What does HyperTunes mount mean?
      #4399153 - 02/20/11 11:49 AM

When Reading some post from other people. I noticed some of their signatures wrote about their mounts they have, like example Celestron CGEM ( hypertunes by ___) I really don't understand what does hypertune mean.

Thanks for explaining

Basically a hypertune is a tear down, regrease, and adjustment of all gear to gear surfaces. For some, that is all. Others go to the extremes of honing or polishing internal metal surfaces.

It seems to be a bit of hyperbole, honestly. "Cleaning and Regreasing" doesn't sound as sexy as "hypertuning" though.

The original hypertune included the honing or polishing internal metal surfaces, it was one of the most important steps. It also included replacement bushings and high grade grease.

In my case, it also included some sanding/polishing and upgrading of ring bearings and spacers (oh, and removing some rust that came with the mount). I agree Eric, cleaning and regreasing isn't much of a "hypertune" - more like periodic maintenance. Depending on any specific issues with the mount (stiction, balance issues, etc.), Hypertuning can be a big help. Deep Space Products offers it as both an in-house service and a Do-It-Yourself kit ( http://www.deepspaceproducts.com/hypertune.html ).

Steve Forbes offers it for iOptron alt-az mounts, where it is much more than a regrease and adjust: http://www.trapeziumtelescopes.com/

What it means is that someone has opened up the mount and messed with it. That can occasionally be a good thing, usually something that has no practical effect of anykind, or, unfortunately, sometimes a disaster.

LOL Many people who use a mount for some time and then pay ??? for a hypertune say that they notice little if any difference. Although some swear by it, but that just may be in their heads

For those of us who've had actual mechanical problems with their mounts, a hypertune does make a significant difference. This is not a golly, what can I spend some money on this month expenditure. In my case, I had a choice. Send it back to Celestron for warranty repair or send it off for basically a rework and rebuild. I chose the later for a number of reasons, most importantly getting the mount back quickly. At the time I sent my CGEM to DSP, the wait time for Celestron warranty turn around was a number of weeks. And there was no guarantee that your mount was going to be 'fixed'. Was my mount better after hypertune? Undoubtedly. Would I have received a rebuilt, improved mount back from Celestron? Probably. I really can't speak to their speed and quality of service so I'll leave it to others to voice their opinions and experiences.

I'm sure others will chime in here. If you have the tools, time and mechanical ability a DIY kit is ideal. If not, DSP offers the service with quality work.

Sorry but I've also hyper tuned my own cgem and there is a world of difference. Before the ra axis would literally stick at certain positions and was generally difficult to rotate. After I started taking it apart it was quite evident where the two problems were. One was one of the bearings was extremely difficult to turn by hand while all the others turned freely. This was due to too much grease packed in the bearing. The other problem was the actual "brass" gear housing rubbing against the housing at certain locations and sanding that slightly fixed that. The axis now can spin several rotations freely with the clutch disengaged when pushed by hand once. It would be obvious to anyone who saw before and after behavior that a "hyper tune" made a near unusable mount to one better then most new ones.

There is an adjustment on the Dec & RA shafts to place
the gears closer together (on an EQ6 mount & probably all mounts)
It is very important to have it right otherwise backlash
problems will stop auto-guiding from working.
That was my case until I had it fixed.
That is a hypertune in my book but you could also put
in good quality bearings & grease.

In my case, I actually DID send it back to Celestron for warranty work. It came back "fixed" but with the exact same issues (sticking in RA and DEC axes - unable to balance with resulting impacts on tracking and autoguiding). Celestron "offered" to look at it again, but at my expense.

There are some folks out there who a) have never done it, b) don't understand it or c) have staked out a position because they "know" better than the rest of us who have actually made our mounts better as a result. I'm sure there are disaster cases out there too, folks like that tend not to want to advertise their outcomes though. In the end, it is something that you have to undertake with your eyes wide open, especially if you do it yourself, and with a full understanding of the potential implications.

The bottom line is that there certainly seems to be enough empirical data to suggest that Hypertuning improves the performance of a mount - I've certainly read far more accounts where it has improved the mount rather than having no effect, or a negative effect (and with all due respect, I doubt very seriously if it's some kind of mass delusion suffered by folks who are tired of fighting their mounts). But anyone contemplating it (or passing judgment on it) should do their research, not take the word of any particular individual.

