Cool Argo Navis vs Go-To

Hi guys,

I need something to help me find stuff in space! In Rocky, I was well versed with one part of the sky (Pointers, Crux, Scorpians Tail, Jupiter, Sirrius, Saturn, Orion's belt, Canopus, etc..), but now I'm in Brisbane, the sky's slightly different and there's a bit of light pollution...I have no idea what I'm lookin at. All I know are Jupiter, Scorpian's tail, pointers and Crux.

I was able to find stars in Rocky because I had those bright stars to try and judge where I needed to look. Now, the brightest one I have is Jupiter.

Anyway, if you have suggestions on how I should look for stuff, please let me know...otherwise, I was thinking about these argo navis and go-to systems. Which should I go for? I think I have an orion eq-3 mount, and the scope is listed below. I'm also attempting very, very amateur astrophotography.

Any suggestions?

Thanks!

EDIT: From what I have researched, the costs are:

Argo Navis system + kit + etc.. = $1000+

Go-To mount = $1400 - $1800 (EQ3, EQ5, HEQ5)

LOL..ok, is this a silly question? Is that why no one's answering? Are you laughing at me behind my back?

Hello DJ,

I just thought I'd reply so you didn't think you were being ignored. I'm pretty amateur myself...

As far as I have learnt, the argo tells you where things are, but doesn't drive your scope, you have to move it yourself. On the other hand, the goto will give you some tracking for long exposure photography (to get better colours and detail).

However if you are tracking on an alt-az mount, there is some rotation that may spoil longer exposures.

I'm sure someone with a little (lot ) more experience will reply to you post more comprehensively soon.

YOu can use argo navis two ways.

One is to use it as a push to system. Meaning you align and you push it to the object you are looking for.

Second it can be mated with servocat and become a great goto system. It will point perfectly all night. I love using mine and I find it so intuitive. Combined with servocat it is the perfect.

Hi,

Not a silly question but which way you go depends on personal preference.

The telescope you have is a 5"/F6 Maksutov Newtonian, made by Intes Micro in Russia. It is a very high quality telescope, unfortunately mounted on a very low quality and inadequate mount, made in China. Personally, I wouldn't waste any money adding any accessories of any description to that mount.

If it was me I would sell that mount and buy a new GOTO eq mount. You can buy the HEQ5 Pro GOTO for $1,400 from Andrews which would be adequate.

A 2nd hand Vixen GP DX with Sky Sensor 2000, or one of the newer Vixen GOTO mounts would be infinitely better and in keeping with the quality of the telescope.

Whilst the Argo Navis is an outstanding product in every respect, I don't think it is the answer in this case due to the inadequacy of the mount you have.

Cheers,
John B

Hi,

Gary Kopff here from Wildcard Innovations, manufacturers of the Argo Navis DTC.

Thanks for the post and firstly thanks to Rumples Riot for the follow-up.

Helping find more stuff in light polluted environments is one of the more
common reasons people purchase an Argo Navis, so you are not alone.

Argo Navis on its own does not directly drive stepper or servo motors.

Having said that, it is commonly interfaced to third party motor
controllers such as the ServoCAT to provide GOTO slew and track capability.
You can read more about the ServoCAT here - http://stellarcat.biz
Though it is used on some equatorial mounts, ServoCATs are most commonly
found on Dobs in the 14" to 42"+ class.

However, many users use Argo Navis in a straight PUSHTO configuration
and its display will guide you to an object so that you can zero-in on it.
You can also point to objects and have it identify them as well as many other
modes of operation I won't go into here.

Some people tell us they actually prefer PUSHTO over GOTO because of
its fast, quiet and highly reliable operation.

One nice thing about Argo Navis is that you can port it from one mount to
the next. For example, if you decide that one day you would really
like to buy a different telescope, you can retain the Argo Navis, the cables
and often the encoders and simply purchase new mount hardware.

A lot of people also tell us they like our level of support and for some, that rates
highly in their purchasing decision.


Best Regards

I agree with John DJ i no you and adding more stuff to that mount is not the way to go. I would go a new mount with goto and autoguide port. Because down the track you will be ableto do photo work with that scope.

Thanks for the replies, guys. Guess it looks like I need a new mount, and if I have to buy a new mount, then it will be way too expensive to go Argo Navis as well.

I could get the HEQ5 Go-TO from Bintel for $1799+ (which is already over budget). And if I was to just get the HEQ5 + the Argo, it would be $2000+ in total.

