Arizona Worm Farm

I guess Donna wasn’t busy enough with her activities which include Tennis Club, Pickleball Club, golf, Viewpoint Concert Band and her work providing dog walking and companion care for some elderly residents here at Viewpoint Golf Resort. So, she took up another hobby.

She built a raised garden bed from a kit made by a company called Vego. She did most of the work herself with only a little assistance from me. She used quarter-inch mesh screen to line the bottom of the bed – this will prevent critters like gophers or moles from entering the bed. The she filled the bottom with garden waste – broken branches, leaves and other plant matter. This was mainly just filler to take up space without spending money on soil.

From there, she needed a higher quality garden mix to provide the proper consistency and mix of nutrients for her plants. For that, she bought some garden mix from Home Depot and then wanted to improve upon that. I found a place in south Phoenix called Arizona Worm Farm that was just the ticket.

Arizona Worm Farm is an interesting place and a great story of entrepreneurship. About five years ago a guy named Zack Brooks bought ten acres of land that was formerly a cotton field. He had a vision of running a farm that would be a zero-waste, self-sustaining enterprise that would provide sustenance for up to 10 families. That grew into a successful worm production facility that creates compost and soil enriched with worm castings as well as fruits and vegetables.

He developed relationships with various businesses that had a need to dispose of organic waste material. He gets wood chips from landscapers that would otherwise get sent to landfills. He gets vegetables that are past their sell-by date that would normally be thrown out as garbage. He also gets things like melon rinds, carrot tops and other vegetable matter from companies that process vegetables into pre-cut vegetable packages. Finally, he has sources for horse manure from reputable stables that only feed pesticide- and herbicide-free material to their horses. He raises chickens and uses chicken manure as well.

The materials are combined and used as feed for worms, which in turn, provide the worm castings – a polite term for worm poop. This is a very nutrient-rich plant food. He sells about 60,000 worms locally to gardeners per week as well. We went to the worm farm on a Saturday morning to take a class called Gardening 101 which was led by the garden manager and head grower, Leslie. It was 90 minutes well-spent. Donna took copious notes. The cost of the class was $25 and included me as Donna’s guest. It also included a half gallon box of worm castings and four vegetable starts.

The transformation of an abandoned cotton field into a garden and desert oasis in just five years is amazing. The ten acres have about two acres taken up by various buildings and the rest is either dedicated to compost rows or gardens with fruits and vegetables.

Donna bought compost along with about 300 red wiggler (sometimes called red wriggler) worms. She finished filling her raised bed on Sunday and it has an in-ground compost tub which is a worm feeding station. We keep vegetable scraps in a container in the kitchen which we will transfer weekly or so into the compost tub and mix it with paper, cardboard and leaves. The worms will digest this stuff and transform it into plant nutrients. I find the whole concept amazing. I’ve watched several You Tube videos describing the process.

The worms can move freely in and out of the in-ground compost tub through holes in the sides. They will travel about in the raised bed, aerating the soil and depositing nutrients. They return to the compost tub to feed.

I cut a water dripper hose to the right length to fit the bed and we set it up on a timer. When the timer detects sunrise, it runs the dripper for 15 minutes to deeply and gently water the raised bed. In about six to eight weeks, we should have fresh tomatoes. Donna already has basil ready to harvest and she has sugar snap peas started along with a few other vegetables. She has marigolds in the corners of the bed to keep pests away. This should keep Donna busy.

Meanwhile, I’m continuing to work at learning astrophotography. Tuesday I made another attempt at Jupiter, but atmospheric conditions had layers of wind and temperature gradients that made it very difficult to get a sharp image. I tried a different approach. I used the William Optics Z73 refractor. It has a focal length of 430mm and much lower magnification than my Celestron 8SE which has a focal length of 2032mm. I used a 2X barlow on the Z73 to double the focal length and thus the magnifaction to try to capture Saturn and Jupiter. The results were still unsatisfactory. The only thing I can do is keep trying and hope for better conditions as the weather cools.