After wasting 3 weeks with C tech support on a brand new CGEM, I sent it to them as they requested. I included a list of things they said needed to be looked at after the 3 week communication and info gathering we did together via email.
They sent a warranty receipt back with it saying they updated the hand control. Not one thing on the list we had mutualy determined needed attention was listed on the warranty receipt. The mount performed worse than originally received after service and had to be replaced by the dealer.
The new mount replacement was substantially better than the original but was impossible to balance properly as the axis would not turn freely. That strained motors and gears.

I sent it off for a Hypertune and could not believe the improvements of the mount I received back. Balances easily, no straining motor sounds, no gears jumping and a pleasure to use. I can now run loads within Celestrons own specs without problems.

Do not question the validity of a properly performed Hypertune if you receive an inferior example of a mount. I guess you have to get the manufactures assistance for warranty. But sooner or later you get tired of trying to get help and realise there is very little quality control involved with mediocre, mass produced mounts.

I for one am tired of hearing not only that there is no need for a Hypertune,or that it could mess things up, but that the manufacturer will make it right, and mostly from people that at one time I respected their opinion. Now I don't. I have never personally heard or read of a Hypertune that turned out to be a " disaster ". It can be quite beneficial if needed, and it is not something the factory is willing to spend the time doing under warranty.

If you receive a good sample of the mount, congratulations, that is how it should be. If you do not, seek warranty repair or return to the dealer. If you think a Hypertune could help you, do your homework as you should.

My CGEM is now a pleasure to use and the only problems I have encountered........ are self inflicted.

Hi Mak7 - I was lucky in that there was an expert in Melbourne
who did a hypertune for me.
Without that I wouldn't be able to auto-guide.
I can now auto-guide with a light 4.5" Newt.
Now I will transfer the guidescope to a heavy 8" Newt & try it.

empiracal data? not from what ive had first hand experience with. I have bought 3 different used mounts who have all had it done. NEVER again. If I see one thats been hypertuned i stay away because everytime they're major pieces of junk. the last one i got was a LXD55. the tracking is much worse than stock (i meassured with PHD and owned one stock), the polar scope is completely trashed, the DSP high-res encoders ruined, and the worm blocks are stripped in the center hole. and that doesnt compare to a LXD75 i bought i few years back. I've owned them stock so i know how they're supposed to perform.
as well I've done it myself to a CG-5. re-greased, new bushings, new teflon spacers, lapped the worms and polished the internals. maybe 1 arc sec better PE after all that, which is pretty much in the error zone anyway.

the best most reliable mount ive owned is my current atlas, I am convinced this is because the origanl owner never tried to "soup it up."

now when i hear "hypertune" i cant help but think of a 16 year old putting neon lights and a fart can exhaust on a honda civic. or billy bob installing traction bars and cutting the catalytic converter off his new camero.

from my experience its for the most part not much more than an internet meme. maybe in the earlier production runs with synta glue or just a mesh adjustment it makes or made a positive difference. never owned a CGEM but if they're that bad from the factory i dont think i want to.

here my stock atlas in 10 degree weather.

Well, we can look at the responses on this thread (although that's a pretty limited sampling), five who have had it done (or did it themselves) and are happy with the outcome, and one who purchased "hypertuned" mounts who isn't.

This sounds a bit more serious than a Hypertune. In fact, no where in the Hypertune process do you even TOUCH the polar scope, let alone the encoders. I think one needs to be careful of how the term "Hypertune" is used. Hypertune is a registered product of Deep Space Products. It's easy enough to fall into the trap of using the term like one might say "I xeroxed that" when you really meant to say "photocopy". Kind of like souping up your car, or bike, or computer, or...... mount - generic terms don't necessarily imply standards, just a loose intent.

Glad to see it made some difference, but quite frankly - why would anyone bother if there was nothing wrong with the mount in the first place? Let's face it, Hypertuning is NOT cheap! Whether or not it provides value for the money (as it seems to have in the majority of cases on this thread) is a personal decision - but there are enough things to throw money at without ripping apart your mount (or paying someone else to) for no good reason!

Hmmmm - so you honestly think everyone on just THIS thread is so "newb" that none of us know any different? Not to say all of the others who have had the service and are satisfied with it?

