Best laptop for use with a go to scope?
Posted 02 July 2013 - 09:12 PM
Recently, my seven year old laptop- a Gateway 7320GZ- passed away. It had way too many issues of late, but it was always a pleasure to use with my scope.
So now I'm looking to buy a new laptop and I'm looking for best/worst experiences with various laptop vendors (Asus, HP, Samsung, Lenovo, Dell, etc). I'm not interested in using Apple products- I love Apple products, but I don't feel like setting up my iPad to use outside, and it doesn't run Cartes. I also am not considering Toshiba laptops at this time as the mouse pad on many of their laptops has an unusual surface that makes my skin crawl when I touch them.
I guess a cold hardy and dew hardy laptop is what I most want... but I'm not sure if they exist on the common PC market. Many laptops have lit keyboards that at first look tempting... unfortunately they are all white-blue lighting which is disastrous in astronomy! Anyone ever hear of or see a laptop with a red backlit keyboard?
Thanks for your input in advance!

I used a Toughbook CF-31 for about a year. I used it for troubleshooting, diagnostics and reprogramming in the field. Nice computer and very bulletproof, but hardly worth the price when bought new. They are made for use in far worse situations and environments than I put it through. It's designed for use by gorillas. A regular quality laptop will last as long if cared for and is cheaper to replace.

In my experience you don't need something like the Toughbook unless you are hiking with the laptop or something.

If you're set on a laptop instead of using a tablet, I'd recommend looking at ultrabooks (you know, the me-too wannabe Macbook Airs). They'll have the long battery life you'll want.

I have an iPad3 (great screen) but I also have an iPad1 which is the best of all as this will run all night on a charge - upwards of 11 hours with the screen dimmed.
In recent months a lot of guys are adding a SkyFi box to their mounts here and using the iPad with Sky Safari.
On dobs I've seen, the common theme here seems to be a big stalk on the base with a bracket to hold the iPad securely where you can see it without bending, and it will rotate following the scope as you turn in azimuth.
You could rig up a holder on one of the fork arms on a CPC.

For field use, battery life is nice. You don't need much processing power if all you're doing is using the PC to slew the scope to targets. I'd recommend something as cheap as possible using one of Intel's new dual core mobile "Haswell" chips. An Ultrabook using a lowe power Haswell (like a MacBook Air wannabe, but stuck with Windows 8) would probably be best.
iPad is the way to go. Really. Laptops in the field suck eggs by comparison. Get a Lifeproof or similar Griffin case for you iPad. Waterproof, dew proof and shock proof. Slap a big swath of Velcro on the back of the case. Slap a big swath of opposite Velcro on the leg of the tripod. Now you have a place to stick it between uses. Try that trick with a laptop.
Skip Cartes du Ciel. Sky Safari for iOS PWNS it. And isn't all that expensive. You have a couple of options for pairing your iPad to you mount for purposes of driving with Sky Safari. Sky Wire wired connection and Ski Fi wireless hub. You can get by with a low-spec iPad 2 or better, too. 16GB is plenty. The iPad Mini is a great option too, as it has a smaller more mount-friendly footprint.
A third option that I'm playing with currently is a uber-cheap Android tablet (I'm using a Samsung Galaxy Tab 2), Sky Safari and a bluetooth adapter. Clunkier than the iOS implementation, but it works on the cheap. ~$200 gets you the tablet, the app and the adapter.

If you are leaning towards a laptop, I say go for the Mac. You can get skysafari for the mac osx. I have a MacBook Pro. Though I only use skysafari on my iOS devices, I can see getting it eventually. I also installed windows on my Mac via boot camp so I can use other astronomy programs nor compatible with Mac, mostly for imaging.

Skysafari with the iPad and skyfi wireless link is the way to go. It is soo easy to use and it beats lugging a laptop around. You can also use it with the iPhone.
How do you autoguide without a laptop? Standalone?

That said, it is just a matter of time before some geniuses come up with Android and iOS guiding and astro-image processing solutions. The chips keep getting more powerful and lower in power demands. Mobile devices soon will have more computing horsepower than PC laptops from a decade ago. I still use my decade-old laptop in the astro-shed to run SkyTools 3. I suspect that the next generation iPod chip using the upcoming A8 silicon will come close to what that clunky old beast delivers. In fact, I think Southen Stars would be very smart to start developing imaging solutions as add-ons for Sky Safari.

Panasonic Toughbook is what you need:
Except for the fact that they are not all that tough. I work as the Information Systems Manager for a transit agency. We have assigned both toughbooks and the Dell equivalent to our Diesel mechanics. They still break them! And they are harder to repair once broken because of the added padding.
+1 on the sky safari. You can get a refurb IPAD for about $400.00. Also, android devices like the Samsung Galaxy Note (Costco has them new for $399 if I remember).
The PC route is not all that bad. Look on the Dell Outlet web page (www.delloutlet.com). I really like the Dell XPS 13 if you can find one. They are extremely light, have an SSD drive, and run Windows.

iOS is much more polished, and Sky Fi/Sky Wire much easier (and "consumer") to setup and use, but you can do wireless Sky Safari on the cheap using Android. My biggest challenge, after assembling all of the extra bits needed to make Android work in this role was with the Samsung device specifically. Night mode is almost too dim in Sky Safari on that device, unless you are at a very dark site and use reading glasses if you are an old dude like me. I meant t play around with the Tab 2 last night to see if adjusting the native device brightness higher (rather than setting it to auto) and then switching to night mode in Sky Safari would correct the issue, but didn't get around to it.

* iPad Mini w/ Sky Fi - The simple solution.
* Nexus 7 w/ Sky Fi - The geek solution. Requires rooting for AdHoc wi-fi support but has some nice extras like multiple options for red screen filtering throughout the OS. I'd personally never buy a "skinned" Android device like a Samsung, stock only for me.
* Lenovo IdeaPad Y Series - The "If you ever think of getting into imaging" option. Good mix of build quality, performance, along with a night friendly lighting scheme.
