LX850 12"
      #5734761 - 03/15/13 07:32 PM Attachment (169 downloads)

I've been lurking on the LX850 forums for awhile now with nothing to post. But now, the LX850 I ordered finally arrived and I've already got one night of use with it! I donít have too much experience with astrophotography, so I was excited about it. I was hoping the mounts features would get me imaging more quickly than if I had to do everything myself; and with more confidence than if I'd done it myself. Rather than figure out how to use the mount under the night sky, I read almost the entire instructional manual while I waited for the mount to arrive.

The box they pack the mount in is huge and just looking at the size of it reassured me the mount was well protected during shipping. One thing I didnít expect was how heavy the mount is out of the box. They attach the DEC counterweight to the mount at the factory that adds an additional eight pounds to lift up on top of the already 50lb mount. A quick fix to lighten the load is to remove the 8 lb counterweight while it's still in the box and lock down the clutches so the mount doesn't flop around when you're lifting it onto the tripod. Donít kid yourself, the mount is still heavy. With the mount in place on the tripod, the counterweight shaft and counterweights thread on. This can be a time consuming process since you have to thread each counterweight on rather than slide and lock it in place like my last mount. This is a small price to pay to making astrophotography so simple. One thing I really like about the LX850 is the saddle plate design. It lets you use either a Losmandy or a Vixen style dovetail by simply reversing the saddle plate-locking rails. This makes using my other OTAs with this mount a possibility without additional equipment. Connecting the control panel was also a bit of a pain since you have to route connecting wires to the RA motor through the mount. It was quick to do and soon I was attaching the ota. Lifting the 12" ota wasnít too difficult and it attached to the saddle plate with ease. I was almost done setting up the mount.

When the mount was fully setup and balanced, I powered on the mount and ran the one star alignment which has you center Polaris and one additional star which the mount chooses. This was quick to do and from this point on, the starlock guide scope did most of the work. The first thing I noticed when it slewed was how quite and smoothly it slewed. No more Meade coffee grinder sound! My object slews were spot on putting objects in the center portion of the DSI III with high precision. I was surprised on how transparent the starlock operated. It never asked me to center nearby bright stars, select a guide star, or enter an exposure time; it did all this by itself. Finding targets in the sky was always troubling for me as previous mounts usually didn't put the intended target on the ccd. But with Starlock, it didnít miss a target. I donít think I could ever go back to a non-starlock equipped scope and have so much fun finding objects. I slewed around the sky for a while finding objects before settling down to start taking images.

To use starlock at its full potential, I first needed a better polar alignment so I ran the Automatic drift alignment routine. Itís a first of its kind as far as I can tell. Usually my manual drift alignments can take 30 minutes or more before I'm confident I have a good alignment with no drift in 5 min. A lot of people I know are too intimidated to learn the drift alignment process, so I know the LX850 would be perfect for them. Many people already know drift aligning is easy once you get the hang of it, its just time consuming. With the automatic drift alignment feature, now anyone can do it. Starlock first slews to and locates a southern star and begins imaging. It can't make the needed mechanical adjustments to the mount required to refine your polar alignment, so instead, it tells you how many turns of the azimuth knob are needed to get you better aligned. Next, it slewed to a star in the east and did the same thing, telling me how many turns of the latitude were needed. It took about 15 minutes to complete the process which is much faster than I can do manually. This is a big time saver and another great feature of Starlock.

I didn't plan on taking really long exposures, but I still wanted to get the best image possible so I trained the periodic error out of the mount by running the PEC training routine. I slewed to a bright star on the equator and Starlock began recording the stars movement. I did the training three times total to get the best results which took about 20 minutes. Since the LX850 has permanent periodic error correction, I won't have to do the training again for awhile.

The LX850 has another feature my previous mounts didn't, its called Automatic guideRate Calibration or ARC. This feature improves the starlock guiding performance by optimizing the aggressiveness of the guide corrections. Since the magnitude of the guide corrections are partially dependant on the localized seeing conditions, this is a great feature that was added by Meade. And again, it's automatic.

As you all know, there's a lot of steps required before you start imaging. The great thing about starlock is that it makes them all automatic. So instead of me squatting on the ground looking through an eyepiece for 30 minutes drift aligning, I'm doing other things.

