6. The NexStar 6 SE
The NexStar 6 SE
The packaging was very good-each sub-assembly was packed in a separate corrugated container inside the double walled outer container. The optical tube assembly came packed in dense foam, while the controller arm and controller were attached to the tube. Assembly is easy: you just pop the scope on the tripod base.
The first wrinkle was that I needed a Philips screwdriver. The finder mount was attached to the finder, not the telescope, in contradiction to the instructions. I removed the mount from the finder and secured it to one end of the telescope. Aligning the unit-power (no magnification) finder was somewhat of a chore. Even with the low power Plössl (25 mm) eyepiece included, the red dot has to be right on target for the target to show up in the telescope.

The Thompsons recommend a unit-power finder as a necessary accessory; since it is included, most of us will want to purchase a standard finder! This unit-power finder projects a variable brightness red LED dot on the viewing field. The red dot projection is quite good. The hand controller 2 line LCD display is very bright-a deep orange-red-but can be turned off. The hand controller, with its bulky cord, does not snap firmly in its mount, so I sometimes let it dangle.

Accessories include:
- A 25 mm Plössl eyepiece
- The unit-power finder
- A star diagonal
- An RS-232 cable
- A tiny bubble level
- Remote control software (for your laptop)
- “The Sky” Level 1 Planetarium software
- NexRemote (software that controls the telescope via your PC)
- A warranty card (two-year warranty)
- An extra eyepiece cover
Note the yellow solar viewing warning tag. To get the scope to slew towards Sol, you’ll have to enter a restricted menu choice at the beginning sequence when addressing the controller.

The hand controller software is generally good, and there is a site dedicated to the fine points of NexStar computerized control, observer lists, and so on
The NexStar 6SE has a focal length of 1500 mm, and you compute the magnification by dividing by the eyepiece focal length. For the included eyepiece, that’s 60X. The hand controller is firmware upgradeable by flashing the ROM. To do this, you need a DB-9 serial port (or USB to DB-9 adapter).

A minor annoyance is that my scope sample’s lens cover keeps falling off, because there is not enough of a friction fit. It would be a good idea to have a place on the tripod tray to hang the cover. I also would have preferred lever locks on the tripod legs, rather than the set screws used.
As others have reported, the Celestron controller eats batteries, and it requires 8 AAs. I was unable to power up with a mix of a few days older than freshly recharged NiMH batteries. When I replaced these with fresh alkaline batteries, I used the telescope for almost two hours before the slewing rate slowed considerably. You will want to add the Celestron power tank, a portable 12 V battery, or the cigarette lighter power adapter to your purchase. I also recommend purchasing an additional very good quality eyepiece or two, a better diagonal, and filters.

GoTo mounts are for lazy people who don't really understand the essence of observing the sky. It's certainly a fun thing to create if you are an engineer, but if you're considering using one, take my advice and buy a book with pictures of the Messier catalog, it's a lot cheaper. A true amateur astronomer never uses those revolting, despicable, hideous GoTo mounts. Get a real standard equatorial mount. Get a good sky atlas. Get a pair of quality binoculars. Know your sky! That's astronomy...
A sensitive topic to be sure. But the point of the article was to encourage those who have an interest in astronomy but never bit the bullet. That is, they don't own a scope because they aren't willing to learn all that needs to be done to find stuff. OK, even lazy. And our readers totally grok computers.
Many amateurs started by using a GoTo. IMHO, the more astronomers the better. Talking to denizens of LAAS and reading cloudyskies.com, there is little sense of elitism. All amateurs are welcome, even and esp. those with GoTos.
I didn't have room to talk about the wedges that covert yoke mounts to equatorial mounts, but they exist for many yoke types. That way you can have the best of both worlds.
Finally, one of the books I recommended does just what you suggest: tries to teach the night sky so you can find stuff without using (or even using) a GoTo. Hope this addresses your comments.

I think the guys who say to get a star chart and spend 6 months learning how to find and track things are missing the point and living in the 19th century.
The fact is that these new generations of scopes make astronomy so much more accessible to people who find astronomy interesting but don't have the time or ability to invest. They also make it simple to introduce new people to astronomy by quickly showing them lots of interesting things.
Plus, as a computer geek, there is nothing more fun than plugging your telescope into your laptop, hooking up a camera and driving it around from your computer. Do an easy DIY project like adapting a webcam to use with the scope and you have yourself tons of fun *and* you learn the night sky, you just don't waste months of time trying to figure out how to see anything.
I totally agree with smurfdog - you spend more time observing and imaging objects than trying to find them - and most of them are very dim anyways. THe manual method of finding objects is definitely 19th century stuff.
Science is ever changing and self-correcting. To memorize the sky from Earth is one thing and to explore the universe is another. Technology makes Astronomy possible for all who are willing to learn and grow. Why not use both to your advantage.
Doug,
I really praise the point of your article. I also love to teach everything I know about the topic to anyone who's interested in the subject, like most amateurs.
Like you said, there's no to little sense of elitism in those groups. But I also know this: Like all the really rewarding things in life, Astronomy requires persistence and solid interest.
I decided to comment your article since I disagree on some things you wrote and that contrast may help people who read it, look at the picture from another angle.
Trying to find Deep Sky Objects or the planets (very easy with little experience and knowledge) in the sky, is where most of the fun is! Having a computer doing it for you is like you own a Porsche and let a chauffeur drive you. The only difference here is that, unlike the chauffeur, the computer has no fun at all!
I didn't find anything interesting on cloudyskies.com, apparently is just a domain for sale. Did you mean www.cloudynights.com?
If your interest is solid, you've got nothing to fear, understanding the sky is a lot easier than most people think.
Diogo.
Diogo et al,
My bad! Yes of course I meant www.cloudynights.com. It's a great site for advice, and mostly cogent tips on purchasing and use.
I think we can agree that for some, starting with GoTos is a great way of getting into astronomy. Then you can progress to star charts and maps, relying less on the GoTo. I want to encourage people to begin this exciting hobby.
Amateur astronomers are one of the few science disciplines where amatuers can and do make professional level contributions!
And even though I understand how the SkyScout works, it is unbelievable to actually use it and watch it ID an object, or have it guide you to some random star in its database...Awesome product. For me, this really helped me better learn the night sky. It's like using a crutch (or a chaffeur) then weaning yourself away from it and driving yourself. Much less pain, and kick butt fun.
Hope this answers your concerns.
Clear skies!
Doug
Doug,
I am a beginner in the field of astronomy and astrophotography and I would like to purchase some equiptment. Im not exactly sure what types of telescopes and astrophotography equiptment would be best for a beginner and it would be great if you could offer me some advice. I have done a lot of research on telescopes preferably under $500 and CCD cameras along with laptops. If you have any advice that would be great! Thanks.
