Mach1GTO - Crazy calibration with PHD2

Samara Nagle
 

Hello everyone, this is my first post here. I am the new owner of a Mach1GTO puchased last Christmas. Love my mount but don't get to use it often because of the horrible weather here in Ohio. Last night I woke up very early and it was clear so I decided to just play a little bit, ended up with another problem to troubleshoot. PHD's calibration was all over the place, which is something that never happened to me with any mount. The mount is permanently set in it's pier in my observatory in the backyard and since I bought it I never moved it. There are no cables snagging because I have a Rigrunner and USB hub sitting on top of the OTA and only 2 cables coming out of the mount, power and USB and those are very well anchored. The scope is a Celestron Edge 11" and the mirrors are locked because I use a Moonlite Crayford focuser. Anyway, I am a little lost here and the only thing I noticed different is that there's now a little bit of RA play. Any suggestions? I'll try to add the screenshot of the problem to the Photos area. Thank you!


Re: Specifying the Optical Reference Point on any Focal Reducer ?

Joe Zeglinski
 

Hi again,
 
    Please ignore  my initially posted thread. Upon re-reading, I found my answer  at the AP webpage, in AP’s very well written and detailed document on using their “Telecompressors” (focal reducers).

    “Astro-Physics Telecompressors - 27TVPH & CCDT67 Compression and Coverage”

    Some of my confusion came from reading tech specs on a competitor’s website – like Celestron’s  reducers for the HD-1100 and HD-1400, where they provide back spacing but NOT the FR Optic’s focal length. There was also further confusion in initial info whether that was measured from the base of the output threads (i.e. right from the final lens in the group, inside the threaded flange), or from the rear “flange” (which is the correct reference point). The HD Reducer’s body length is unpublished as well.
 
   Even though the required SPACER Length is indeed provided, without knowing the back focus taken up by their HD accessory, one can’t determine its impact on an OTA’s known available back focus distance.HD FR is assumed to be directly attached to the back of their HD OTA.
    So, with two unknown factors,  “optic focal length and accessory overall length”,  there would insufficient detail to use Rolando’s “formula”.

   “FR COMPRESSION = ( Optic Focal Length – Distance from FR Optic Center to “Primary” Focal Plane ) / Optic Focal Length”

All this is fine if the FR is used only with their HD scope, but not enough detail if this optic is purchased for use on other brand scopes.
 
    Doesn’t seem to be an industry standard for stating all the detailed specs, perhaps an oversight at Celestron, and others.
 
Thanks for your patience.
Joe

Hello,

 

With APCC/Horizons I use my AP-1200GTO CP3 to track on comets and this works well, this was the main reason to buy APCC (standard version) about a year ago.  But it also worked well on NEO 2014 JO25 that passed by the Earth on 19 April 2017 with a relative speed of about 2.5°/hr, see http://astrob.in/292386/0/.  Up to know this the fastest object I had the system guide on via APCC.  These are ten 60s exposures tracked on the asteroid and then combined, there was a pause of about 120s between images 2 and 3 should any one wonder why there is a spacing in the track of the stars.

Specifying the Optical Reference Point on any Focal Reducer ?

Joe Zeglinski
 

Hi,
 
A question on Optics ...
 
    Does anyone know, for certain,  if there is any “optics industry standard” which defines the exact point on a focal reducer lens barrel,  to measure the length to the required spacer , in order to get the published “reduction factor”?
 
     I have assumed that as with all lenses, the distances are always measure from the vertical axis of the CENTER of the LENS, rather than from the back end flange of the lens cell itself. Since Barlows and focal reducers are often a compound lens, it makes it somewhat difficult to be sure that the  ...  “Unmarked” optical reference point ...  might be at the “mid-point” of say the 27TVPH lens barrel, rather than the “Scope side’s, flange edge”. In fact, a compound lens may not necessarily be positioned exactly at mid-barrel, so the “effective” optical center for the reducer spacing may be imprecise.
 
    It might be that it would take a bit more effort to “stamp” the optical centre point, so FR makers simplify by quoting the shortened, offset,  (slightly reduced length) of required spacer size, by referring  to the END to the lens barrel. As these are seldom offered together as a set, the precise measurement is lost in actual use.
 