It's obvious that you've had a bad time with folks "messing" with their mounts, and it's understandable that you've developed a bad vibe with all after-market tinkering. Fare enough. Heaven knows that I've had my bad experiences with products and services and it has colored my view of them. Every informed viewpoint is valuable, and is what helps others to construct their own informed viewpoint. Perhaps distinguishing between "souping up" one's mount, and Hypertuning, would contribute more.

it goes to show a certain number who attempt to do end up with a lesser mount. you do in fact touch the encoders for the meade mounts.

true i am using the term generically.

that doesnt say anything about if its doing any good, let alone a cost benefit ratio. thats merely begging the question. yes the mounts arent perfect, but that doesnt in anyway mean hypertuning is worth a darn in general for every mount. but that is the way its always portrayed on forums. there is such a thing as a placebo effect.

i didnt realize hypertuning was a trademarked name, sorry. if you would like to tally up all the positive experiences with empiracal data, lets say at least before and after PE measurements, their practical effects on the intended use of the mount, and the cost and effort involved versus neutral or negative experiences be my guest.

my personal experience and obviously others is that its sort of a band-wagon phenomenon and generally (perhaps not always) negligible at best.

you hear alot about how bad some CGEM's are from the factory, but you dont hear about all the ones that are fine......i suspect you probablly dont hear much about someone who spent a bunch of money on an already expensive mount and it didnt really do much. or i doubt you'll hear from the home tinkerer that stripped a bunch of bolts and bent the worms on accident talk about it much either.

new people to the hobby want to know if this expensive under-taking is going to be worth it, especially since they usually just depleted their bank account getting the basics in the first place. is it? does it make the guiding better? is it giving better average FWHM from better guiding? what is the reality and the real cost/benefit?

Honestly, no - just responding to the generalization you made on your last post before you deleted it. I'm glad to see that you did, as it really wasn't called for and added nothing to the discussion.

You obviously have an immovable opinion, and that's alright (I'm sure the same could be said about mine). Like I said, anyone contemplating this should do their research and draw their own conclusions - hopefully no one would plunk down the cash based solely on what either you or I alone have to say.

I only edited the comment because it was worded wrong to me. newbs dont know what is solid fact and what isnt exactly, i remember being there. most of the hypertune hysteria ive seen is mere testament and conjecture. and most that ive personally dealt with was neutral at best and often negative. (especially as a used selling point)

also i do not have an unmoveable opinion, its actually easily swayed by solid data and experience.

we may be comparing apples and oranges a bit too. We need to define 'hypertune' to me it means what in the old car tuning days was called 'blueprinting'. Many mounts have their own idiosyncrasies, some are made well but poorly assembled, some need more than a strip,clean, relube and adjust.
Replacing bearings and modifying parts to me counts as a hypertune.
Without replacing worms and bearings the PE is not likely to decrease BUT it may be smoother.

John,
You make a very good point that we have no definition between a Hypertune and some one just attempting a hotrod of their mount.

The Hypertune that my mount received from Deep Space Products polished internal surfaces, replaced cheap plastic bearings with teflon bearings, replaced original ball bearings with ceramic ball bearings, cleaned all surfaces and removed sticky grease and replaced it.

I can only wonder what some tinkerers have done to their mounts and no wonder people are leary of the thought of buying a home done fixer upper.

A Hypertune done at Deep Space Products is a plus, but it would be hard to tell what you would get from an authorised Hypertune kit done by an inexperianced mount owner trying to follow the directions. Even worse somebody that tears into their mount thinking they can fix it.

A Hypertune is not needed for every mount. I think once you know yours has problems and get no real recourse from the factory, the Hypertune is the next viable alternative and can be a great assistance to many of us.

My opinion is that my CGEM was turned around from unable to track and guide to a very respectable mass produced, mediocre mount. I can actually guide it now, and hope to start using it for photography once all things are in place, mostly only my own personal knowledge is lacking now.

OTA tune up? Much less scope there or need as the production tolerances are necessarily much tighter. It used to be common practice in the 'bad old days' to buy a mass produced scope, refigure the mirror and sell it on, gradually improving your current instrument over many years.

Focusers are a popular after sales modification but most optics are serviceable and if not up to spec (no pun) can usually be returned.
Rarely an ota may need baffling/flocking. Sometimes a better secondary mirror may help.
Unless you want to get into the esoteric world of lens design then generally no, ota's are probably best left to the manufacturers or experts.
Suitable test equipment and more importantly the expertise to use it and interpret the results would have to come first.