I finally got to the imaging part and it was only 10 pm but the clouds were starting to roll in. I slewed to M101 using the hand controller and one minute later, it appeared in the center of my ccd sensor. I was excited, starlock was already at work. I refined the focus on my camera and started imaging for five minutes. The first image looked good so I kept imaging, waiting for a bad image to appear. Surprisingly it never appeared and I was happy with the results. Not bad for my first image with the LX850!




The mount was handling the 5 minute sub frames well, so the next question was can it do 10 minute subs?


The stars are a bit bloated. If I knew how to process the photos, I'm sure I could get better images but for now I'm happy. Hoping for more clear nights!

If you have as little experience with astrophotography as implied then as a first attempt at 2400mm those pictures are literally shockingly good. Seems that all you need to work on is the focus, calibration and processing techniques. I'm impressed.

Thats a cynical view. Give them a breather, I think they are on to something here.

I can also see the same tech being introduced to a lighter weight class mount for short focal length imaging.

2400mm is not a joke and the elongation is minimal. Could even be due to loose camera, collimation, wind etc...

Its also not enough to cause trouble after processing. If you want perfection buy an AP or SB mount. For point here dummy operation you get an lx850. Different target market. Price is also a matter what the market will accept so lets not get into that argument

Hilmi,

For automatic, I agree. Pretty amazing at 2400mm. The first image has some elongation the others are much better. I wonder if you did the aggressiveness routine at each target you'd get better results.

I bet after a few nights you'll be imaging like a pro .

Seeing conditions, wind, mole people. These all can cause issues.

These things are shipping and starting to get into the hands of more and more people. Not all of them could be a Meade spy. I suppose it is safe to give it all six months to shake out and see how things are going. How is Meade doing as a company? What are people saying about their LX850's now? Anything breaking? Once satisfied you can make an informed decision.

I for one am encouraged by what I see. I think the post is legit especially when you compare his experience with Glens.

Tony will have his next week and we'll have a third report back. Not everyone is on Jason Ware's level and I think reports from people that are giving AP a try are worth more than people that are advanced/experts in that regard.

I'm awaiting delivery of an LX850 mount (purchased at retail). I hope that when I start posting about it I am not accused of being a shill. For one thing, plenty of folks know me and know that I have no brand loyalty whatever (especially to Meade; haven't owned any Meade gear for years) and have no commercial relationships with anyone in the industry. For another, it would be highly offensive and not the kind of thing we want to see on CN.

-edit- In other words, the poster who started this thread has something to say which is of interest to many of us. Let's permit him to speak.

Thanks John!

I have been waiting months for user reviews for this line of products, and it is frustrating to have to read through comments and bad mouthing by people who haven't even seen or touched these.....

Thank you to the OP and anyone else who has used these products for taking the extra time to post pictures and hands-on comments, it is really and truly appreciated...

I am so excited to see more actual user reviews and first light reports.....I'm certainly not a meade 'fan boy' I am just rooting for them as a general astronomy fan, as I think new technology and competition can only be a positive thing for the community as a whole....success and innovation builds on itself, so it is kind of odd to see some people seemingly root for a Meade failure...at least to me.

Please keep the pictures and reports coming, guys! It is fascinating to read the reports (good or bad) of ACTUAL users.

A million thanks,

Mantis

You may want to play with the auto calibrated RA and DEC values. I find that the auto set may be a bit too aggressive if you do a good job of training the PE. I am using a production mount now and the RAW PE is around 6 arc seconds. Starlock training of the PE is not quite as good as PEMPro because its just an average, PEMPro does a Fourier analysis. After generating the values watch a star in focus mode with your camera and back off if it over corrects. I am using 10% for both RA and DEC which means I have a very good polar alignment and Starlock isn't having to do much work since the drive is running so well.

Not all mounts coming off the line will be that good but no matter, with training you can get to around 5 arc seconds which is no problem for Starlock guiding.

Give us some feedback on the auto polar alignment, I didn't do much testing there, I generally use PEMPro for that.

Ok where do I start.

As a beta tester you haven't tested those things? You are coming right out and saying that the built in drift alignment, Starlock assisted PEC training and auto rate calibration routine are not good enough for you? What is the whole point of this mount again?

Also you seem to imply that Meade has sent you a good mount and that everyone else shouldn't expect to get near 6as native uncorrected PE?

Interesting. I have no doubt that Meade would make sure to hook you up with a choice mount and OTA. That just makes sense. However I can't help but wonder what the others here *recieved* received.