    Perhaps, one such example, excerpted below, of the confusing results for lens measurements,  was in Russel Croman’s widely published and much read paper, where he seemed to have some difficulty in ascertaining the “correct starting position” to measure the required spacer to get an EXACT  0.75x focal reduction – using the AP’ 27TVPH lens in his test.
 
*******************************************************
Proper Positioning of a Focal Reducer
on a Ritchey-Chrétien Cassegrain Telescope  ... (Copyright 2002) by Russell Croman

   “ Note: the AP web page for the 0.75x reducer states that the distance from the edge of the 2” adapter should be about 65mm for 0.75x reduction. However, measurement of the reducer and 2” adapter combination yields a distance of about 60mm from the back of the optics to the back edge of the 2” adapter. Thus, according to the above computation, an additional 115mm is needed to achieve 0.75x. Using a 65mm spacing from the adapter to the focal plane will yield approximately 0.82x reduction.”

**************************************

    So, my question to experts in the group ... At which reference position on an FR  lens cell barrel does one start to measure the required “Spacer separation”?  

And ... is this reference position – (front, back, or center) -  common to  all brands of Focal Reducers & Barlows?

Thanks for any advice, as I am in the same quandary in my present project – and guessing it might be at the geometric center of the lens barrel.

Re: APCC/ASCOM driver report

Ray Gralak
 

Yves,

As I think I wrote earlier, the auto-config has nothing to do with this issue. The only reason that the driver would switch sign is the driver thought that there was a pierside change. To confirm that, I think I asked you for logs, which I have not seen. :-)

Again, please let's take this offline and be sure to send the logs to both A-P and me. I'll explain in more detail about the pier side change in a private email to you.

Another thing, the ASCOM driver Custom RA Rate value display is completely
different from ACP orbital tracking and from APCC (when not using tracking
correction).
I think that the rate values displayed by the ASCOM driver and ACP rate are simply in different units.

Hi Ray,

Last night, I've set "ON" the "Calibrate move direction on first slew (recommended)"
in the ASCOM driver but noticed it was disabled during the night. I've found the
disabling took effect only when APCC-AP V2 Driver Auto-Config is checked.
Otherwise the ASCOM parameter didn't change.

Backlash in our latest spring loaded gearbox is vanishingly small. It is not an issue in RA for guiding in any case. As far as Go-To, the mount will move to within an arc sec or 2 of where you command it in both axes.

The posts about guiding and backlash got me thinking about the apcc/ap v2 settings for backlash in the new mounts. quick question.

Do the newer mounts not use software to compensate for backlash? Is there no backlashin the newer mounts or do you physically remove backlash via the gearbox? Or is the backlash removed via the spring loaded gearbox? Maybe something else?

Thanks.

Sounds like you may have a backlash issue in you RA axis gear train. Another possibility is the set screw on the gear attached to the worm gear shaft could be loose.

Back story...I gave up on imaging a year ago because of a guiding issue that suddenly appeared and I could not remedy.

I now have a new computer, and new connections between that computer and the serial connections (ie new USB-Serial)  Mount is a 900.  Never gave me problems before.  Tracking and gotos are not effected at all.  Problem is when I hit "Guide"

Normal setup is using AP driver (current version) with ACP, Maxim (6.11 have seen behaviour though in other versions) and FMx v4 all connecting to the mount through the A P driver.  Guider is an Orion Starshoot (KWIK Guider).  Setup is in a dome.

Calibration of Guider seems to be issue I think.  The "L" pattern forms, but then there are some calibration runs when the final return jog shows zero movement.  Other times I do get a full proper "L"

When I do get the proper pattern and then start guiding, I watch as the Guide star gets sent all over the place and then out of the window.  Lowering the Aggressiveness simply extends how long before the star is lost, but does not help that it wanders all over the place.

To remove Maxim from the equation, I have tried guiding with PHD and see the same behaviour.  PHD seems to be happy with its calibration run, but then goes nuts as soon as it attempts to guide.

Please....help me track down the source of this issue...I really want to image again!