Also, I'm not sure 'hypertune' is an accurate term (or 'supertune') they both smack of marketing to me rather as 'de lux' has come to mean bigger, not better. Although they are in common usage, generally accepted and understood in the astronomical community to mean 'enhanced in some way'.

Well, the reason I asked is because I am not getting good images of Jupiter on visual with my CPC 11 inch. Jupiter is mostly a bright blob with very little detail. I can barely make out some bands. So I was thinking about sending the OTA off to be "hypertuned" or "super-collimated" or "rejiggered" or whatever the term might be. Thus my question.

I'm not sure how finding a bearing inside a mount that takes a large amount of force to turn by hand, even compared to the other exact same bearings in the mount (this being a CGEM with 6 ring bearings) is not evidence enough that a "HyperTune" was worth it. You don't need a photometer outside to measure if it is day time or night time while you are standing outside do you? These fixes/modifications are quite evident and don't require empirical data to back them up. If I were to claim that this improved my periodic error then yes, I would expect to see some before and after data.

The problem is as I see it is that individuals here are lumping every modification/opening of a mount as "HyperTuning". Just because someone sells you a mount that is labelled as self "HyperTuned" doesn't mean they did a good job or knew what they were doing. They are using the terminology to sell a product that they perceive as an extra feature that can garner more money. When it is "HyperTuned" badly it obviously gives the rest of the people who did do a good job a bad stigma. Some of the "fixes" which have shown drastic improvements mentioned here are for the CGEM which are fairly easy to fix when you know how to fix it or "HyperTune" it and have consistently shown improvements.

I think hypertuned means that the mount has been altered after market to perform to the manufacturer's specifications because the manufacturer can't or won't meet specifications.

Greg,
I think you're pretty much on target. The reason many of us Hypertune our CGEMs is because of its poor mechanical performance, specifically in balancing and tracking. This is typically due to ring gear binding in the housing or a bad bearing. These are not minor problems that work themselves out. Take a look at John's photos of his DIY Hypertune over on the Yahoo group.

I don't think a majority of mounts need a rework and upgrade. Most folks are pleased with their performance. There are some mounts though that do need some significant work to get them running correctly.

Hypertuning is just one more aspect of this hobby that seems to spark a heated debate. LOL. Like every other aspect does not? I find these debates both informative and at the same time, frustrating. Far too often they devolve into FUD and we're left with just another thread abandoned and archived with no one who reads it later, really sure what the 'facts' are.

I'm surprised, I heard a lot about doc clay with meade but I never heard about hypertuning for celestron mounts.

Would a simple worm gear adjustment show the same results?

In this particular case, no. I don't think a simple worm gear adjustment would have improved the raw PE as much as doing a complete tear-down, bearing replacement, re-assembly, re-greasing, and final adjustment has shown here with my particular results. One of my original RA bearings had been throroughly worn and needed to be replaced. As with anything in the hobby, however, YMMV.

I do agree with the interpretation that "hypertuning" can, in some cases, be thought of as regular servicing. But servicing implies the periodic application of basic work and adjustments to maintain performance. The goal of "hypertuning" is to measurably improve performance.

So, whether you choose to embellish the terminology or not, the end results in my case were very positive.

Hi,

In my experience hypertune means that the mount has been disassembled and adjusted to improve performance. But that doesn't mean the mount will perform better.

In my experience a DIY hypertune will degrade the mount's performance.

I tried to hypertune my CG5, why? Because the Dec axis was impossible to balance. I ruined my mount, after a couple of nights the Dec axis was stuck...

I gave up and send the mount to deep space products. I was lucky because the damage I inflicted to my mount was repairable.

After the service provided by deep space products the mount can be balanced in Dec and the PE is much smoother...

My advise is:

-- Don't hypertune your mount unless it really has a problem. In case you decide to do it, send it to a pro
-- Don't do it yourself, really, it is more likely that you will break it!

Cheers,

Jose

If your mount is working properly, ie. to manufacturing specs, hypertuning is unlikely to make it "better".

If your mount is broken or not operating to spec, hypertuning then becomes a repair with maintenance issues resolved as a result of tear down and reassembly.

Warranty work is likely to be hit or miss in terms of actually fixing the perceived problem and will likely take much longer than you want.

Doing it yourself is likely to worsen performance.

If its broken, get it fixed, if it ain't broke, don't fix it.

Does that pretty much sum things up?

