Hi All, wondered if you could help me make sense of this ... new HEQ5 - belt modded by FLO, all feels good, minuscule backlash but strange guiding.
Admittedly first time using it but baffled.
Failed calibration see image below and guiding seemed to be Ra and Dec following each other.
Stars look ok ish (@ 1500 mm )
Needle galaxy is poor as only about 10 mins each in RGB
note - it was hazy and did keep losing star in OAG
Thanks for looking
Dear Avalon Enthusiasts,
Do you have PHD2 Guiding Logs that you could share? Preferably at least 30 minutes long.
I am curious about the contribution to the overall error from the individual parts of the belt reduction gear. PHD2 Log Viewer provides nice analysis capabilities for that. I am especially interested in the frequency analysis.
Background is that I have built a motion module that uses a timing belt gear reduction quite similar to the Avalon mounts. Performance is quite good already, but I would like to compare it to the "real thing". 😃
Ok, so this is a really annoying bug / problem that I have with my setup:
From time to time, in non regular intervals the image my guiding cam (ZWO ASI120) send seems to get flipped / mirrored or looks like it's from a completely different patch of sky.
When I'm paying attention to the guide images I can clearly see that the image seems to be flipped in some way.
It only happens for 1 frame PHD send a warning ( No star found / Star lost Mass changed) and after that everything is fine again. My gear is all connected to a single USB3 Hub which then runs via powered USB3 cable to my Pc.
I'm not binning and have the noise reduction off (though PHD might got hickups while processing) but it still happens. Sometimes there are minutes between two events sometimes it happens 5 times in a row.
It also seems like it's only happening during guiding, I haven't seen it happen during calibration yet...
I'm completely clueless what's happening or how to get rid of it, any help / idea is greatly appreciated.
Hi Guys, hoping someone can help me with the guiding issues Iv'e been having. First of all my setup is:
Explore Scientific ED80 Triplet Skywatcher EQ5 mount with synscan Orion mini 50mm guide scope Altair GPCAM2 AR0130 Mono (as the guide camera) I did my polar alignment and 3-star alignment, which was spot on. So I set up the GPCAM2 and opened PHD2 where I selected "Altair Camera" and "On-Camera". It was all in focus, kept it on the default settings and I selected "auto select star", then it said I was guiding (I can hear the mount making small adjustments). A message popped up saying I needed to increase the max RA duration, then I needed to increase the max DEC duration, which I did gradually by 1000ms each time the message appeared. Still no progress.
So I restarted the process with the max RA and DEC duration as 8000ms and it said I needed to eliminate the source of the problems.
(I HAVE ATTACHED IMAGES OF THIS)
I'm not sure why it not working and if I'm doing something wrong. But if someone knows where I'm going wrong, or has any advise it will be greatly appreciated!
Oh and just let me know if you need any more info, because Iv'e probably missed something out.
Thanks again ?