I turned my attention to the moon. I removed the 2X barlow and used the Z73 at its native focal length. By using the maximum sensor area of the ZWO ASI678 astrophotography camera, I could just fit the entire surface of the moon in the image. I photographed the moon on successive nights – I’m amazed at the changes in the moon view that occur in 24 hours.

The moon is waning – there is less surface area illuminated each day. I had a better exposure balance on the second night – I’m learning.

This is a detail view of the upper portion seen in the photo above

In the detail view above, the upper left has the craters Hercules and Atlas. Hercules is about 44 miles in diameter and Atlas is about 54 miles. Below them is the upper portion of Mare Serenitatis. Ancient astronomers named the dark, smooth surfaces of the moon mare (plural is marie), Latin for sea. They mistook the dark, smooth appearance as water. Actually they are large basaltic plains, the result of volcanic activity on the moon long ago. On the right side of the picture is the terminator – the name for the line where the illumination stops and the remainder of the surface is hidden in shadow. That is the Taurus mountain range right at the terminator.

I should mention the feature near the bottom right of the full moon picture. It’s the crater called Tycho with what appears to be rays radiating from it. These rays are formed by the ejecta created when an object collided with the moon forming the crater. We only see the rays on relatively young craters. As they age, the space environment with space dust and heavy doses of radiation darken the rays until we no longer see them. Meteors or asteroids collide violently with the moons surface – there isn’t an atmosphere there to create friction to slow them down or burn them up. The crater Tycho is relatively young – it was created around 100 million years ago!

Donna prepared a new recipe for chicken thighs called One-pan chicken thighs with coconut creamed corn. This recipe is a keeper for sure.

Sticking with the chicken thigh theme, she made another new recipe with boneless chicken thighs called skillet chicken with turmeric and orange. Served with steamed rice and sauteed spinach, it was delicious.

The weather has cooled in the last week – daily highs are upper 80s to low 90s. This is making outdoor pickleball a little later in the morning possible. Unfortunately, most of the pickleballers here in the park stiil want to start at the crack of sunrise. My astronomy sessions and early morning pickleball are at odds with each other – one has me up late, the other demands early rising. I enjoy outdoor pickleball more than the indoor game. I can see the ball better, it doesn’t skid on the floor and the level of play here at Viewpoint is generally higher than the recreation center.

We’re looking at a rainy weekend with thunderstorms possible. Donna turned off her automatic drip irrigation last night. It’s starting to rain as I type this.

Buying, Selling and Trading

It’s been nearly a month since I added a post, so here are a few lines and pictures. In my last post, I went over my woes with the Celestron NexStar telescope mount. I’m happy to report the Sky Watcher HEQ5 Pro I replaced it with has been great. It’s a little harder to set up, but it tracks targets nicely and is very sturdy. I found a buyer for my old mount and shipped it off.

I used the Sky Watcher with the Celestron 8SE SCT telescope to image Jupiter. Jupiter is a harder target than I thought it would be. In fact, astrophotography as a whole is a lot harder to learn than I thought it would be. I’m not getting the detail I would like. There are many steps involved to capture a succesful image.

First you need to achieve focus on a distant object – hundreds of thousands of miles away. Then you have to find the right combination of gain and exposure time for your camera – kind of like setting aperture and shutter speed on a conventional camera. The rotation of the earth and the orbit of the object come into play – the target doesn’t just sit in the center of the frame. What we do is basically shoot a video recording where we can adjust the frame rate of the video and set the number of frames we want to record. I control the camera with a small laptop running a program called SharpCap, developed by a British astronomer.

Once you have accomplished that, the raw image needs to processed. There are some really smart guys that have developed software specifically for this. They are astronomy enthusiasts and many offer their programs as free-ware for amateur, non-commercial use. I use three of these programs to process my images.

The first is called PIPP – planetary image pre-processor. This program takes the individual frames and aligns them so the image is centered in every frame. I typically shoot 2,500 frames or so at a time.