*fixed it for you*

While I don't think that this is a Meade employee trying to pass themselves off as a genuine end user, it does however read like someone who has a special relationship with Meade (beta tester) and wrote out this mini-review and got a thumbs up from Meade to post it. Obviously I am in no position to know either way but I kinda agree here. This seems to be a dual purpose first light report.

Also while everyone has to post for the first time for some reason or another, seems suspicious that this users has only two posts on CN and both in this thread. Just sayin'..

Not trolling just providing a reality check. Before someone pays money for the honor of lacing up their Nike's and drinking the cool aid, I think a little caution is in order.

If I had the intense curiosity you display about a piece of gear I'd either spend a lot of time reading posts about it or go ahead and acquire one to find out for myself. Merely talking about a mount you've never used isn't going to increase knowledge about it, neither yours nor that of anyone else.

In fact, it turns out that I am quite curious about this mount so I've been reading lost of posts, and have ordered one. That seems to be a more productive use of my time and resources.

You aren't in a position to presume to have knowledge regarding what shoes I wear or what beverages I consume so I'd prefer that you be silent on those issues, too.

p.s. The plural of "Nike" does not have an apostrophe in it.

p.p.s. The correct spelling of "Kool-Aid" is Kool-Aid.

So if I am curious about something I should just buy it and see for myself? That is an interesting philosophy.

I have been reading quite a bit about the mount since the LX800 was announced. I am still waiting for something that convinces me either way.

I suppose $5,999.00 is nothing to you. Must be nice to be able to buy one to see if it will work out for you or not.

Thank you for correcting my spelling and punctuation. For someone this uptight about someones word usage and analogous choices, you don't seem to be very picky about where you spend your money.

Good luck.

Sad to see a thread reduced to pointing out incorrect spelling and grammar. I think both sides have a valid point and while the delivery of those points could be made in a more productive way I don't think attacking each other and virtual high fives is the way to go.

Lets please get back on topic.

This was an interesting write up on the LX850 and 12" OTA. I wouldn't mind hearing some experiences with the visual aspects of this new F/8 OTA. I am sure it will be a while before anyone could provide apples to apples comparisons between the RCX F/8 line. We also need to get one of these up against a 14" EdgeHD for visual. Yes I know that most people will not buy these OTA's for visual, however I think that once in a while I might be in the mood to put my eye to an eyepiece.

Edit:

And yes I've had the 12" for a few months but honestly I have yet to look through it except with a target eyepiece for alignment. I was spending 99% of my time putting the mount through more than its fair share of tests and staying up to 2-3am every night (when I had clear skies). Hopefully my experiences and reports to Meade has led to a superior product that we all can be proud to own. Not having a production mount I am just as curious as others to hear back from others.

Now it is boxed up while I wait for my 14" to ship. *shakes fist at Tony*

My only question is why are you concerned about other member's decisions? Meade hasn't sent out an armed assassin to potential mount owners and forced them to spend their 6K on their mount. I imagine that someone spending that kind of money has more than likely read through the myriad posts about Meade's mounts. If, after their research, they decide that they want the 850, it's THEIR CHOICE.

My only question is why are you concerned about other member's decisions? Meade hasn't sent out an armed assassin to potential mount owners and forced them to spend their 6K on their mount. I imagine that someone spending that kind of money has more than likely read through the myriad posts about Meade's mounts. If, after their research, they decide that they want the 850, it's THEIR CHOICE.

I am fixated on this mount because this mount is on my short list of considerations and I wasn't around during the teething phase of the Losmandy Gemini 2 which had just as much heated discussion. Nor was I around when the Meade RCX had its issues. I also believe the Celestron CGE-PRO had plenty of problems when it was first released.

Do you really not get it or are you just being obtuse? I have given no warnings that the LX850 will have problems. I don't know or understand why there is a repeated attempt to put words into my mouth. Please quote me where I claimed the LX850 is a piece of junk and will fall apart or cease to function.

What the heck is wrong with you people? Meade released a mount that LITERALLY fell apart. The Starlock, which was the whole point of the mount, DID NOT FUNCTION. They had to recall the whole thing. Now, because of a few posts by Jason, and a new member who registers to write a glowing review, everyone is lining up to defend Meade. Jason, who is a beta tester, who admits he didn't test some things and asks for people to report on it. Jason, who is a beta tester, who uses PEMPRO to get things set up instead of the built in functions that are a PART OF Meade's marketing on this product.

