Articles I Like: Five Changes Facing Public Employees When They Return to the Office – If They Do

PolyWogg.ca
May 22 2020

As a public servant, and similar to every other industry, there is a lot of speculation about what post-Covid workplaces will look like. Many of our operations can be done well-enough from home, and the challenges we have now are mostly about IT infrastructure, home office solutions, and privacy. Much of our work is digital and email-enabled, so it’s not a giant leap to work from home. We just traditionally haven’t done that transition for all the usual pressures related to remote workers and supervision/monitoring, and some unique pressures related to privacy, taxpayer dollars, and supporting Ministers in person.

Paul Taylor over at Governing.com wrote an article about five changes he sees coming to the public service post-Covid. Here’s an excerpt:

Your Cubicle. Our Conference Room. Where Did They Go? Your space may get bigger as facilities staff reconfigure space to conform with the 6-foot separation requirements. Coupled with limits on group size, that is likely to grow cubicle row into what were once conference rooms.

…

Beyond the Point of No Return. Social distancing is bound to spread employees across more square footage than agencies have to reconfigure to handle everybody at work. What’s more, as governments confront the need for budget cuts in the tens and hundreds of millions, the public-sector layoffs announced to date are likely to rise exponentially as the tax base shrinks.

Reading Michael Swanson’s “The NexStar User’s Guide II” – Chapter 07 – Connecting a PC, Mac, Tablet or Smartphone to Your Tablet

PolyWogg.ca
September 8 2019

For reviewing purposes, I skipped over the short Chapter 6, focused on Sky Portal operations, as I’ll do that chapter after I have a chance to connect to my tablet and test some of the operations. I thought of doing the same for Chapter 07, Connecting a PC, Mac, Tablet or Smartphone to Your Tablet, but it’s a short chapter, and easily dispensed with here.

Some of the highlights:

P.165 – Wired Connections for RS-232 Hand Controls…I knew that most of the wired connections used a USB to Serial adapter, and plugs in to the RJ-22 Jack (I thought it was an RJ-45, but apparently not!). However, one “new” thing in the guide is that there is a way to do a wired connection to a tablet or smartphone using SkyWire + Sky Safari with an iOS device. I had no idea there was an option for a physical wire connection. I might have skipped the dongle wifi if I had known that earlier, as there can be challenges maintaining connections.

P.165 – Wireless connections…As with the wired one, I didn’t know people had attempted doing it with BlueTooth but it sounds way more exciting than the wifi connection.… Read the rest

Reading Michael Swanson’s “The NexStar User’s Guide II” – Chapter 05 – NexStar and StarSense Hand Control Operations

PolyWogg.ca
September 7 2019

Chapter 5 (of Michael Swanson’s “The NexStar User’s Guide II”) is entitled NexStar and StarSense Hand Control Operations and you would be right if you assumed this was going to more like a software manual than a telescope manual. It is a highly specific reference manual for the use of the hand controller and reading it page by page is for the hard-core geek only. But it is full of fantastic info that I didn’t know enough about, even though I’ve worked with the hand controller for years. These are the highlights for me:

Pg. 128 – Adjusting slew rates…I knew how to manually adjust the slew rate (MOTOR SPEED then press 1-9 where 9 was the fastest). I really only use 3, 6, and 9 for rates though. 9 if I’m going a great distance, 6 if I’m adjusting for centreing, and 3 if I need very fine adjustments while doing astrophotography and looking at centreing something on the screen. However, I didn’t know that if you were slewing in one direction (say left) and also held down the opposite button (i.e., right), it would temporarily speed up to rate 9. I have no idea when I would ever use that, but it’s good to have.… Read the rest

Reading Michael Swanson’s “The NexStar User’s Guide II” – Chapter 04 – Alignment

PolyWogg.ca
September 3 2019

Chapter 4 of Michael Swanson’s “The NexStar User’s Guide II” is entitled Alignment and is the chapter that made me want to buy the book and read it cover to cover. Readers of the blog know that I struggled with alignment for my NexStar 8SE (Solving alignment problems with the Celestron NexStar 8SE) and Michael’s online resources were helpful in resolving some of them, or at least narrowing the problem. I even held off buying the book because he said Guide II was coming and I should wait over Guide I. Then I managed to solve most of the alignment issues, and so when his book arrived, I didn’t devour the whole book right away. I just cruised through the Alignment chapter. Then this past summer, I went back and re-read everything in order.

