Re: Platesolving not as accurate
?
Oh right, duh!? I used to know that when I used PC apps under ASCOM.? With ASIAIR's planned community ecosystem I have basically forgotten all of the issues that need to be looked at every time you change or add something to the system.??
?
I think this is a major positive to having a single brand system in this regard.? All the internal arguments are settled within that single app.? Even so it still seems that people have had and continue to have issues with the ASIAIR controller with certain brands of mounts, even the ZWO strain wave gearbox mounts.? It's a wonder that a 33+ year old mount with a 25 year old GOTO controller works at all let alone nearly perfectly with the ASIAIR and ASIAIR app.??
?
Honestly I'm not missing chasing down this kind of minutiae to get my imaging gear to work.? Granted putting up with that is part of the hobby, for some part of the fun of getting to pick and choose your hardware but I really can't complain about the ZWO hardware other than the color and the fact that everyone else is using the same gear.??

Re: G11 tracking and parking problem
Wow! Why have I not read this or seen it it any videos. I have been through all Losmandy?docs and videos that I know of. Maybe I ignored it but I don¡¯t think so.

That is actually how it's supposed to work with NINA. The ASCOM driver tells NINA what precession coordinates are expected by Gemini, and NINA tries to ensure that the correct coordinates are sent. This may not work if some of the other apps settings are changed after they are connected to NINA, or if the apps are not reporting their precession settings correctly for some reason. It's a complex problem with many moving parts, all coordinated (pun not intended!) by NINA.?

Since it shows the selector for the encoder resolution, it's "new enough" :)? I'd recommend to run the ASCOM driver while connected to Gemini, and then bring up the advanced settings window. This will generate a with all the information sent to and from Gemini. From this log, I'll be able to see what Gemini returns for the firmware/PIC version check.

Re: DEC: Heavy Duty TR alarm - G11
Hi Bren, that's a mystery! The screen shot that Trevor posted indicates that the encoders are still at 1x resolution, which the L6 firmware automatically sets to 4x when it first detects v3 PIC firmware.

Hi Trevor, the screen I wanted to see was with the Firmware version on it (Firmware/SRAM screen). But what I'm seeing from your screenshot, either the main unit firmware is not updated to 6.x or the servo PIC controller is not updated to v3.x. When these are up to date, the screen you attached should look like this (note the quadrupled RA/DEC step resolution checkboxes and the RA Positioning Resolution that's 4x greater than the one in your shot):
?

What would really be helpful is a screen shot of the physical hand controller screen when you navigate to Menu->HC->Info. This should show something like this (your graphics chip will most likely be different, as my HC is really old):

Re: DEC: Heavy Duty TR alarm - G11
HC fixed...it'll be back to owner soon and we can sort this other issue.?? Though I fell for ye old "I didn't calibrate new screen trick"....so it wasn't responding properly and changed language...then the penny dropped...re-boot and cal screen!?? All good.?? Sigh..been caught by that more than once....Ya think I'd learn by now....but no!

Re: G11 tracking and parking problem
That's what I thought for a long time.?
Turns out, cranking down on the clutches can put excessive loads on your bearings and cause irregular wear on your shaft. It can also mess with your tracking and lead to larger tracking excursions. Super tight clutches can create problems in the long run.
?
I'll see if I can find the thread that discusses it and I'll post the link. Basically I now roll the elevation to zero (with the scope off), then put the scope on, and then balance the counterweights on the RA axis and the fore/aft position on the Dec axis very carefully. Personally I then put a piece of painters tape on my losmandy bar and mark a line even with the center of my Losmandy Mount clamp on the top of the mount so I can easily reposition the OTA. Then I remove the OTA, set the elevation back to match my lattitude, replace the OTA and I'm off to the races.? With a properly balanced OTA, I literally just turn the clutch till it makes contact with the pad and stop, but I'm using Michael Herman's high friction clutch disks. With a clean stock disk you can probably got 1/8 or 1/4 turn past contact and stop. I can easily push my mount around in both RA and DEC without loosening the clutches.? |

Re: G11 tracking and parking problem
Ryan, I do crank down on them. Am I not supposed to do that?

Re: G11 tracking and parking problem
Heads up Art, while it may be contaminated clutch pads, your comment made it seem like you really crank down your clutches. I used to do the same, but best practice is a well balanced scope in RA and Dec with clutches that just make contact.?
A power supply issue or connection issue could also possibly cause an intermittent stop of tracking and if the power comes back on and the position of the mount is anywhere other than CWD there will be significant pointing error which could cause pier collision or failure to find park position on subsequent slews. Check your logs for disconnects.?
occasionally I¡¯ll have tracking errors like streaking stars and I have to return to CWD manually and do a hard power recycle with the switch. This seems to fix it. Usually it happens after using sharpcap for lunar imaging while waiting for astronomical darkness for my NINA sequence¡ it¡¯s like the mount gets stuck in lunar rate.? |

Re: DEC: Heavy Duty TR alarm - G11
Sorry I don¡¯t have MU. ?I Have HC.?? But here is FW flash info screen from HC prior to sending to owner.
?
His HC is giving issues and Display is bad...see here.?? Not sure if the socket issue played a part.....I tried display all dead no response but "splash screen loaded and then boot options".?? But no touch worked.?? I saw the screen...tore it apart...saw the socket.??
?
As said not sure if this played a part but HC does need a display.
?
So the above...kinda moot...till I get a display in.? This crack was present but there is a new one nearby that probably did it in.?? I packed it really well....but who knows.......could have been temp changes or big bad postal....it is what it is!?
?

Doing Screen now.?? Fixing plastic posts cracked....it happens!? Just add to the list!

Re: G11 tracking and parking problem
The temp dropped about 20 degrees F between sunset and when the problem occurred. I suppose the clutche(s) could be slipping even if the knobs are tight. I have had the scope for 4 years. Maybe I should have a clutch cleaning party with the scope. I will play around with it tomorrow while I'm checking into some other things. |

Re: G11 tracking and parking problem
I know my clutch knobs were very tight because I had tightened them just a couple of hours before. I recovered from the problem by restarting the sequence in Nina, which re-centered the target, and I did not have any more instances of this afterwards. I would think that it would have continued and maybe even got worse. But I will certainly double check this.
