Re: Problems conducting pier flip with G-11 #G11

JI THERIOT <ji.theriot@...>
 

Jerry,
My issue was a combination of three things:

1. Andromeda being in just the right position when overhead to have my camera in-line with the pier

2. My OAG and guide camera reducing the clearance between my scope and the pier

3. The location I chose to mount my USB hub was less than optimal

Interestingly enough, with all of the imaging I’ve done, I have just never run into this issue...just the luck of the draw with the target I chose this time.  Anyways, moving the USB hub helped to clear things up.

Hi Ji,

Thanks for the update on your problem. Wes and I had a few minute conversation about you problem, and we came to the conclusion that the most likely scenario was that your telescope was contacting your tripod and causing it to stop. That prompted us to have conversation about mount limits and how we might create a program to model "keep out zones" that could be used by the ASCOM driver. We need to have more discussions on this, but if anyone has any thoughts on this, I will start a new thread to have that discussion.

Clear Skies!

Right.  Great work.

I want to.point out to the group that if the mount performs a slew and is stopped by a mechanical interference the motors will not stop.  The PMC8 just keeps driving them until the correct motor steps are reached.  The motors however are unable to move the mount due to the interference, thus the PMC has an incorrect idea of the mount location.  Any subsequent mount movement will go to the wrong place. Your analysis, assuming the leg strike, is spot on.

Re: Problems conducting pier flip with G-11 #G11

JI THERIOT <ji.theriot@...>
 

Jennifer,
No worries. These threads are started to try to solve issues, hopefully yours get figured out as well.


All,
I wanted to update everyone on my issue.  Unfortunately, Thursday night clouds rolled in before my scheduled meridian flip. Last night however was perfect and I was able to run my entire program and stay up to watch it.  On Thursday night I had identified a possible contact point between my OAG guide camera and where my USB bus was attached to the mount.  I moved the bus to the leg of the mount while I was setting up last night. I also increased the plate solve search regions in SGP to “Max Regions”.

Anyways, the program ran though last night with no issues.  I think I am pretty certain now that there was some contact between the OAG and some part of the mount which  was causing a loss of steps...enough that the mount was not getting close enough to the target to be located during the plate solve process.  Thanks for the help in trying to resolve this issue.


Ji

I apologize for hijacking your thread. I hope you can forgive me.

Wes

I received your message and I think my response to Jerry below addresses your questions.

Jerry

I did not have clear skies last night in VA, but I was able to check the FW version which is 9T13 and conduct some indoor testing.  

I started all of my programs like I would when I am outside in the following order:  POTH -> ASCOMPAD -> PHD2 -> Stellarium Scope -> Stellarium -> APT (camera 1) -> APT (camera 2).  Confirmed everything was connected and playing nice.  Then I slewed to NGC 7293 aka C63.  I then Synced the coordinates with Stellarium.   I waited until NGC 7293 passed over the meridian.  Next I used APT’s Pointcraft via Blind Solve with ASPS to solve an existing image of NGC 7293.  I parked the telescope and it correctly went to home position. Then I slewed back to NGC 7293 and the telescope correctly went to the other side of the pier.  In this indoor scenario everything worked as it should.

The only difference between the indoor and outdoor scenarios is APT’s Session Craft is used when outdoors.  Session Craft is APT’s built in Meridian Flip tool that monitors the telescope’s position relative to the meridian.  The tool can be set up to automatically complete a meridian flip based on the following parameters:  user inputs # of mins ( default is 5) before the object reaches the meridian and user inputs # of mins (default is 5) after object crosses meridian.  If the user enables Session Craft’s auto meridian Flip the following occurs using default values:  5 mins prior to reaching the meridian APT automatically takes a 15 second exposure and plate solves to obtain the coordinates -> APT stops PHD2 and mount tracking -> 5 mins after crossing the meridian APT flips the mount, enables PHD2 and tracking, waits for the mount to settle, and takes a 15 second exposure -> APT’s Point Craft blind solves the image, automatically syncs with Stellarium, and slews the mount up to 5 times to to recenter and reframe the object.  

Could the mount behavior I am experiencing be caused by APT disabling the mount tracking?  I did not have this issue before and have not changed the APT release version (v3.71) nor the ES PMC-8 ASCOM driver (vAnyCPU).  I double and triple checked my location settings in ES PMC-8 driver, Stellarium, and APT which syncs to the ASCOM mount driver.

The only other possibility is that Windows recently installed updates and I have read that Windows can wreak havoc on ASCOM drivers as a whole.  

