Sounds mechanical, not electronic. We can check out the RA axis, but you would need to talk directly with Howard or George about your situation, and they may want you to do some simple tests. Rolando

Mike, Is there an OPTEC log which might indicate very minor rotatorcompensation, (due to the STL series cameras (chin) balance offset), trying tostay on-angle? Do some runs with rotator powered

Have an issue with RA tracking/guiding. -1600GTO, have greased RA and DEC, set gear mesh, trained innumerablePEC curves. CP4 electronics, there have been no software upgrades to theCP4. The

I had thought about something like this, but Howard seems to have negated it. However, but my OTA alone weights over thirty pounds, so would likely tax any such device... Chris

Howard, thanks! I will do this. Chris

I have received Woody's defective power supply and will checkit out tomorrow. -Christopher Erickson Observatoryengineer Summit Kinetics Waikoloa, HI 96738 www.summitkinetics.com

I would not in your case. Rolando

You would can use the "Refine" tab, but I wouldn't with a Pk-Pk of 0.3 arc-secs. The PEC scheme in the CP3 and CP4 is excellent so you should be able to get below 1.0 Pk-Pk without a refinement. -Ray

How do I add the second curve to the first? joel

You can do that, but DON'T download it into your mount. It will wipe out the gain that you made with the first one. The second curve needs to be added to the first, and the sum is then downloaded. If

AH, never mind. I'm an idiot. I measured the corrected PE with PEM on and after 6 cycles the corrected PE is only 0.3 arcs peak to peak. So I will leave it at that. joel

I have measured the raw PE of my Mach1GTO, and with PEC off the PE is 5.3 peak to peak. After recording 6 worm cycles and uploading the PEC curve the new PE is 1.2 peak to peak. My question is

Thanks Woody. I have the ADM but it’s for the “D” size. The ADM “V” model has a Vixen slope, which I do not want.

Dave, TheBaader device is called the "Stronghold Tangent" and costs around $400.00. Baader says the capacity is 7 kg (15 lbs.). As I recall, I looked at thisone but didn't think it was as stiff as

Woody, Would you happen to have the links to the ASA and Baader alt az units? I can't find them anywhere. Thanks Dave

Hi Guys, Woody's suggestion is a good one as long as you remember a few things: 1. You may still have some differential flexure between the two scopes, even after aligning the heavy-duty adjustable

Chris, Something else you might consider is a heavy-duty guider mount for the130. I'm thinking of something like an ADM MaxGuide or Baader's similardevice. I think ASA makes one too. There are

I just installed two OTA's on my 1100AE mount. An FSQ 106 I use for imaging (my PRIMARY scope; the one tuned to APCC, et al.) and a TOA-103 I will use for visual. Accepting that when the FSQ is

Oh, that's amazing! Thanks!!!

Initial altitude angle does not change the procedure or the accuracy. Rolando
