cem60 meridian flip #38063
learning the ropes of automated capture.....

CEM60, PHD2, Moonlight

(1) EKOS initiates the flip when arriving at the threshold, but does not wait for the exposure to end
(2) EKOS does not trigger a platesolve after the flip
(3) PHD2 does not know a flip happened, and DEC control goes off the rails, regardless off the "reverse the DEC output" setting...

I don't seem to be able to find the right combo of settings, even tried to use internal guiding....

If you have any idea, or have solved a similar issue, please share!

I just started my observatory to test this (but with internal guiding). I uploaded a video so you can see all the settings..etc. It all worked fine.

thank you Jasem!
Funny, but watching your video is just as nerve-racking (in a good way) as working my own equipment. that sure was a success, but I saw you (like me) kept "autofocus every nn minutes" unclicked...

anyway: really enjoy the program, and certainly the interactions with you, and other boarders. I just feel a little like a parasite, and wonder what I could do to help the project...

Thanks again

Michael

I have yet to test it with PHD2 however. So this could still be the factor of the issue here.

cem60 meridian flip #38291
Worked perfectly last night, and I was running under PHD2. Have not found the right settings for the internal guider yet....

I believe my mistake was to let the mount (CEM60) initiate the flip at the meridian, so I put the point where the mount flips 10 degrees past the meridian, this obviously gave EKOS priority . Post flip alignment also worked great, and EKOS finished the series wonderfully.

Next step will be to get autofocus to work post flip....

Thanks Jasem!

Tried again, but failed the last 2 nights.

Was watching "live", and believe the problem was created when the solver started before the mount was even reaching the pole. Alignment module tried to solve to another Nebula, I assume to the one the mount was flying over when solver started prematurely. Another platesolve was successful, and the mount slowed from my intended target M66 , "flipping back" to somewhere near the pole. Subsequently I stepped in and slewed the mount back to M66, and initiated another platesolve: Once this was successful and complete, EKOS started the new calibration of PHD2, and once that was complete it also commenced with the acquisition.

Below is the solver comments during that flip:

2019-04-25T22:28:56 Target is within acceptable range. Astrometric solver is successful.

Try increasing the SETTLE value, to 3000 or 4000

Thanks, will try and let you know.

On a side note, re: autofocus module post flip: I left "subframe" unclicked this time, and it completed "successfully": the system shot about 10 frames, 9 returned a HFR of 3.0, one 2.75, so that's where I ended up. I am not sure that this was ideal focus though, any words on wisdom on that issue?

Thanks
Michael

is that what you usually get at best focus for that star?

This autofocus procedure ran with auto select star, full frame, and subframe all deselected. but based on the time that it took -several minutes for 10 iterations- I think (insert standard newbie disclaimer here) that this was a full field evaluation. at my FOV (35'x25') M66 does not have an abundance of stars around, which IMHO makes this target a good object to test "no - subframe - autofocus" after meridian flip.

I found the uniformity of returned HFR values interesting, the "v-curve" was a straight line, and without deeper understanding of the algorithm I am a little suspicious of the result.

Thanks Jasem!
