In addition, how do you think the ZEQ25 will hold up with a Celestron Advanced VX 8" f/5 Newtonian? It's about 27" long and weighs 14 pounds. My primary concern is the wind...

The ZEQ25 weighs 33 pounds loaded.

Mount: 10.4
Counterweight: 10.4
C/w shaft: 1.5
Tripod: 11.0

Specs are here: http://www.ioptron.com/index.cfm?select=productdetails&phid=931ce45f-3778...

I've imaged with a payload of 22 pounds, with excellent results. I really believe the working capacity is greater than stated, but if your imaging rig, OTA and guider and camera is around this weight, I can highly recommend it.

The mount is so well balanced, that with a 22 pound payload and 20 pounds of counterweights, you can adjust the latitude adjuster with two fingers easily. Perfect balance.

I've imaged in wind gusts up to 10 mph, the mount just shrugs it off. Typically, in a string of 15 images, I might cull 2 due to elongated stars...and I'm OCD about oblong stars, I check my images at 100-200% magnification and delete before stacking. Of course, that's with a AT6RC, which is not as much of a 'sail' as a Newt...:)

Hope the info helps,

Paul

Just played a couple of minutes with a Jupiter pic gleaned from the solar system imaging forum to see what Focus Magic could do for planets.

Paul,
Do you think it would work if I put a 10" F6 newtonian on it for visual only? The scope only weighs 9kg (carbon fibre truss), but its very long...

It would probably be okay for visual at that weight, but the momentum of a tube that long might be an issue..?

To wit, I can spin a 4" long pencil between two fingers and control it pretty easily. A 12" long pencil, not so much.

There will be larger versions of this mount available before the end of the year, I'm sure. And I'm pretty sure the next version will be able to handle a 10" or 12" Newt with no problems.

I would wait....

Paul

Thanks for the info. My first plan is to put my new Borg 125SD on it for imaging to replace my Tak EM11 (yes i'm serious)

The money I get from the difference may finance me a bigger version of that mount for my newt.

I'm pretty jealous, the Borg 125SD is what I'll eventually wind up with to replace my 80 and 90mm refractors, and my 6" Newt. Depending on what reducer you use, you've got all the FOVs covered, with an OTA that only weighs 9 pounds soaking wet.

Congratulations Paul, looking forward to some first light reports when you get that setup sorted out.

Clear skies,

Paul

Nice improvement. Have you tried any other deconvolution methods like those in Photoshop "smart sharpen", Maxim DL, Images Plus or Raw Therapee?

I am totally amazed with this mount! For the price point and autoguided exposure lengths. My current mount, the celestron ASGT, I would be lucky to get 5 minute SUBS due to DEC guiding problems. And I also use an AT6RC and cant do narrowband photography because of this. This mount seems like an ideal solution. Any cons to this mount with the AT6RC? Does this mount seem to be an ideal match with this scope? This could be the answer to all my astrophotography problems and its cheap, lightweight, and accurate.

I don't do astroimaging. Never have as I'm strictly visual. I've been scopeless for a few years and plan to get a grab n' go ED refractor this summer to get back into astronomy. As for Photoshop, I don't think my Photoshop 5.5 has an option for smart sharpen. I got Focus magic recently to help restore some old pics for my vintage battleship photographs blog. Just took 2 minutes to see what it could do on the pic in the OP.

The last 3 versions of PS have Smart sharpen options.

Yes I'm replacing a lot of stuff with that as well. I'm planning to put a borg 7870 triplet reducer on it, which gives it 525mm F4.2.

I already have a TS zero power flattener: at 750mm F6 it gives decent image scale but is still fast enough. The flattener with 68mm screws directly onto the moonlite focuser i got from Hutech. The focuser may add a little bit of weight, but its much better than the original drawtube style focuser I think.

Very nice reducer, I have it along with the flattener and the .85 reducer, all good equipment. Borgs are like Legos, with the right components you can build almost anything..:)

Not yet, except not enough clear sky. I did replace the upper vixen rail with a ADM Mini Dovetail, and put a Feathertouch Lightweight focuser on it to minimize the weight...shaved about 2-3 pounds off the total package.

You will need an additional counterweight to balance.

Cheers guys,

Paul

Thank you Paul. I read in another forum that you are a bit hesitant to recommend the ZEQ25 for 8" SCTs... Based on what you said here, has your opinion changed?

I'm just considering the ZEQ25 over the IEQ30 due to cost savings and weight. I'm going to see the Edge HD 800 in person today...

Hi, the current 8" Edge HD appears to weigh 14 pounds? That should come in under 20 pounds with imaging gear, and if so, the mount will handle it.

Some of the older deforked 8" SCTs are very heavy and are too much payload to successfully image with, imo..

As I said, I'm currently at 21-22 lbs with the AT6RC and imaging gear, and it's excellent. The Edge 8" is not overly long either, also a plus.

Clear skies,

Paul

I saw the youtube clip you put up with that 32 pounder... wow

I'm seriously considering the ZEQ25, just a bit concerned about how it handles period error.

Hi Paul! cool stuff :-) Did you trade in your AT10RC for the 6 inch? the 10 was a beast!

No John, still have the 10", but that's reserved for the iEQ45 and TDM. I am having a ton of fun with the AT6RC though....:)

Best,

Paul

sweet! I didn't see it in your sig, but then looking again I don't see a lot of stuff you have either :-) sig space too small on CN... I knocked a bunch of stuff off to, and severely compressed what's left.

Two mounts is enough for me!