Unfortunately I will not have any definitive results until I can get everything outside again.  Here’s hoping for clear skies.

Apt plate solving works like a charm.  Everything u need in integrated into apt.  It will also use PhD server mode to guide or you can just guide outside of apt with PhD.

It's a great app.

Nope, the D5300 is stock.  When I did my Veil exercise / CLS-CCD first light, I got lots of advice on CN about getting modded.  I wouldn't mind, but it ain't so simple (or inexpensive) on this side of the 49th and in CAD$. And then there's my unexpectedly-fussy-about-spacing FF that I don't want to mess up.  I looked at cost and risk, and I'm pretty much ok with leaving well enough alone for this camera.  I'm actually pretty surprised at how well it's doing with Ha.  I know that it's costing me time, but so far this looks manageable.

Hi Steve,

Thanks for the link, I read that article before I downloaded the app and I think I set all the settings according to my current imaging setup. I'll have to work on APT and Astrotortilla to figure which one works best for me.
Another journey..

Hi Max -

If Astrotortilla is still an option for you, check out this tutorial...it will help you to understand what the parameters are so you can make informed choices for your setup.

Alright, so I downloaded Astrotortilla and also additional files to match the Celestron C5 field of view.
The app connected to the POTH Hub no problem.
I set the scope in the default position and unparked it, slewed to Vega and of course missed it.
Then I switched to Astrotortilla and hit Capture and Solve. It captured image in APT but then nothing happened.
It just displayed No solution in 0.0s. And the current and target coordinates almost match.
I've tried multiple times to slew to different stars and it kept showing the same message.

I am now asking for help as I have no clue what's going on here. I would appreciate any suggestions.

Thanks,

Hi Jennifer,

I am curious about this as you can imagine. The problem I identified was in the ASCOM driver after the first release back in 2016. This was related to doing a pier flip after tracking past the meridian and slewing back to the target on the other side of the meridian. It would not calculate the correct side-of-pier to slew to and therefore tended to point to the ground. I corrected that issue early on. I don't believe I introduced any type of error of this sort in the firmware, but you never know. I will re-examine the changes I made in the firmware between 9T11/12 G11 and 9T13/14 G11. I will also test this out today in our observatory to make sure that with the latest G11 firmware that when tracking past the meridian that you can slew back to the target and it will do a pier flip correctly.

As far as PARK is concerned. All the ASCOM driver does when it sees the PARK command is drive the motors to home or 0x000000 (zero) motor counts on RA and DEC. This should be where you were at when the PMC-Eight was first powered up as long as you did not release the clutches and manually move the mount. As long as the PMC-Eight is powered up it keeps track of the position. As I have said previously. The only thing that would cause the PARK position to be wrong is that if the PMC-Eight microprocessor was rebooted at some point with the mount not in the PARK position, it would then think that the mount was PARKED after reboot.  The POTH allows you to also set a PARK position that is not HOME, so if those are set, it would drive the mount to those motor counts as the PARK position. Only HOME is defined to be the NCP with motor counts on RA and DEC set to 0x000000 (zero)

Thanks

Re: Problems conducting pier flip with G-11 #G11

I am also experiencing some weird and wacky behavior from my PMC-8 when attempting a meridian flip.  It seems like the mount becomes senile and when I park the mount after a meridian flip it thinks the park position is on the east side of the mount and tries to position the telescope towards the ground.  It has done this the last 3-4 times I have been out.  I seem to remember Jerry stating this issue was identified and remedied with a FW update.  I thought I had the latest FW, but I will double check tonight.  Hopefully that is what is going on in my case.  In any event I will provide an update.

Hi Patrick,
I am not sure what you mean by having to cannibalize some parts from the different tripod. Currently, to use the azimuth adapter, you would need to buy an ST2 tripod (now known as the Twilight Medium Duty Tripod) to go along with it. You would not be swapping parts with your ST1 tripod at all, that would remain intact. So your choices once you purchase the ST2 and the azimuth adapter are to use the ST1 without precise azimuth or use the ST2 with precise azimuth. We are working on a solution for those who want to use the azimuth adjuster with their current ST1 tripod that is why I asked the question in the poll as to how much more you would be willing to spend if you could buy the azimuth adjuster, currently $99.99, with the extra parts to make it work with all of the tripods, ST1, ST2 (Twilight Medium Duty Tripod) , or ST3 (Twilight Heavy Duty Tripod).

Thanks
