Re: Smart Meridian Flip with NINA #APCC

Joseph, I'm catching up on emails after a vacation. Is this still an issue? If so, can you share your .mlm file?

The smart meridian flip didn't work well for me last night. I ran a 28 point APPM arc before imaging. When I started the sequencer the telescope slewed directly to the target, centered (no movement was required as it was centered already) and focused. Before NINA started imaging the meridian flip flow alert popped up indicating a meridian flip was scheduled in 35 minutes - which was wrong based on my position. The program didn't start imaging but just seemed to be waiting for the flip. I canceled the alert and NINA started imaging and the interval east of the meridian was uneventful. The flip came at the correct time indicated by the sequencer, not the 35 minutes initially indicated, but after the mount flipped it ended up pointing somewhere north of the target - plate solved - then slewed further away from the target. I attempted to repoint the mount using CdC and it also went the wrong direction. Shortly after APCC crashed and after restarting the virtual ports I use 20 and 21 had been replaced by 8 and 9. Tried reslewing to the target and it was clear the mount was lost. Manually moved it to PARK 3 and closed it up for the night.

The standard meridian flip worked great several days earlier. The smart meridian flip not so much.

I can provide logs if anyone is interested. I'll check in with the NINA forum as well.

During simulation is the mount actually pointing to the object? How would you know if it was done indoors during the day?

No,  you should not need to, the RA/DEC should be provided by the connection to your mount and/or by the FITS headers (not completely sure which, they both provide it).
 
If you were doing this running the simulator you should also connect to the same simulator in APPM and NINA.  Both NINA and APPM should have a connection to the (same) mount.

Re: APCC - APPM - and ASTAP

Jack Huerkamp
 

I received this from Han, the author of ASTAP after sending him one of my PNG images and the astrometry.net solve of it:

Hello Jack,

It solves see attached screenshot settings.

Enter an estimate position ( ra=1.5, dec 30)  in the viewer or double click on RA and enter M33.

field of view (height) is 0.42 degrees or put this on auto

Use H18 star database since your field of view is small.

un-check calibration.

Note you can go fully blind by entering the search range of 180 degrees. You could also set FOV on auto but that takes time so better enter 0.42degrees for your system.

Clear skies, Han"

I tested ATPAS with several images this morning and it did solve them if I put in a rough RA and Dec position.  I assume that will not be an issue while running APPM as the mount's position will be indicated in APCC and I could feed the position into ASTAP for the purpose of plate solving.

I hope my logic is accurate as I hope to try an APPM run as soon as the skies clear.

Yours truly,

Jack Huerkamp

Re: RA Mesh adjustment for 2104 model Mach 1 GTO

Roland Christen
 

Hello Nicholas,

I think in your case the first order of business to get your mount up to snuff is to take a 15 to 20 minute run in PHD2 and get a screen shot of the guider graph. Use 2 second exposures on the guide star. You want to turn off the guide corrections and just let the mount track and record the tracking graph for RA and Dec. Make sure that you have turned off PEM for this initial test because we want to see what your mount baseline tracking is. The Dec portion of the graph will let use determine what portion of the tracking noise is atmospheric (seeing) induced.

One very easy way to do this is to use the Guiding Assistant in PHD2. Set it to run for at least 15 to 20 minutes so that you capture 2 to 3 worm cycles. You want to point your scope to roughly 0 Declination near the meridian (either side is fine). Once you get this unguided tracking graph, I can determine the health of the RA axis and the basic mount and maybe suggest some things you might try to make the mount perform better.

For the Dec axis, the best way to determine the health of that axis would be to run the backlash test and post the graph. For now, do not make any adjustments to the mount until we can see these baseline data points.

Can you do these test for me so I can help you get the most out of your new-to-you mount?

I would like to know from other owners of AP mounts if you are fully loaded and you grip the counter shaft and use a small amount though distinctive force through the DEC axis will you  notice any discernable movement of the RA structure? I do, when it is fully loaded. It is a small a amount, maybe 1/8 MM or less. but that movement is discernable. 
 

Thank you!

Re: Mach 2 Meshing

Roland Christen
 

The worm assembly is on a pivot and uses springs to gently push it into mesh. The backstop is set to allow only a few thou of in-out movement which is enough to keep the worm always in mesh. The worm wheel is precision machined with extremely low eccentricity.

A proper bracket would be nice.

 

First, I agree, and love Joel’s work.

 

I did a bit of research and want to correct an impression prior photos may have left if we are talking about going under the saddle. Be aware of the dimensions.  Mine was a PPBadv, which the web site specs at 25mm; the ultimate is 30mm. 


I also realized the photo I sent earlier was incorrect – the gears were disengaged, which left the motor housing lower.  This is the spacing with the mesh engaged at closest approach:

 

 

That’s probably less than a millimeter, and I realized I actually risked a crunch there without realizing it, though it does clear.  But if you go beneath, the natural approach is swinging it with the mesh disengaged – be aware of the height difference.  Or disengage the clutches instead to check clearance.

 

Above (i.e. bottom of the PPBadv) there is more clearance, about 3mm (eyeball estimate) where the bracket holds it off.  This is not adjustable with the holes in it now. A bracket with no hold-off could save that space, but on the 1100 if the 30 vs 25mm height is right, there is NOT clearance for the Ultimate in this location even flush on the saddle.  On the front yes, since the DEC motor housing and saddle clearance do not change with rotation (well, unless you rotate DEC anywhere near 180 degrees of course then it may hit the RA housing).

 

Anyway, if you are looking at the saddle, do swing both axes in all the positions you  plan to use as there is not much room under.  Just barely enough for what I did.  And if someone makes a bracket to go above or below the unit, even the PPBadv is not going to fit on the back side.  Well, unless you stick it way in the back beyond the motor housing on the tip of the saddle.

Fwiw Pegasus does sell a way overpriced bracket at least for the UPBV2 which fits no hole pattern I have on my plates.   I was suspicious and should have stayed away from that unnecessary expense… definitely not a get-what-you-pay-for situation.  It is possible Pegasus supplies brackets for the other models perhaps with better fit to typical plates. 

As for a “proper bracket”… The buckeystargazer mounting plate is an exact perfect fit (am using the UPBV2 here) with optional choice of dovetail mounting.

I liked it so much, I bought another for my SI-EFS control box.    

Maybe you are looking for some sort of machined aluminum bracket.   Fwiw such a bracket is likely going to add some weight to the OTA (whether top of bottom mounted).  I have a couple losmandy “dovetail adapters” that I used for mounting things like the old dewbuster on top of the OTA  … The DA was very heavy and clunky.  

The lightweight plastic seems to be more than robust enough , and it fits the dovetail without the usual aluminum-on-aluminum grinding.   Best of all it is very lightweight adding almost zero weight… certainly nothing noticeable like the old DAs. 



Keypad : some buttons not responding too well

michael mccann
 

Hi
Let me know if there are things that I can do to better resolve this, troubleshooting or answering questions. Let me describe
The “Next”, “5”, “0” buttons are “slow” or don’t respond unless I press several times. So far these buttons seem problem childs.
Is this normal wear and tear sort of issue? Is there a replacement keypad part that I can purchase and install ? Does AP repair this sort of thing? I bought the mount and keypad used so I’m seeing how the previous owner used it.

Cheers

Mike

Thanks for the help  Sebastien!  
Of course!
 I see your gear came with a matching dog!!  Outstanding!!
Yep, and as the mount it can be operated down to extremely low temperature ! Moreover, it is a perfect cold feet heater too! Just very bad for the PA when he mixes yours with the tripod's ! 😆