Here is where the "Astronomy saving fund" begins!!

Hi DJ,

The Argo Navis would give you an infinitely better and more powerfull database of objects than what comes with a standard "GOTO" mount. Further, the Argo Navis is a "Digital Telescope Computer", as opposed to the other systems which are essentially "object locators" only. It's also worth noting that the Argo Navis unit is completely portable from one mount to another, so you only need one Argo Navis controller to accomodate several mounts. Don't assume that you don't get much extra for the couple of hundred more dollars the HEQ5/Argo Navis option would cost you. That couple of hundred extra dollars buys you a heck of a lot. It all comes back to how much you want to spend. You get what you pay for. FWIW, I wouldn't think of a mount less than the HEQ5 for that telescope. One of the Vixen mounts or a Losmandy GM8 would be a far better option, if you can afford it, for imaging with that scope which it is very well suited to. The Argo Navis can be fitted to any of these mounts easily, if that's the route you want to take.

Cheers,
John B

Thanks John. Well, all these options are out of my current budget, so I guess I'll be sitting on my *** for a while, till I can save some more $$$ for this. I'll have to find stuff in space with what I have for now. I'll check out Starry Night, then look up and try and figure out what's what.

Thanks again.

Hold on, are you telling me that the Skywatcher HEQ5 Pro V3 GO-TO, has a less powerful database of objects than the AN?

We would maintain that the Argo Navis database has more extensive coverage,
accuracy and depth than any DSC or GOTO system currently on the market.

Keep in mind that a lot of the customers we attract are among the most
dedicated, hardcore of observers, many of whom will own large aperture scopes
with plenty of light grasp that can go deep.

Some of these go looking for objects like UKS 1 visually - an impossibly
low surface brightness object.

For many other customers, particularly those with more modest aperture
scopes who rarely get the opportunity to get under good dark skies, they
are therefore usually constrained to observe the popular Messier and NGC
class of objects. The good news is that Argo Navis provides for better
coverage of these objects as well. For example, I spent an entire year of my
life revising and correcting the NGC catalog as it is seen in Argo Navis today.
By way of background, few amateurs often appreciate the number of historical
errors that had crept in over the years in this famous catalog. It doesn't
mean our revision is 'perfect' either, but it certainly has far less errors than
most.

Argo Navis has equally good coverage of both southern and northern skies
but in that regard, its southern sky coverage compared to many other
products is superlative. For example, it has the best coverage of objects in
the SMC and LMC out there, largely because we were able to use as a
consultant SMC/LMC guru Andrew Murrell and sometimes it was a case of
packing the scope and looking for ourselves.

There is absolutely no doubt that there are many commercial systems
available that provide sufficient coverage of the sky to keep many enthusiasts
occupied and happy for a lifetime. We cater for those people too.
However, we also cater for those that like to venture far off the beaten path
of the usual Messier and NGC's. Even then, we come across observers who
are interested in even more obscure stuff that still is not in the database. However,
we cater for them too with our powerful user catalog feature that allows
the observer to download their own object entries and observing notes
which are then retained in FLASH.

If you are at all interested in astrophotography, consider the most
solid mount you can afford and even then expect compromise.

If you believe that, at heart, you are more likely to be a visual observer,
consider purchasing the most aperture you are comfortable with as
far as price and portability and still expect a compromise.

Should some time in the future you make a decision to purchase an Argo
Navis, then we would be delighted and believe you have then purchased
a system that does not compromise in what it delivers.

As Gary points out, by a large margin. Like comparing a 1950 model Morris Minor with a 2007 Lexus.

The Argo Navis is in my opinion easily the best digital telescope computer system currently available to the amateur astronomer. Unfortunately it is wasted fitting it to your present EQ3 mount.

I have two Argo Navis Units. One as a "push to" system on my 10"/F5 dob and the other as a "GOTO" system with Servocat on the 18" Obsession. I will never own another telescope without one.

Cheers
John B

Thanks for the info Gary. I actually like the idea of push-to as opposed to go-to. Dunno why...gives me feeling of finding what I'm looking for. However, the fact still remains, that I need more mulah that I was expecting! So, I'll start slow...mount, then AN...then hopefully no more!! LOL..like that's ever going to happen!

Really? I'm not sure this one has an autoguide port. It's not the GO-To Version.

on my heq5 pro the connection for the serial cable goes to the synscan hand controller, or is there a cable that you can plug straight into the mount head?
