We’ve come through one of the coldest, wettest winters in memory here in Arizona. Donna’s vegetable garden seemed almost dormant at times as the vegetables endured cold nights. Things finally took off near the end of February and she harvested earlier this month.

She replanted for her second crop, which we expect will grow much faster as we are enjoying warmer weather and longer days.

She relocated the worm bin when she replanted. The worms are thriving and continue to multiply. The same goes for my second worm colony.

The highlight of the year came on Wednesday, March 15th, when my youngest daughter, Shauna and her husband Gabe came to visit from Bermuda. Of course they had our youngest granddaughter Petra in tow. We picked them up at the airport and they visited while we had snacks and a drink. We met our granddaughter for the first time. We hadn’t visited Bermuda since the COVID lockdown.

Later, I dropped them off at a nearby AirBnb. On Thursday morning, I picked them up again and we drove to west Mesa where Shauna had rented a car through Turo. She picked up a new VW Taos compact SUV. She said the car felt big to her – Bermuda doesn’t have many (any?) full-size cars. Everything is sub-compact there. It’s an island after all with narrow roads.

We came back to Viewpoint and gave them a tour of the grounds. We finished the tour at Fat Willy’s where we enjoyed lunch on the patio. Lucky for us, we claimed a table next to a propane heater – it was a bit chilly with the breeze. I mentioned the unusually cool weather – when they arrived on Wednesday, it was raining and we had a high of just 65 degrees. Thursday was only slightly warmer with a high of 69 degrees.

Thursday afternoon, they headed west to visit with Shauna’s mother and stepfather in Wickenburg. My oldest daughter Alana and her husband Kevin were already there. They flew down from Washington to meet up with Shauna and Gabe.

Alana and Kevin will come here this afternoon and we’re planning to go out for sushi tonight. Shauna and family will come back to Scottsdale on Monday. They’re meeting friends and will attend a spring training MLB game Monday night. Donna and I will babysit Petra while they’re at the game.

I need to shift gears now and discuss my latest passion – astronomy and, more specifically, astrophotography. When the astronomy bug bit, I spent the first month or so looking at the moon and planets visually through my telescope. Then I decided I wanted to capture the images, not just gaze through an eyepiece. I started with the easiest target – the moon. Then I spent about three months working on Jupiter and Saturn.

Once I had the planetary imaging techniques figured out, I wanted to try my hand at deep sky objects (DSO). I don’t mean to imply that I mastered planetary imaging – far from it. But here’s the thing. Astronomy has seasons – who knew? We are past the optimum time for imaging planets now. The moon is available year ’round except for about a week or so out of every four weeks when it crosses the sky during daylight hours.

The winter is the time of year when nebula imaging hits its stride. Nebulae generally are invisible to the naked eye, but if you know where to point your telescope, they can be found and images can be recorded. The difficulty arises from the distance involved and the dim light they produce.

Our eyes see in real time – that is, whatever photons strike the rods and cones in our eyes are immediately transferred to our brain. A sensor in a digital camera can be used that way or it can be exposed to a particular light source for a longer time and accumulate the light photons, gradually making the resultant image brighter up to a point. It gets tricky when we are talking about deep sky objects that have a wide spectrum of colors and brightness.

Keeping the camera sensor on point for long periods of time requires accurate tracking. The earth is in constant motion. As it rotates, the celestial bodies appear to move across the sky. Modern astrophotography utilizes powerful software and carefully designed telescope mounts to track the object we want to capture.

There’s also the fact that the earth revolves around the sun. Remember, I said astronomy has seasons? That’s why. As the earth reaches different points in the elliptical path around the sun, different parts of our solar system and the universe are in view. The second quarter of the year is known as galaxy season. The earth reaches a point where most of the Milky Way is no longer visible in the night sky, opening up paths to distant galaxies. The summer is planet season. Then we return to nebula time.

Astrophotography, especially DSO astrophotography, is a very difficult hobby. It’s probably one of the most challenging hobbies I’ve encountered. Having said that, I love it. I’m learning so much. There are so many decisions regarding gear, software and which objects to target. There are no absolutes – that is, there’s more than one way to approach the hobby. An inexperienced amateur astronomer will require a few years to really grasp what they need and what works best for them.

My gear is evolving and I found that I need different software for DSO than what I needed for planetary imaging. Like I said, there’s much to learn. I’ve taken up the DSO challenge and I’ve captured a few objects. My first was late in January when I shot an image of the Andromeda Galaxy. In hindsight, it was a marginal effort. I then went after the Pleiades star cluster. I made some improvements there after a few attempts.

At the end of February I tried to capture the Orion Nebula and was moderately successful.

This led me to the Horsehead Nebula.

My final version of the Horsehead came from two sessions. First on March 3rd, I captured 46 sub-exposures of 120 seconds each from our backyard here at Viewpoint. Then, on March 12th, I captured another 44 subs of of 90 seconds each from darker skies at the Weaver’s Needle Viewpoint. I learned how to combine the data collected from the two sessions in AstroPixelProcessor and the result is the image above.

My latest attempt came from our backyard and it’s the Rosette Nebula.

The Rosette Nebula is 5,200 light years away from earth. It’s in the constellation Orion as are the Horsehead and of course the Orion Nebula.

I’ve arranged an outreach event next week for our astronomy club, East Valley Astronomy Club, here at Viewpoint. Members of the club will show up on Wednesday evening and I’ve secured permission to set up on the ball field at the north end of the Viewpoint complex. We’re inviting people to come out and look at the sky through our telescopes.

Yesterday was St. Patrick’s Day. Of course, everyone in the park was Irish for a day. I cleaned up Midget-San – it’s amazing how much dust finds its way under the car cover. I’ve had its battery on a float charger and the gas in the tank was stabilized, so I was confident about it running after spending many months stored on jack stands.

It fired up without any issues! We joined the St. Patrick’s Day parade in it. Donna threw candy to the people lining the streets of Viewpoint and made sure she found kids to toss the candy to. It was fun.

There was a car show after the parade. I didn’t enter Midget-San because I didn’t want to commit to hanging around all day. I’ve done the car show thing with my old Corvettes in the past and I’m not up to entering anymore. But I like to look around!

Last night, our friends Chuck and Sue Lines came over and joined us for happy hour and dinner. Donna made her usual traditional St. Patrick’s Day dinner of corned beef, cabbage and carrots, champ potatoes and Irish soda bread. And Sue brought a grasshopper pie she made. We had a great time – good food and conversation with good friends. It doesn’t get any better.

As always, Donna keeps fresh cooked, nutritious, delicious meals on our dinner table. Here are few examples from the last couple of weeks. I’ll start with a batch of grilled chicken with tomatoes and corn.

For another meal, she prepared braised chicken thighs and peppers over creamy polenta.

The next dish was very tasty. It’s garlic butter flank steak pan fried with baby potatoes and fresh herbs. Yummy!

The weather has been much better in the last week, but it looks like we might have a wet, cold snap for a couple of days next week. I hope Wednesday is fair for the event with the astronomy club.
