A three star alignment would be welcomed. Having a Celestron Edge1100 on my CGEM DX then my CGE Pro, I had no problem achieving 95% or better goto with the target near the middle of a 200x 82 degree eyepiece. For a visual setup on a non-imaging night, a 3 point model is much more acceptable than a 20 point model.

Hi Ray.

Just wondering if you have an idea of why the pier keeps flipping when I try to make a pointing model with additional points beyond the meridian.

Thanks

A general question related to my previous request for an APCC user entered field for cone error correction. Just asked out of interest ......

 

Is there a reason that AP handsets and drivers/APCC do not support 3-star alignment? I appreciate that cone error (and PA misalignment) are non-mount issues, but on other (lesser!) mounts whose software supports such multi-star alignment the model from a quick 2 or 3-star alignment goes a long way towards making gotos relatively accurate.

 

I use my Mach1 for imaging and so use plate solving. But if I was doing visual, I wouldn't want to be forced to correct cone error with every scope I put on it. I'd just rather do a quick polar alignment and then a 3-star alignment. After that, especially with the accuracy of an AP mount, subsequent gotos would be very good I'd imagine.

Re: Mismatch SGP and AP mount DEC & RA

George
 

Carlos,

 

Please reference the Quick Start Guide to be sure that you have your settings correct and that you are connecting SGP through the AP V2 driver.   See:

https://astro-physics.info/tech_support/mounts/quick-start-workflow-guide.pdf

 

Let me know if that takes care of the problem.

Subject: [ap-gto] Mismatch SGP and AP mount DEC & RA

 

 

Hi Group

Looking for some guidance. Any help would be appreciated.

  1. I only run the scope/mount through the SGP using a AP 1100gto with APCC ASCOM.
  2. The mount is point towards polarize with Az 00 00 deg, Alt 36 32 and RA 18:34 and DEC 89 59.

In APCC and APV2 all the co-ordinations agrees but in SGP current RA is at 23 51hrs and DEC at 89 53 deg.

 

I do have polar alignment completed with the RAPAS and PEMPro then calibrated to a star using RCAL. 

 

Question 

1. SGP uses J2000 could the difference is due that APV2/ APCC uses JNow??

2. I have doe the PA and calibrate with RCAL, have i completed the calibration or I am missing something??

 

How can I do something else to ensure that the issue is not related to AP and not SGP,  for example using PEMPro PEC

Re: APCC feature request

Paul
 

But entering one field manually would be enough for what I want.without any extra work at all :-)

And for the visual scenario I raised, a simple 3 star alignment as per other mounts would eliminate the majority of the goto error (and PA error if there was one of note). If using the hand controller, the APCC Pro model wouldn't even be an option either, I guess.


Re: APCC feature request

Ray Gralak
 

But if I have to do extra work e.g. doing alignment points,
I wouldn't bother and just stick with the goto being 16-20 mins or so out
when I meridian flip and letting the plate solving fix it up.
You should be able to complete 20 points easily just after dusk before the sky is completely dark.

Sticking to my query re adding a quick APCC field for rough cone error correction by the user - in my case I know
my cone error is around 8-10 arcminutes. I could shim it (and will probably try that), but it'd be easier to have APCC
correct it for me. But if I have to do extra work e.g. doing alignment points, I wouldn't bother and just stick with the
goto being 16-20 mins or so out when I meridian flip and letting the plate solving fix it up.

Re: APCC feature request

Paul
 

Sorry I've got two questions in parallel. One a request to add a cone error correction manually (for a bit extra goto accuracy with imaging rig as a quick and dirty cone error fix) and the other re why a 3 star alignment is not supported (for visual - just hypothetical for me as I don't do visual with this mount). Not sure to which you're referring. Sorry. My bad for conflating what should be two threads!

But doing even a 10 point model is too complex and messy in comparison to either.


Re: APCC feature request

Ray Gralak
 

I image with plate solving and so don't need it
Why not just do a small pointing model with 10 points on each side? That shouldn’t take very long.

Thanks. Yeah, as I said. I image with plate solving and so don't need it (though I'd appreciate that cone error setting
I suggested just for flexibility and convenience). But I was just curious and pondering re 3 star alignment and visual
work and why it wasn't supported by AP, as without it the AP mounts are lacking as compared with the convenience
of other mounts.

Re my specific OTA, yes, most of the cone error can be eliminated with a bit of effort. But it shouldn't be a necessity
to do this. And for anybody setting up from scratch for each session it may be that their cone error setting won't hold
up between session. It can be hard to eliminate it completely in any case, and it just seems common sense to let the
software take care of what's left.

Re: APCC feature request

Christopher Erickson
 

I don't know what type of OTA you have but even the floppiest of OTA's can be carefully collimated and orthogonally squared up pretty well. And unless something significant happens to the OTA, the ortho won't need to be done again.

Mirror flip and/or focuser sag might create some residual dynamic ortho error that can't ever be dialed out completely but almost any OTA can be improved significantly.

I hope this helps.

And FWIW, I suspect that AP will eventually add software ortho compensation to their hand controller(s) for situations exactly like yours.

But I guess my question is in there any reason why it's not offered as an option in the software? It's not hard to add.
