I won’t. I think I’ll back pedal a bit to some earlier events in May. On the second week of May, I made three trips to the Weaver’s Needle Viewpoint to capture images of the Pinwheel Galaxy (M101). I ended up processing 161 sub-exposures for a total integration time of 3 hours 21 minutes.

This galaxy is 25 million light years away from earth. Donna asked me to put a light year into context – she asked me how far is the moon in light years. Well, the moon on average is about 220,000 miles from earth. Light travels 186,000 miles per second, so the moon is less than 1.2 light seconds from earth! The sun is about 8 light minutes from earth.

The interesting thing is, eight days after I completed my image of M101, one of the stars in a spiral arm of the galaxy exploded into a supernova. This was first seen by an amateur astronomer in Japan. The supernova marks the end of life of a star as it explodes into intense heat and light. The bright star can be seen in photos taken after May 19th – although the actual event occurred 25 million years ago. I don’t know how long this star will burn so brightly – it may be weeks or months.

I packed my astronomy gear for the trip to housesit in Tucson. The sky would be dark in the area we were going to. I took my big APM 140-980 telescope.

I set up my telescope and mount in front of the house. The really nice part was, I only had to remove the telescope and store it, I could leave the mount set up where it was for next four nights.

I wanted to try capturing an image of something new while we were there. I targeted a globular cluster in the constellation Hercules called M13. Globular clusters are gravitationally bound, stable groups of tens of thousands stars. They are a real challenge for newby astrophotographers.

Over three nights, I was able to get 365 usable sub-exposures for a total time of 6 hours five minutes. I’m pleased with the results.

M13 contains over 100,000 stars and is one of the brightest globular clusters in the northern hemisphere. It’s roughly 25 thousand light years away from earth.

I had one maintenance chore at home earlier this month. We cool the Arizona room with a swamp cooler. The cool air circulates to the front of the house providing some moisture and lowers the workload on our air conditioner.

One morning, I realized it wasn’t blowing cold air – it was pulling ambient air from outside. After a quick inspection and a couple of tests, I determined the water pump was shot.

There’s a store that carries swamp coolers and parts about a mile away from Viewpoint. I found a replacement pump for $35 and installed it. But it’s never that easy, is it? While I was connecting the pump to the water distribution pipe, the plastic fitting broke. The threaded portion of the fitting was stuck inside the distribution manifold. After a few attempts with various tools, I managed to extract it. I made another run to the shop and found a replacement fitting.

I put everything back together, and then the drive belt for the squirrel cage fan went kaput! One more trip to the shop for a belt and all is good now. The cooler is blowing cold air and it only cost me $45 in parts and three trips to the shop – about two hours for what should have been less than half an hour total!

Donna made a couple of new chicken dishes. The first is a skillet dish called Chicken Afritada with potatoes, carrots, celery, peas and Castelvetrano olives.

Last night, she made seared Duroc pork chops with a side of calabacitas, which she saw on the menu at Coyote Pause. It was delicious.

The weather down in Tucson was similar to the daytime temperatures here in Mesa. The nights were cooler though. For the month of May, we’ve had highs ranging from the mid-80s to high 90s. We had 100 degrees on just one day. This is cooler than this time last year. The next two weeks are forecast to be more of the same – mid to high 90s for daytime highs with overnight lows in the high 60s. I won’t complain about that!
