    Default zeq25 or ieq30?



    Hi,

    I'm looking at a lightweight mount for portable AP use. I already have an observatory mounted CPC1100, but want something to take to some dark skies next year (have relatives who have moved to dark skies in inland Australia, and I'll be visiting monthly next year).

    I've read all the threads I can find on the zeq25 , and the lesser number of threads on the ieq30.

    My goal is to image using refractors up to an ED120. So I'll be generally imaging at a focal length of under a meter.

    The mounts have been out for a while now, so I'm wondering what the consensus is on them currently.

    Is there any reason to go for the ieq30 other than it's permanent pec? Does the zeq25 even need pec? The graphs I've seen seem pretty smooth and guiding should not be an issue if they are all like that.....

    Do both of these mounts connect to Sky Safari now? - I have a Macbook.....

    Alternatively I also use a Windows laptop - what about ASCOM - I've seen reports of issues?

    Generally looking for advice and experiences that would help me make a decision on which of the mounts to select.

    cheers
    Gary

    Im kind of in the same boat. The ieq30 has a heated controller with more options, it also has a locking springless clutch and supposedly has gotten between 3 and 12 arcsecond accuracy peak to peak. I read somewhere that it guides better than the ieq45. Then again it is $450 more than a Zeq25. I ordered a Zeq25 last week and from what I have read, alot of them have overcurrent problems with the encoders because the spring which is used to tension the Dec and RA axises as a clutch can lock up because it is not the right size. I have also read that the Ra axis is wobbly with heavier loads and that the 27lb rating is actually exaggerated. Now these are things I have read from users with issues, so obviously only people with problems will post these things. I am one to see how things work for myself and have high hopes for the little Zeq mount. It does have periodic error correction, but I don't think it is permanent like the ieq30. However, when you are autoguiding you don't really need to use PEC if you have a good alignment.

    I would assume that if you recieve a well assembled Zeq, the ED120 would do fine. I have heard of others using C8 and C9's with good results and these scopes are much higher mag and weight than the ED120. A better way to combat stability is to get the 2" tripod and keep your eyes open because I'm pretty sure the guy who runs ADM is going to be making some upgrades for the ZEQ25. If he makes a longer dovetail mount which allows more contact with the dovetail bar on a telescope then I would suspect stability would increase dramatically.

    If I get a dud ZEQ25, I am going to send it back and trade for an ieq30. That is the plan. Although... I really like how ioptron will allow you to service the mounts yourself or allow you to send them in for repair. As I understand ioptron provides a parts catalog for every mount so that anything is replaceable. This is honestly the main reason I will be switching over from celestron, after they told me they would not replace the worm gear in my cg5 ra axis, I said you know what, I'm done with this company. Bring on the innovators and the dreamers.

    Thanks for the comments. I'm still very undecided which way to go. The zeq25's light weight appeals, but as I'm in Australia, we don't have the luxury of being able to just return things for exchange. Even warranty work has to go back to the US with freight paid by us both ways! It seems to be really hard t get hard data on these mounts. I'd really like to see pe graphs etc to check out guidability.... may just have to make a purchase as an act of faith! But then a friend has offered to lend me an eq6...but it's just soooo heavy. Do you happen to have any links on the mounts that you could list?

    cheers

    Honestly I would stick to vixen and skywatcher just for the sake of customer service in australia. You could take a chance on the eq mounts with ioptron but the reality is that any imported product has the chance of being damaged in transit and if you need serviceable parts, they have to be imported. Flickr: Astronewb2011's Photostream paul has a bunch of zeq25 graphs on his site. Astronomy Australia - Equatorial Mounts for Astronomy seems to be an australian supplier of skywatcher and vixen mounts. Is the eq5 to low on the totem pole? It can't be much heavier than the zeq25 and is probably lighter than the ieq30.

    Hi again,

    I decided to take a chance and have just ordered an IEQ30. I've bought from a local dealer with a good reputation. Will take a week or two to get here. I wasn't able to find anyone complaining about the IEQ30, so I figured that was a good sign. Thanks for you comments. I'll do a full report and post it once it arrives.

    cheers

    Ame keep me posted gary. I have the zeq25 now and there are some things I do and don't like about it. I have some extra cash so I could get a 30 or even a used ieq45 right now so things are up in the air. If you have a good experience with the 30 and I am not feeling like I have gotten my $850 worth out of this mount I may just send it back and trade for an ieq30 myself. The 30 does seem to have some great features along with that higher end hand controller, temp controlled encoder clocks, permanent pec, heated controller, higher load capacity, and it can tell you if the loads on the RA and DEC are properly balanced somehow. The only difference I have noticed between the zeq and the 30 he time it takes for e worm gears to completely cycle. The ieq30 takes 400 rotations while the zeq takes 600 rotations. Hopefully you have received your new mount by now.

    Hi,
    Unfortunately the mount hasn't arrived yet. Had to be shipped from the US and has been held up in the Christmas holidays. I'm waiting less than patiently for it! More than happy to fill you in on my experiences, but not sure if I will have it quick enough for you to take advantage of your ability to return the zeq25.

    Cheers

    Ahh I have 30 days to send it back and upgrade it. If I get clear skies soon I will make the decision early. It seems like a good mount but has some strange crosstalk problems which I am not certain about as I have been unable to test autoguiding.

    The ieq 30 arrived yesterday and looks beautiful. Everything works nicely, but due to weather it will be a while before I get to test its tracking ability. Did you sent the 25 back?

    I just ordered the 25 as I wanted something light and manageable. To offset potential weight capability issues between mounts like the 25 and 30, I purchased an ES Carbon Fiber telescope as it is about 5 lbs lighter than its metalic sister. Hopefully, the additional weight caused by a camera and the like, will come in well within the operational limits of the 25.

    There are always inviting technology bells and whistles as one looks towards more expensive machinery. With me, it's the old "Champagne taste with a beer pocketbook" scenario. Fortunately for me, my wife keeps the key to the candy store :-)
