Subject: [ap-gto] Mach 1 awesomeness!

Hello all, 

I recently purchase a second hand Mach1 from a member here who assured me was in perfect condition….well let me tell you, that was an understatement!  

I’ve been waiting patiently for a PlaneWave CDK 12.5 and on the prowl for an appropriate horse for it to ride. After speaking with George, he said the Mach1 should be up for it.  He told me precisely all the appropriate goodies I needed since it was just the mount.  Well my new chunk of American made awesomeness arrived on Thursday and I made a beeline to Cherry Springs Pa for the weekend with some friends.  In similar fashion to AP thoroughness, the PW came with every single detail attended to, including all the adapters for my specific camera. 

Well after reading the daily Mach2 torture test emails, I can attest that this 10year old mount is still a straight up rockstar!  60lbs of ‘scope and stuff’ she was a tracking machine!!   Fortunately a friend had an extra weight since apparently I didn’t have quite enough, and this was still a tiny bit ‘scope heavy’. 

Roland, George, Team AP all around….positively amazing piece of gear. I am proud to be an owner of an AP mount for sure!!  

Best,

Michael Kelly

PS, thank you Patrick Spencer!

Re: Mach1 gears

It definitely needs to be tight, BUT first call George here at AP so he can advise you on how to adjust it.

Re: Mach2 with CP five jiggling while tracking

I will send you some instructions to eliminate the oscillations.
By the way, has nothing to do with PHS2 or any other outside programs attached to the mount.

I have attached a image taken of the Veil nebula taken while the mount was jiggling in the RA axis. The length of exposure was 75 seconds and, the focal length of the telescope is 674 mm.
therefore the amount of jiggle  (length of star streak) is 2min 45sec of arc.  The telescope was visually oscillating at a frequency of about 60hz.

The only change, I think, has changed from the previous use of the imaging system may be an update of the PHD-2,6dev2 app. 

My next step is to revert the PHD-2 app to the previous version.

Re: Guider Settings

Roland Christen
 

Your setting of .01 seconds of time = 0.15 arc seconds at 1x sidereal. That's pretty small unless your star scintillation is close to zero.

Subject: [ap-gto] Guider Settings

I read in a recent discussion thread where Roland recommended that the minimum move in the guider settings should never be less than 0.3 seconds in either RA or DEC. I believe that the discussion was pertaining to the guider settings in PHD, but do the same guidelines also apply for MaxIm DL ? The screen shot below shows my current guider settings ion MaxIm DL. I have never changed any of these settings except for the delay between exposures which I changed from zero to 1 second.

What about the Maximum move ? Any guidelines there ?

Should I also have the Enable simultaneous RA and DEC corrections box checked ?

    this would explain my issue.....but is it true?

 

I have a C11 so no direct knowledge on the Meade.  Though having the locks not work sounds odd.


While it may be mirror flop, that has become something of a catchall blame point with SCT's.  Is it possible that you have something else that can move or not be orthogonal after the meridian flip?  The dovetail/rings? 


When you plate solve east and west, are you getting the same sky rotation?  Having that not be the same (or 180d off) is a sign of loss of orthogonality somewhere.   I do not think mirror flop can cause significant rotation (can it?)?

 

If you go east, then west, then back east (without recal except maybe on the first) does it return to the same place east?   I.e. is it repeatable?  While mirror flop may be somewhat repeatable, I would think it fairly random, so if it comes back to the same place consistently, I would look elsewhere first.

 

Sorry I have no real answers, but I do think it is useful to try some experiments to try to isolate whether it really is mirror movement, or something else.  I cannot tell you how many issues I have had that people kept saying mirror flop, only to find out I had some other more subtle issue in my imaging train or mounting, or mount (not my AP mount of course!).

Re: Error in APCC pro reading RA encoder on Mach2 #appc #Mach2GTO

 

Terri you can't make it come to the front in the way you are doing (believe me, i have tried)

you have to hover your mouse over that window preview and click the "X" to dismiss it

Then you can go back to APCC and click the view errors and it will come up

The hidden error window has happened to me numerous times, and I mentioned it in a previous thread.  I use the same workaround, but it’s annoying. 


difficulty removing the 8" extension used on Mach 1 mount

nicholas
 

Occasionally it takes several moments to fit the mount head on the extension as the mount angles a little up or down meaning the two cannot join flush, but with a little manipulation I can get the mount setting in the extension no problem.

Yet I was using it last night and at the end of the session, well, the temp dropped to a blistering 46 F and when I went to remove the mount head, it literally would not come apart. It made it heave then for me to have to lift the mount head and the extension all together.

Should I use some car wax or something along where the two components join? 


Re: Time change today...

You correct the issue by switching EVERYTHING over to Universal Time <U.T.> which includes your CPx control box, keypad, laptop & desktop, smartphone, tablet, etc to stay consistent with all of your electronic gizmos.
No more B.S. from going back & forth twice a year between Standard Time & Daylight "Wasting" Time.

Re: Error in APCC pro reading RA encoder on Mach2 #appc #Mach2GTO

 

Hi Terri

>>>  When I click on the button above the globe to view errors, the error log screen will not come up.  

This happens to me occasionally and I have found the error window is hidden behind other windows, but i can't get at it. 

I found if I click on APCC in the task bar, i can see all the windows, including the error window. I click the close box on the error window and then return to APCC and click on view errors. That always works for me

Hi Tom,

I tried the latest Beta and I still had the same race condition issues, but there's a good chance I just didn't
configure things. correctly.
Exactly, what configuration settings did you use? I can't correct or promote the software to a release version without logs and settings information. Just saying it didn't work is not going to help! :-)

Thanks,

Re: Time change today...

Ray Gralak
 

Hi Tom,

Was "Keep mount time synced to PC Time" enabled in APCC's Advanced settings? If so, can you post a link to your APCC log that covers the time change? APC should have changed both Time and Time Zone during a time change.

That said, there is an easy way to fix this in APCC without requiring moving the mount by hand.

BTW, you can do this in daylight:

1. Start APCC and park to Park 3 (the mount will be 15 degrees off).
2. Unpark and enable tracking.
3. On APCC's "Goto/ReCal" tab, click the "Load Mount RA/Dec" button.
4. In the RA Hours field, increment the RA by 1. For example, if RA=3, change it to 4 (if RA=23, change RA to 0).
5. Click the "ReCal" button and click "OK" in the popup window.
6. Park the mount to Park 3. The mount should now park to the correct position.

If I have the sign correct, you want to add one hour to RA when time changes from Daylight savings to Standard time. Going from Standard to Daylight Savings in the spring will require subtracting one hour from RA.

I was imaging until 3 am this morning and if course the time changed back to Eastern standard Time. I then
did a Park 3 and the mount is clearly one hour off.
So how does one correct for this?
Do I just change time in apcc and do a sync?

Re: APPM Model sanity check (suggestion)

Dale Ghent
 


Thanks, Tom! Glad you find the plugins useful.

APPM's actions at the end of a modeling run can be configured. When used from within NINA, it's suggested to set it to "No action" if your next move in the sequence is to slew to a target and begin imaging it.

That is an interesting addition to the NINA Plugin. The Ground Control plugin with PushOver support is great too. Thanks Dale!

If I have a "single target night", I might use that instead of generating a whole model. I was experimenting last night and found that I could build my 52 point model (20° increments with my wonky horizon)  easily in the time between nautical and astronomical twilight, so I may just stick with that. One thing that did take me by surprise is that it looks like APPM parks the scope when finished so I had to add another instruction to unpack the scope later on so imaging would succeed.
