A year or so ago we bought a Subaru Outback, and then an Aluma trailer on which to haul it behind our class C RV. The Outback fits perfectly on the Aluma trailer, but figuring out the best way to tie the Outback down on the trailer was a bit of a puzzle.

A friend of ours (with the same trailer and Outback) suggested these lasso tie-down straps, which we tried. However, our trailer didn’t have attachment points in the best places for using those straps, and we improvised. Long story short, the straps didn’t work very well for us and frayed and broke–not very good when you’re towing down the highway. A better solution was needed.

Finally. I’d been waiting for weeks for an evening that would provide decent enough conditions for me to attempt my first imaging session with my new telescope, camera, and mount. Between clouds and smoke from forest fires, I’d been stymied for quite some time, but last Thursday evening finally presented clear skies and a little dark time before the moon rose so I could set everything up and try some long-exposure imaging of deep sky objects.

My first attempt at imaging M31, the Andromeda Galaxy.

The William Optics UniGuide 50mm guide scope

In my quest to put together a decent starter package for doing deep sky imaging, I purchased a William Optics UniGuide 50mm guide scope and a ZWO ASI290mm mini guide camera to use for guiding my main telescope during imaging. Both appear to be fine pieces of equipment, but when I did some bench testing I discovered that in order to bring images to focus in the ASI290mm mini guide camera, it had to be positioned in the guide scope such that it was just barely inserted. Some additional length in the guide scope would be a good thing.

Well, comet Neowise has come and (pretty-much) gone, but it put on an impressive display while it lasted. I managed to get out my camera one evening and take a few pictures, including this one:

Comet Neowise, taken July 20, 2020 from Woodland Park, CO (elevation 8400 ft). Taken using a Canon 250D DSLR with a Canon EF 50mm lens at f/1.8, 5s exposure at ISO 3200, modestly processed with Affinity Photo.

I’ve been running my NexStar 6SE scope in the field using an old 12V 7-Ah gel cell battery for awhile now, but it’s kinda heavy and has to sit on the ground, meaning I have to pay attention to not getting the power cord wrapped around the mount as I slew the telescope. I really wanted to find something that was light enough to attach to the arm of the mount itself but still had enough power in it to run the scope for at least an evening. Surfing some of the message boards, I found several reports of people using battery packs from TalentCell. The message board posts claimed up to several nights of observing with their battery packs. It sounded like I had found the answer.

Wifi Connections Between Scope and Laptop

So, this installment of the series didn’t work out quite like I expected. While, in theory, everything I describe below ought to work, I found problems maintaining the wifi connectivity between the NexStar mount and my laptop. Thus, all I can say is give it a whirl if you want, but I make no guarantees. I’m leaving the instructions up here in case you feel the need to give it a try. If you really want to use your laptop to control your NexStar scope, wired is probably best (although I’ve had some success with bluetooth, too, which I’ll cover in another installment).

In Part 2 of this series we went over the basic setup for connecting your NexStar to a laptop using a wired connection. It works great, but cables between your telescope and laptop can be a real nuisance, because you have to start worrying about the cables wrapping around the telescope as it slews in azimuth (although turning “Cord Wrap” on in the hand controller can mitigate that). In general, cables in the dark seem to me like a recipe for disaster. So in this installment, we’re going to cover connections between telescope and laptop using Wifi. (The next installment of this series will cover using a smartphone or tablet instead of a laptop to connect with the NexStar via wifi.)

Wired Connections Between Scope and Laptop

In Part 1 of this series, I discussed some of the reasons why you might want to use your laptop or tablet to control your NexStar, and went over some of the options for how you can accomplish that. In this part of the series we’ll get a laptop set up to control your NexStar using the Stellarium software package through a wired connection between the scope and the laptop. With Stellarium, you’ll be able to point and click to easily slew your scope to any object you’d like. Stellarium also is capable of showing a ton of information about that object. It also provides a very pleasing and easy-to-use interface. We’ll go through the process from start to finish. Even if you decide to use a different connection type (WiFi or Bluetooth), the instructions for Stellarium will remain pretty-much the same.

The fundamental requirement for controlling your NexStar with a computer of some sort is, of course, establishing communications between the two. As far as I know, a wired connection can only be done between a computer with a serial port or a USB port and the scope–tablets are not supported for wired connections (but let me know in the comments below if you know of a way).

Having recently gotten myself a new Windows 10 laptop (an Acer Aspire E 15 that I really like), I’ve been going through the process of getting everything set up and installed the way I like (I’m kinda anal retentive about that). That gives me cause to explore new possibilities, like “how can I get my Google contacts and calendar (from my Android phone) to sync up with my installation of MS Outlook on my laptop (which I use for email)?” I’ve asked that question before but never found a decent answer. This time, though, I found a great solution, and it’s free!

GO Contact Sync Mod is a utility I found that runs in the background on my laptop, reaching out to Google’s APIs to keep my Google contacts and calendar sync’d with those in MS Outlook. It has a straightforward user interface where you can define the rules for reconciliation (like “if there is a conflict, the Google contact should overwrite the Outlook contact”). You can tell it how often to perform the sync and it will do so quietly in the background. I’ve been using it for a few weeks now and it works so well that I forget it’s there.

(Why don’t I just use GMail and omit MS Outlook entirely? I have my own domain, including email addresses, so I don’t use a GMail address. And I much prefer MS Outlook’s interface to GMail.)
