I have just gone out of the house and saw that bright moon. Then I saw your statement... Yeh, let get on with more imaging. Btw that is a very nice Crescent Nebula !!

Thank you Alfred, when you have a view of Polaris, a good polar scope and a smooth mount, it makes it very easy.

I was out testing the new pole star algorithm the 14th, with an AT6RC guided with a 50mm Borg/Lodestar and this is what my PECPrep result looked like.

Cheers...Paul

Paul, (or anyone that may know),

Has it been worked out yet so that ZEQ25 works with Sky Safari?

Paul,
For us s-l-0-w learners, what is a "PECPrep from PHD Log file ZEQ25 w/CEM60 Algorith filtered"

Mostly not sure why I'm seeing reference to the words: "ZEQ25" and "CEM60" on the same line?

Thanks,
Tom

It works with mine via SkyFi.

Hi Tom, sorry. I was guiding with the ZEQ25, my CEM60EC is not functioning correctly (I did receive a replacement today).

Anyway, the iOptron software engineers developed a new pole star position algoritm which is supposed to be a bit more accurate than the position currently displayed on the HC's or the iOptron Polar Scope App.

They included the new algorithm in the latest CEM60 firmware so I just fired up the CEM60 and grabbed the pole star position readout and adjusted the ZEQ25 polar scope to those readouts.

Seemed to work pretty well, all in all. So, the mount indeed was a ZEQ25, just using the CEM pole star data.

Hope that explains it?

Clear skies...Paul

I recently put my ZEQ25 on a pier which was a great move. The mount stays on the pier while I unload the C11 and CWs. It's always perfectly level, although I have to tweak the polar alignment so far. I put a snake LED light permanently on the pier so I can use it instead of my broken reticle LED. The frost depth here is about 4.5ft so the hole was quite a project. Every night it would fill with water so to start digging again I had to pump out all the water. Finally, the hole was deeper than my shove handle..so it was good enough. Best part is I located it 6ft out my basement door. I got good shades on the windows to protect from inside lights, and voila...just a step-and-a-half out the door. Tracking and guiding has been much better. I can also get up and move around in the house without vibrations disturbing the guiding. Dan's Pier Plates did a great job with the plates, 12" bottom and 8" upper. They have the very best components and workmanship.

I just received my ZEQ25 today. I cant wait get it out there and going once these clouds roll out.

Here is a scope height comparison between it an the CG-5. It's quite dramatic.

I have the same CG-5 ASGT, and the eyepiece height is perfect with my 7" Meade Mak Cass, I use either a dining room height chair with a cushion on it or an 8" high padded stool, the former for planets low down (say 30 degrees above horizon), the latter being for Star clusters / Nebulae / Galaxies at or near the Zenith. I do not extend my tripod. Damping time is 1.5 seconds with my 7" Meade Mak in tube rings (8.5Kg total).

I would be very interested to hear how your ZEQ25 compares as regards weight carrying capacity in comparison with the CG-5 ASGT. I see that you have the standard smaller diameter tripod legs on your ZEQ25 compared to the CG-5 ASGT's standard 2" legs and in order to get the OTA to a useable height I would have to extend the legs A LOT on that thin legged tripod (your ZEQ25 tripod already has the legs extended in your picture). That does not bode well. Let us know what it's like.

I was told CG-5 can carry my C11 for visual with 2.5 second damping time? I haven't got enough counterweights to try that yet. I wonder what the damping time is on this ZEQ25 if you use the optional 2" legs tripod? BTW CG-5 EQ head is 4.98Kg without counterweight shaft, the shaft itself is 0.89kg, making 5.87kg total. Tripod is 8.5Kg so I am told (my scale only has 7kg capacity, I can't measure it, but it feels just slightly lighter than the LX90 tripod (also 2" legs but has extra tripod lower spreader that CG-5 tripod hasn't got.

Regards,

Alistair G.

Personally I rarely look though my AT6RC so I will drop it as low as possible for imaging as I use a dob for visual. I have considered mounting the ZEQ25 on the cg-5 tripod however.

I have started a thread on this forum asking for
recommendations on a light portable mount for my 8" SCT for
imaging and listed the ZEQ25 as a possibility. I have
had many adamant comments that the ZEQ25 would not have
accurate enough tracking resolution to produce good
images with my SCT yet I see your image
(posted by astronewb 9/8/13) with the 10" RC 2000mm
looks fantastic. Am I dealing with members that have
mount fever (as opposed to aperture fever) and just
can't imagine a mount under $1000 able to image
at 2000mm? I think the ZEQ25 would be perfect if I knew
I would be happy with the results.

AFAIK, Paul has only posted a very few images from his 6" RC with a focal reducer. I don't know where you came up with the 10" RC/ 2000 mm.

But I'll let Paul handle this.

Actually he did post this exquisite image from an AT10RC on the tiny ZEQ25. Almost 70lbs(35lbs equiptment) on the mount sitting on the smaller 1.5" tripod! Impressive!

I'd be more interested in consistent imaging performance. Every mount can occasionally produce stunning results when the phases of the moon and the stars align...

It would be very helpful to know if the ZEQ25 could get consistently
good images on long focal length scopes such
as my 8" SCT without using a focal reducer. If not, what
results would I get with the IEQ45 and CEM60? If I have
to use a focal reducer I will, but rather not for my small
targets.

The ZEQ would be a great choice for doing wide-field photos with a reasonable amount of weight on the mount. If what you want to mostly do is long focal length with an SCT, you might consider a rethink.

Yes, people sometimes try to oversell the larger mounts and don't seem to get not everyone wants to spend 5, 8 or 10 thousand on a top shelf mount. But if you want to load your mount down with an SCT and all the other gear, you should consider something more robust like an Atlas or CGEM that's still portable but better able to handle the weight and do so consistently.

What I need at this point is input from those that either
own or used a ZEQ25 for imaging with a long focal length
scope and what were your results and would you recommend
the ZEQ25 for long focal lengths around F10. Details
on your scope and camera would help also.

I think expectations of the ZEQ25 performing miracles at long focal length would not be adequately met. $800 only goes so far, to be frank.

Based on the other thread I'd say the CEM60 non-EC is probably a better bet.

I assume you are talking about guided imaging. If so, your results will be related to the focal length of your guide scope. There should be no reason the mount cannot produce good results with a long focal length scope, so long as you match your guiding FL appropriately. The Orion Short Tube and DSI II combo may not be quite enough to guide a 2000mm main tube.

I have an 8" Celestron Orange Tube SCT, 2000mm FL, and an ETX 90mm (1250mm FL) to guide with. I don't normally image with this scope, but if the weather cooperates I will try to get it set up with the ETX and see how the combo works on a ZEQ25. I will image at the prime focus with a Canon T2i DSLR. I guess we can see how the results look and then decide the question.

Cheers,
Charles