Al,

What you described is called worm gear mesh adjustment and I don't think this can be called hypertuning. All owners of GEMs should be able to perform this simple mechanical operation because it has to be done periodically and may require several iterations to get it just right.

Sorry but I've also hyper tuned my own cgem and there is a world of difference. Before the ra axis would literally stick at certain positions and was generally difficult to rotate. After I started taking it apart it was quite evident where the two problems were. One was one of the bearings was extremely difficult to turn by hand while all the others turned freely. This was due to too much grease packed in the bearing. The other problem was the actual "brass" gear housing rubbing against the housing at certain locations and sanding that slightly fixed that. The axis now can spin several rotations freely with the clutch disengaged when pushed by hand once. It would be obvious to anyone who saw before and after behavior that a "hyper tune" made a near unusable mount to one better then most new ones.




I don't think this is hypertuning, I would call it "fixing manufacturing problems"

In my opinion definition of hypertuning should be: "improvements of normally functioning mount which are not part of regular maintenance", so the following can qualify as hypertuning:
-replacing worm gears
-polishing/honing working surfaces
-replacing bearings
-replacing gears like warpdrive for lxd75
-replacing grease by a better one

I recently visited a dealer whom I will not mention out of privacy reasons. They stated to me they end up returning 1 out of every 6 cgems sold. I'm not suggesting that CGEM's are all bad, but their partner factory in China leaves some doubts about quality control. Celestron's pro mounts on the other hand do not suffer these issues. Celestron is not alone. In trying to mass produce a gem on the cheap has caused many problems for several manufacturers. I no longer own my CGEM, but before I had it "hypertuned" by deepspace, it was not suitable for imaging work. (I sold it to save my back in setup). Once the mount was hypertuned, I could image for 15 min with no trails. Before the hypertune, I could get a minute. The pointing accuracy was horrible despite Celestron's superior software to my current mount. I had a choice, spend $300 to get it right, or send it back to Celestron and wait a month and hope it comes back right. I love my Vixen, and I haven't had to do anything to it. After the first star is aligned, every star appears in the FOV of a 12 mm. Unfortunately,despite it's accuracy, the software is lacking and I have to use TheSky, to image many IC's and NGC's that don't appear in the database. It's assembled in Japan rather than China. Now if Vixen would just buy Celestron's software, and Celestron would use Vixen's factory for assembly.......

Sadly Celestron used to use Vixen's factory.. hence the proliferation of Celestron Super Polaris and the like. Guess things got too expensive for them.

vpcirc, I ended up with the CGEM (vs the SXD) because nobody I know can successfully image with a C9.25 on an SXD. Hope I don't get your experience, or a DIY "hypertune" is in my future..

On the factory tripod I would agree on the 9.25. I am wondering now though since I built a concrete pier that seems to be much more stable. I also switched to guiding with finderscope. They rate that mount at 50lbs, but I think 25 lbs would be the safe limit. I was running a side by side setup with a meade 102 and a meade 80, and didn't have any tracking issues. But I think my total load was 21.5 lbs with cameras.

What it means is that someone has opened up the mount and messed with it. That can occasionally be a good thing, usually something that has no practical effect of anykind, or, unfortunately, sometimes a disaster.




Messing with some of these mounts can be a good thing. I think Uncle Rod's advice in the vein of, "let sleeping dogs lie" when it comes to mounts (or SCT or anything else) is generally good advice so long as you are getting acceptable performance out of the mount (or SCT or whatever else).

My own Atlas was bought used and was of older vintage. Last winter it became stiff in the dec axis and I steeled myself and opened it up. It of course had the melted yak glue in place of grease and there were paint chips and metal shavings mixed in with the grease. I assumed that some of this detritus got there during assembly but some might have been generated as parts that were not machined to specs ground against each other. So I polished the parts, replaced the grease, replaced the worm bearings and tuned the mesh.

Messing with my mount paid of wonderfully. It is easier to balance and my PHD graphs are superb. Maybe this spring when the Great Washington Nebula has evaporated I will post a screenshot.

Besides the state of the mount another thing to consider is your own mechanical aptitude and patience. It is easy to foul up things if you don't go slow. As in thermodynamics, quick actions may be irreversible

That's good Blue.
With my EQ6 mount I couldn't get PHD to guide it at all until
I had the backlash adjusted by an expert.
The DEC axis line would go right off the graph
& the RA wasn't much better.