Here are some highlights from Chapter 4:

Backlash compensation (P.87): A great element for those of us with slightly older scopes whose mounts are no longer “factory fresh”. My son’s new 4SE? Dead tight regardless of the direction I’m slewing. My 8SE? There’s a bit of a lag. I tried adjusting this 3 years ago and just got confused. The new guide has it very clearly laid out, and I’ll be attempting a fix later this month.… Read the rest

Reading Michael Swanson’s “The NexStar User’s Guide II” – Chapter 03 – Overview of Celestron’s Alt-Az Computerized Telescopes

PolyWogg.ca
August 30 2019

I like to blog about non-fiction books as I read them, as it helps me both synthesize and retain the info. Chapter 3 is a general overview on all the computerized scopes in Celestron’s arsenal, and I found myself liberally highlighting as I read it. Here are some highlights:

  • P.57 — a great overview of the different processors in the mount, including some of what the processors in the mount do (drive the motors) and the hand control (determining the correct tracking rate)…I was initially confused about something in the manual, as it said the hand controller sends the update to the mount every thirty seconds. I wasn’t sure if this meant it sends a “movement” command every 30s (as that seemed too slow) or a rate adjustment every 30s (adjusting the existing tracking speed), and the author confirmed the latter. Now rereading it, it was already clear, I think I just confused myself;
  • P. 69 — I was surprised to see that there are CPC mounts that are actually quite well-designed for accurate tracking and thus support astrophotography. Maybe something to aspire too, instead of going Equatorial some day;
  • P.78 — Good overview of the various types of hand-controllers, …I think I have the NexStar+ serial (Celestron button + RJ45-like jacks).

Reading Michael Swanson’s “The NexStar User’s Guide II” – Chapter 02 – Astronomy Basics

PolyWogg.ca
June 26 2019

I mentioned previously that it helps me to blog about NF books as I read them — kind of like transcribing my notes into something more coherent that my brain can recognize. Chapter 2 on Astronomy Basics in the NexStar User’s Guide II is a similar outcome. Here are some thoughts:

  • P.12 — Constellations…There are 88 constellations that divide the sky…I always assumed there were WAY more than that. I’m curious if each of them will fit in an EP at 50x magnification which is my smallest / lowest power option;
  • P.13 — Meridian…I knew horizon and zenith of course; I had not heard the term “meridian” to indicate a line going from northern celestial pole to southern celestial pole through the zenith to divide items west and east;
  • P.15 — Magnitude…I wasn’t aware that a 1 magnitude increase in power equaled a 2.5x increase in brightness…I guess I just assumed a flatter linear scale. My son’s 4″ has a magnitude limit of 12.5, while my 8″ has 14, an increase not of simply 1.5 but of closer to 1.25 x 2.5 = 3.125 i.e. I can see way fainter stars. However, I have never figured out what a reasonable limiting magnitude in my backyard is, or anywhere else.

Reading Michael Swanson’s “The NexStar User’s Guide II” – Chapter 01 – Introduction

PolyWogg.ca
May 4 2019

I have a Celestron NexStar 8SE telescope, and I have had some, umm, challenges dealing with alignment issues (Solving alignment problems with the Celestron NexStar 8SE). When I started surfing the ‘net to find some solutions, it didn’t take long to find out about Michael Swanson, the resident online expert for all things NexStar. He wrote the previous guide, he has an active website, he participates in online discussion forums. He’s everywhere you need him to be, except maybe in your own backyard when you’re viewing.

I finally caved and said, “Yes! I need that book!”. And then found out the new edition was about to come out. So I waited a bit, pre-ordered it, waited a bit more, finally got it, and immediately put it on my TBR pile and didn’t do anything with it. Sigh. I have about eight other astronomy books I want to devour cover to cover too, but this one is more practical. One of the few things that works for me with NF books when I’m dragging my feet to read them is blogging as I go, so I am going to try that here. I did it with Jeffrey Kottler’s “Change” – Chapter 1 and the 13 chapters that followed it before doing my final book review ( Change: What Really Leads to Lasting Personal Transformation by Jeffrey A.… Read the rest