Re: Guiding Issues

Roland Christen
 

Usually when the guide star moves out of the box it is because the pier flip box in Maxim has been checked. What this does is to reverse the calibration moves so that instead of the guide star slowly moving toward the center, it starts heading away from the center and eventually moves out of the guide box.

When you do your calibration, do not check the pier flip box.

All is fine!



I got the computer back in the observatory, powered on the AP1600 and started
APCC without incident.



I then started TheSkyX, connected to the mount and had it go to the Sun.



I then started SkyTools 3 PRO, configured the telescope in it to "TheSky Controlled
Telescope" as Antoine Pavlin had mentioned, and connected SkyTools to the
mount. The Sun was centered in the SkyTools interactive atlas.



I then clicked on some targets on the SkyTools chart, did a slew and all was fine.
The target selected was now under the cross hairs in TheSkyX.



All is fine?



Thanks to all who responded to my initial inquiry about using SkyTools and he SKy

Yes, I guess I should have made that more clear. TheSkyX has
programming
interfaces which can be used by other applications. It works similarly to
ASCOM
interfaces. SkyTools would have to be specifically programmed to use
TheSkyX's
programming interface, if it hasn't been already.

Once connected with either, I can move the mount to a target by clicking

Hi Jack,

APCC is "downstream" fr om TheSkyX/TPoint, so to use TPoint in
TheSkyX, I think
you would have to connect SkyTools through TheSkyX, using TheSkyX's

targets. I much prefer SkyTools charts to those in The SkyX since I have
been a
BETA tester and user of SkyTools since its original release. But I have
been using
T-Point with The SkyX to improve the accuracy in acquiring targets. Is it
possible
to
connect both The SkyX and SkyTools 3 PRO to APCC and use the T-
Point model
while using SkyTools 3 PRO to select and go to targets?

Re: backlash, apcc, ap v2, gtocp4, new gear mesh mounts

Ray Gralak
 

Dave,

The driver and apcc don’t have backlash controls for the cp4 because the backlash correction commands were removed from the cp4. I think the reason was that people would sometimes set the backlash value incorrectly and that was causing guiding problems. A-P has been recommending a 0 backlash setting for some time, so this essentially enforces that recommendation with the CP4.

I ask because of the appc and ap v2 driver setting to remove backlash (gto cp3
only). Why not with the gto cp4? You can use a cp4 with older mounts as well so it
can't be the new gear box.

I see now on the ap website that the backlash setting was for manual guiding back
in the day:

"Does not have R.A. and Declination backlash control. This was initially designed
for manual guiding."

Thanks

Re: APCC, The SkyX and SkyTools 3 PRO

Jack Huerkamp
 

Ray,

 

All is fine!

 

I got the computer back in the observatory, powered on the AP1600 and started APCC without incident.

 

I then started TheSkyX, connected to the mount and had it go to the Sun.

 

I then started SkyTools 3 PRO, configured the telescope in it to "TheSky Controlled Telescope" as Antoine Pavlin had mentioned, and connected SkyTools to the mount.  The Sun was centered in the SkyTools interactive atlas.

 

I then clicked on some targets on the SkyTools chart, did a slew and all was fine.  The target selected was now under the cross hairs in TheSkyX.

 

All is fine?

 

Thanks to all who responded to my initial inquiry about using SkyTools and he SKy together.

 

Yours truly,

 

Jack

Hi Jack,

Ok, let me know if you still see an issue once you have your computer back in service.

Re: PEC Results

To add to Ray's note.

What made everything click was using CCDSOFT V5 for the PEMPro calibration Wizard.  

My guide camera is an SBG ST-i. I had forgotten that CCDSOFT V5 came with the ST-i and was trying other software/camera combos.  Once I used CCDSOFT and the ST-i with PEMPRo V2, the calibration and PR correction worked like a charm. .

If you could post your guide logs on the Stark Labs forum. The proper people will be able to analyze what the problem is but, I would post logs using the regular guiding and the pulse guiding.

I believe the instructions for posting the logs are listed on the Stark Labs forum and in the instructions for PHD2.

You can find the instructions here: PHD2 Log File Instructions.
