I just had to try it, I put the AT10RCC /Lodestar/ Borg50/ D5100 combo on the little 10 pound ZEQ25GT tonight.

I used all the counterweights I could muster,two 11# weights off the iEQ45, the 9.8# ZEQ25 weight and a 3.5# weight from my Cube Pro. And it was still OTA heavy, needs another 9.8 to replace the 3.5.

So 35 pounds of counterweights on the shaft, 32 pounds of OTA for about 67 pounds of total payload on the Z-Balanced mount.

Does it work?

You be the judge. This graph is a train wreck compared to a normal load on the mount. But, the mount is really, really stable, even with a payload of 67 pounds (32 pounds not including weights).

Let the naysayers repent, this design works. That's my story, and I'm sticking to it.

Cheers,

Paul

Well now I'm waiting for Smart Eq Z Pro for an even lighter and smaller mount :)

Impressive results....

The graph looks nice, but an image trough the 10 inch is really what counts ...

would love to know how long of an exposure you think you can get reliably using that setup.

if it can handle that weight well, you could probably put the 9.25" edgehd or maybe even the 11" on there. o_O

would love to be able to put the 11" edgehd with hyperstar and a dslr without having to go out and get another mount.

I have been looking at light wt mounts that can carry up to and including my C9.25HD. This one could be a contender.

@vdb... it's cooking.

@ohato0... I just did that for fun, that much weight on a 10 pound mount...ouch. I did get some 4 minute guided exposures, but I certainly wouldn't make a habit of it. The AT10RC normally hangs on the iEQ45, comfortably.

@Mike... I don't know about a 9.25 carbon fiber, maybe? But it's downright scary putting the AT10RC on the little mount, I kept waiting for it to fall over..lol.

Clear skies all,

Paul

Had no way to shoot flats (OTA too big for my laptop or iPad screen) so this is all I got........

How could you!? Torturing that poor little mount! What did it ever do to you? For shame! And, like a horse, it tried no matter what you threw at it...limping along under the strain of that great big scope. But it would not buckle, it would not fold. It had HEART! Heart I tell ya!

Kinda cool!

@ Edmond... you'll have to fight me for the ZEQ45 or ZEQ110..:)

@Jose, thanks very much, but that's a really rough process on a very dim object, it's like pulling teeth to get data on the Fireworks...:) I hate to stay up until dawn for flats, but I'm going to have to, or buy a EL panel :(

@Paul... now you made me feel bad. The mount did look funny though, kinda like flea carrying an elephant...lol.

Cheers all,

Paul

Not bad for a mount that costs $1500 and weighs 40LBS...

...of course this mount costs $850 and weighs 10LBS.

It really is amazing what this mount can do.

Great image Paul!

I noted you have an IEQ45 mount. For a given telescope, say your Stellarvue 90 Raptor and the same guidescope/guiding camera combo, which mount performs better, your IEQ45 or your ZEQ25GT? Wisdom points to your IEQ45, but your reviews about your ZEQ25GT say maybe other history.

Thanks

Fantastic yet not surprising after spending a few weeks with it now just need more clear nights.

I'm finding it hard not to take great pictures with it here is the one single 4minute guided light i got before some clouds set in no darks just edited the single RAW file :D

Ok, that is it. My cg5 is history. I'm getting one of these. I am waiting for the 2 inch tripod variant to come in. Would rather carry a few extra pounds for a bomb proof undercarriage. Ioptron says they should be in later in June.

<-- what he said....:)

Jesus, my particular iEQ45 performs better, but only because I have installed a TDM encoder on it. But in stock configuration with that setup, the ZEQ25 is smoother all day long and much more forgiving when autoguiding...it's basically plug n' play.

Chris, nice m51, now you're just showing off, a single sub, you stink....:)

Dan, you could do a lot worse...and the 2" only adds about 6 or 7 pounds to the total package.

Cheers all,

Paul

Dan, are you putting your 1100 Edge on it? If so let us know how it goes. I've been thinking of doing the same thing.

Other than as a stunt, no. It would be interesting to see how it performs, but it just seems dangerous to me!

Now, my es 127 cf might work well enough for visual. Astro with my sv 80 is really the target matchup. I want bomb proof no hassle tracking for that.

I'm keeping my eyes out for a heavy version of the zeq. If they came out with something designed for 45+ pound capacity, the Losmandy G11 would finally have some real competition. There is not much to choose from above the Cgem and below the Mach 1.

I already put it on my Christmas list, and I'm hoping it will have a precision Renishaw type encoder option too....;)

The 45+ with the encoders is my next mount and if it's G11 pricing, it would be a real nice item.

Paul, did the encoders make a huge difference when guiding (with guidescope) your iEQ45?

Thanks,

Paul

Me 2. I found that my CGEM is at its limit at 35lbs. If I can get a ZEQ of 45lbs version with less money than G11, I'd go for it. I was thinking about upgrading to G11 and luckily this comes along and I can hold on my plan for a while.

So Paul ... hypothetical situation.

Someone steals your iEQ45 and your ZEQ25. You need an imaging mount and you have about 35 pounds of gear all in. You want to be able to image with a variety of scopes including long-ish focal lengths like a C8. I offer to give you, free of charge (so price is not a consideration), either an IEQ45 (no encoders) or a ZEQ25. Knowing what you now know about the ability to overload the ZEQ25, which one do you take as your only mount going forward and why?

I do not have the ZEQ 25 yet, but would like to see a 60 to 70 pounds version.