Next I use AutoStakkert – a program written by a Dutch astronomer – to sort each frame by quality of the image. Then I choose how many frames I want to keep by rejecting all below a certain quality threshold. Autostakkert then “stacks” or combines these frames into an image. This is called “lucky imaging,” because we are lucky to get a percentage of frames with a sharp image, largely unaffected by atmospheric conditions.

The output from Autostakkert is then opened in RegiStax 6 for sharpening, de-noise and color adjustment. I may use Photoshop for a final touch up. Here are few pictures – crude compared to professional and many amateur results, but I’m learning and will get better at it.

Jupiter

I bought a another telescope – I found it on the classified ad section of a site called CloudyNights. This is a completely different approach than my Celestron 8SE Schmidt-Cassegrain reflector. This one is a refractor type telescope – one of the oldest telescope designs. It’s simple and well-made with high-quality optics.

It’s from a company called William Optics and it’s model is ZenithStar 73. It has a 73mm objective lens, 430mm focal length and it’s relatively fast at f5.9. I mentioned quality optics – the objective lens in this telescope is ground from a material called FPL 53 optical glass. FPL 53 is made from a synthetic fluorite crystal grown in a lab by a Japanese company called Ohara. FPL 53 is a desirable material for telescope lenses.

When used visually with an eyepiece I can see the entire surface of the moon with this ‘scope and it is less affected by atmospheric conditions than the larger Celestron. More magnification requires a stable atmosphere for sharp images. The astrophotography camera I use increases the magnification of the image with this ‘scope though. Here’s a moon shot I took Saturday night.

I described this astrophotography session as a near disaster on Facebook. I think considering the real disaster that was hurricane Ian, my description is a bit of an over-reach. Here’s what happened.

I set up my mount and telescope behind our back deck, adjacent to the golf course behind our place. I use a small card table for a couple of small cases with some of the gear I use and also place a small notebook computer on it to record the image. My plan was to take a shot of the moon, then move to Saturn and finish the night with Jupiter. I wanted to try the Z73 ‘scope on the planets just to see what I could get with it.

After I captured the image above, I programmed the mount for Saturn. While the ‘scope was slewing toward Saturn, I heard water sprinklers start up. Oh no! The golf course decided to start watering at 8:30pm – I’d never seen them water much past 7pm before. I closed the notebook computer and ran it over to our deck, then went back for the rest of the gear. Donna was out and she started grabbing things as well. We weren’t quick enough – the sprinklers got us and my gear briefly before we could get everything out of range.

I’ll have to rethink my telescope set-up position for future sessions. This is not so easy – I thought I found the perfect spot to get clear views of most of the sky. Well, that’s probably more about astronomy than you ever wanted to know.

Donna went to Vermont for eight days, beginning on September 13th, to visit her parents. While she was away I decided to make another change. We’ve been using our 2015 Nissan Frontier for daily transportation. When I bought this truck, it was intended to be towed behind our motorhome as we traveled about. For this reason, I bought a used work truck with a manual transmission and no frills.

We won’t be towing behind a motorhome now, so why drive a beater and shift gears manually? I looked around for something more comfortable that we could live with. The best solution would be a company lease car – as a Volkswagen retiree, I have lease car privileges that allow me to select a new VW on a very favorable 12-month lease. However, in the current state of things, new cars are in very short supply and lease car choices are extremely limited.

I found a nearly showroom condition 2019 Jeep Compass with all of the bells and whistles and only 36,000 miles on the clock. So, we went from a manual transmission, noisy truck with manual roll-up windows to a loaded compact SUV with power everything. Of course, this means electronic control modules galore and lots of potential for things to malfunction, but you only live once. I traded our truck and put a dent in my savings as I don’t like to finance anything – we are debt-free other than the lease on our park model home lot at Viewpoint Golf Resort.

Donna returned from Vermont on the 20th, so I’m back to eating like a king. Here’s a dinner plate she made. The main dish is parmesan crusted tilapia with cauliflower penne pasta and steamed spinach on the side.

We’re past the monsoon season and humidity levels are back to a more normal range of 10-25%. The triple-digit heat is behind us as well with the forecast calling for low 90s and mid-to-high 80s for the rest of the month.