You know what? I'll go on about my business then You guys can throw your money at Meade if you want. Don't wait another second. Click that order button now! I'll get back to you in six months. Lets see how things went.

I vote for starfield, uncalibrated and unprocessed. Guided by starlock of course.

If anyone is brave enough to open up their mounts, I'd like a shot of the motors/worm block as well.

Ed is correct. CN has a bad reputation for this. Folks leave here and join Y! group which is a much more favorable forum for open discussion.

Negative comments by people who are using the equipment in question are very valuable, so are positive comments.

But negative, or positive, comments from people who have not used the equipment are of no use at all. This applies particularly to comments that attack the honesty and integrity of people who are reporting their experience with the equipment.

If the equipment works as advertised the negative comments will evaporate. Meade failed at the launch so they must shoulder some of the responsibility for the negativity.

If the equipment works well as is supported by Meade with spares, this will be game changer for many. Compare a Celestron C14 Edge HD on a CGE pro to the Meade LX850 14". Just $1000 difference with the guider and software integrated and only because Celestron dropped the price of the package $1000. . It just has to live up to the expectations and have replacement parts available. Integrated solutions are only good if the integrated parts are replaceable.

Malik, Are you accusing the beta testers of lying? Because that's what it sounds to me that you are saying. If you have evidence of this then you should post your evidence. If not you should apologise.

I'm sick and tired of all these insinuations and half veiled allegations. If people don't trust beta testers to give honest information then they should say so so that the testers do not waste their time posting on CN.

Not at all; beta testers are bound by different covenants, that's all. If you look back, it was partly the beta testers that led to the demise of LX800; how could they have signed off? Regards

Im not so sure its that simple.
As per prev posts, the beta testers are under NDAs,
hence cant always give honest opinions on whats going on,
( as it may get fixed pre release ).

Its only after general release to the masses
that the warts ( if there are any ) can be openly discussed.

Neither Jason or I were beta testers on the LX800. I sure hope you don't include me in that. Have people forgotten that it was me that brought all the problems out in the open that probably hurt Meade quite a bit? You could almost hear the cussing taking place in Meade HQ directed at me. I don't know who the original beta testers were either and I agree they didn't catch anything.

If you hear me say anything good at all you can be assured it is 100% true. If I say something negative you can be assured it is 100% true. If I say nothing at all it is a percentage true.

1) Star fields (Something with stars from edge to edge)
2) 45deg up & 1h either side of flip.
2) ISO 800
3) Starlock guided
4) RAW uncalibrated frames

When assessing the results I would recommend that we clearly separate the mount assessment from the optics assessment.

One more request: logs (un-guided) for about 3 worm periods, to see the mount's mechanical performance isolated from starlock guiding.

Frozen.kryo,

For the data you are looking for, it is better to use PEMPro or something similar. Because that will also tell you how smooth the PE curve is. That would tell you a lot more than looking at how streaky the stars are.

Thanks

CCD inspector has a trial and will allow you to test quite a bit with regards to the optics. PEMPRO has a trial as well and will allow you to test quite a bit with regards to the mount. Both of these programs are not that difficult to use.

I'd be interested in seeing the following on the production units.

Starlock assisted PEC. How well does it work?
Starlock assisted Drift alignment. How accurate is it?
Starlock auto rate calibration. How do the reported values work for you?
Go-To pointing and HPP. How accurate?

Long unprocessed .fits format exposures. Minimum of 10minutes.

Post screenshots of the PEMPRO screen and the ccd inspector screen. Post log files for Alph. Speaking of whom, where has he been lately?

Now with the exception of logs for Alph, I've done everything else on my beta non-production unit. I have those results. Would be nice to compare with production results to see what if anything has changed.

I am still around just staying away from psycho talk. PHD or MaximDL autoguoider logs would be very helpful in evaluating differential drift/flexure. The logs should be recorded with the main camera when the starlock is autoguiding. Simply set up your main camera for auto guiding and disable the guider output. To make the data analysis easier, align your camera with RA and Dec coordinates. For the most accurate analysis the camera angle should be known.

Naw, no worries. Just enjoy your new toys!! I don't like the idea of you or anyone else feeling the least bit of pressure to provide immediate feedback. When you get the hang of things and have some free time go ahead and do some testing and if you are inclined to report back to CN, that'd be great too.

You have waited a long time. You should get to enjoy life.
