Happy New Year, first of all. I hope you all had an enjoyable holiday season and a merry Christmas. We certainly enjoyed Thanksgiving and Christmas. Donna’s Good Neighbor group shared holiday meals with many older residents of Viewpoint that were homebound or alone over the holidays.
We’re staying busy as usual and settling into our winter routines. Of course, Donna is involved with many more activities than I am – she’s always on the go. I’m running pickleball coaching sessions once a week and taking tennis lessons two days a week. Something that has become a habit is Friday afternoon/evening visits to RJs cigar lounge with Mike Hall. We catch up on events and solve world issues. Sometimes Mike’s wife, Jodi, and Donna join us. I usually puff a premium cigar with rum on the rocks.
Donna has been after me for a while to do something about hearing impairment. I have hearing loss – it’s no wonder really. A lifetime around shop machinery, playing electric guitars, racing motorcycles and shooting guns takes a toll. For some reason, I’ve resisted checking out hearing aids. Since hearing aids were approved for over-the-counter, prices have dropped dramatically.
I did some online research and found that traditional hearing centers convince patients that their services are required and they offer expert advice at no cost. In reality, they bake the cost of their enterprise – building rent, employment expense, etc. – into the price of the hearing aids. Nowadays, hearing tests can be done online with decent headphones. Test results can be analyzed and hearing aids with custom correction profiles can be ordered and shipped to your home.
I chose a company called Jabra – they’re part of the GN Hearing group. They’re headquartered in Denmark. I took the test on their site and submitted my results. I ordered a pair of their Enhance Select 100 hearing aids for $1699. I also downloaded an app for my Samsung Galaxy that connects via Bluetooth to my hearing aids – I can adjust them for different surroundings and scenarios on the fly with my phone.
I can hear so much more now. I love them and wish I would have done this earlier. If you are interested in their products, I have a link to a discount for referrals. I have an online Zoom appointment with a Jabra specialist on the 11th to go over any questions that may have come to mind after using them for a while. They can also customize the settings if I wish to modify it. The purchase price included three years of warranty and support.
When I go to the Cigar Lounge, I change the hearing aid setting to “Restaurant.” This makes nearby conversation easy to hear while muffling background noise and conversation. On the tennis or pickleball courts I switch it to “Outdoors.” This blocks wind noise and muffles loud sounds. Pretty convenient.
I’ve been putting time into astrophotography – nothing new there. It takes about five hours for a two-and-a-half-hour imaging session when you consider set-up, calibration and tear-down. In October, I imaged M31 – the Andromeda Galaxy. This galaxy has been a nemesis. I’ve had a hard time getting enough usable data to process a good picture. It seems like Murphy’s Law strikes every time I go for this target. One night I had good conditions and set everything up only to have communication failures between my gear and laptop. After two hours, I gave up. I ordered some replacement cables. Then I had to wait for another clear night with good seeing conditions. It finally came about and I captured about two and a half hours of 60-second exposures on December 14th.
A week went by before I had good astrophotography conditions again and I set up at the east tennis court parking lot here at Viewpoint. I captured another three hours. After culling out bad frames, I stacked and integrated 297 frames for four hours and 57 minutes of data. I’m fairly happy with the result and I can give Andromeda a break for a while. Maybe next year I’ll see if I can improve it as my skills increase with more experience.
The Andromeda Galaxy is about 2.5 million light years away from Earth. I used my new William Optics GT71 telescope with a 0.8 reducer/flattener and Player One Poseidon cooled astrophotography camera. I used an Optolong L-Pro filter to fight the light pollution and moonglow.
Next, I wanted to capture something new. After looking at the best possibilities, I settled on NGC 281 – the Pacman Nebula. I chose it because it would be high in the sky from 7pm to 10pm. Telescopes work best on objects that are near the zenith – that is, overhead. That’s because when the objects are nearly straight up, there’s less atmosphere to penetrate. If we shoot at a low angle, we have to deal with much more atmospheric disturbance.
Once again, I set up and ran through calibration only to find communication errors. Data wouldn’t transfer from my camera to my laptop. After much wrangling, I isolated the problem to the USB hub. Most modern laptops only have one or two USB-A type ports. I need a minimum of four, so I use a hub for more ports. I was kicking myself when I realized the hub was the problem. I had all this software and equipment and I link it through a $20 hub from Amazon. Not smart.
The demands of an imaging camera and a guidescope camera along with mount guiding commands and so on put a lot strain on the hub’s ability to quickly distribute and transfer data. I did some research and found that most guys are using independently powered USB hubs – they don’t pull any voltage through the laptop USB port. That way constant voltage is supplied through a separate connection and the laptop port only handles data. I found a number of complaints about cheap hubs not working when it gets colder outside. This makes sense if you consider they are designed to work in your home or office where the temperature is fairly constant and only ranges from maybe 60 to 80 degrees Fahrenheit.
I decided to bite the bullet and get a good hub. I ordered a Pegasus USB hub that is considered industrial grade. It has a certified working temperature range of -40 to +185 degrees Fahrenheit. It took a bite out of my wallet at $200 versus the Amazon $20 hub, but I’m confident this one will work. Actually, I hedged my bet – I also ordered an Amazon $40 powered USB hub for back-up purposes. There’s no worse feeling than to set all of the gear up for a night of imaging, only to fail to even get started because of equipment failure – especially something as simple as a USB connection.
Once I had the new hub – which my friend Mike Hall calls the “Gucci” hub – I had wait out the weather. I finally had a promising night on December 30th. I set up at the east tennis courts and everything calibrated fine. There was a full moon, but as it was rising in the east, I was shooting almost straight up slightly facing the northwest.
This turned out to be the first time I experienced what appeared to be clear skies, but with so much atmospheric turbulence that I struggled to get usable images. After an hour and half or so, things seems to settle down and the session improved. I knew I didn’t have enough to create a decent final image though.
The next clear night was January 2nd. This turned out to be excellent seeing conditions and I captured more than two and half hours of 75-second exposures. The moon didn’t rise until about 9pm so I had good skies most of the night, light pollution notwithstanding.
I had to throw out about half of my first night’s effort, but kept nearly all of the second night – I think I only culled three or four frames out of 125. I had three hours and 52 minutes total integration time. The Pacman Nebula is in the constellation Cassiopeia, about 9,500 light years away from earth. If you remember the video game Pacman from the early 80s, the nebula resembles the Pacman about to gobble up some stars.
I captured this image with my AT115 EDT telescope and ZWO ASI533MC Pro cooled astrophotography camera. The light pollution and moonglow made it difficult to capture much of the oxygen gases that emit blue light, but I’m happy with the final result.
Donna got an air fryer and has been experimenting with it. It’s a story in itself, how she acquired the air fryer through a generous gift but then traded with a friend for a smaller air fryer. The original air fryer was too large for our small kitchen and storage space. Her friend Deborah had a new smaller one and was interested in a larger one, so they swapped.
One of the meals she made was air-fried tilapia. A simple meal ideal for the fryer.
Best wishes for 2024 – another trip around the sun.
