ASI290MM Error Msg - Failed to get properties for ZWOASI Camera

[rjk...@zoominternet.net]

I receive an error message - (Failed to get properties for ZWOASI camera) when trying to connect a ZWO ASI290MM camera to PHD2 rel 2.6.2 using the ZWO driver. The camera connects properly to PHD2 using the ASCOM driver. The camera also connects properly to several other capture and guider software with the ZWO driver so I think the ZWO driver is working properly, I tried the same driver on three different laptops running XP, Win10 and Win10 Anniversary respectively and receive the same error message. Any help would be appreciated.

Thanks, Bob

Hi Bob, Could you please attach your PHD2 Debug Log.  (Instructions here)

I have the exact same issue with my ASI290mm. Have you been able to resolve this?

Kind regards,

Andrew

Andrew,

Are you using PHD2 version 2.6.2dev4 or newer?   That version was should work with the ASI290MM.  If not, please post your PHD2 Debug Log.

I'm still fighting poor guiding and I'm using a  AS290mm.  Starting to wonder if it's the camera and I found this thread by googling the problem.  Chris Woodward has suggested I'm way undersaturating my guide star... when in fact I'm constantly told my star is over saturated.  Because of this I have had to try my (PHD2 camera gain setting as lot as 0) to eliminate the "SAT" error and flat top star profiles? 

I haven't had clear skies (Won't until Jan probably) to test deliberate over saturation... but when I started in the hobby last May... I had my best guiding ever with my NEQ6.  As people saw my screen capture they pointed out that my star was over saturated and at that point ( learned what SAT was) I then started reducing PHD exposures to 1 second to reduce star exposure.  Being told I should be using 4-5 seconds. (I'm now upgraded to a Mach1) that surely over exposes the star and I'm forced to really reduce the gain setting. (yep to 0 at times).  No matter where I have gain set, I tell PHD2 to auto-select star.  And it always seems to pick an extremely weak star. 

I'm anxious to test an overly saturated star to see if this is my problem.  But finding this thread made me curious.   IS ANYONE getting good guiding using PHD2 and the ASI290mm?

P.S. to my previous post.  I have no need (noticed) this 290mm error? mine just connects. I have recently updated to the latest dev4 release. (btw).   I've been tearing my hair out since May.

Hi Ron.  It would be better to open a new forum topic at this point, it’s pretty unlikely your problem has anything to do with the year-old thread.  More importantly, we’ll need to see a recent guide log so we can analyze what’s going on.  If your problem is poor guiding, there are many possible causes, of which star saturation is one of the less common.  As far as auto-star-selection goes, the current releases will usually do a better job of that than the average user can.  What you see on the display is affected by the screen-stretching – the gain slider on the main display.  The auto-select function is looking at something different, the full-range, unstretched data from the camera.  So what may look like a poor choice is often a perfectly good one.  Since this will probably be your first time on the forum, why don’t you also submit the matching debug log file – especially if it includes an auto-select operation that you subsequently rejected.

 

Instructions for finding the log files are here: https://openphdguiding.org/getting-help/

 

If the debug log file is very large, you can use a file-sharing service like DropBox, then post a publicly accessible link on the forum.

 

Once we can see all the data, we should be able to give you some help – the Mach1 mounts usually behave well.

 

Regards,

Bruce

+1 on using auto star selection to find an appropriate star that isn’t oversaturated or low SNR

 

If you are concerned about that just hit alt-S and let PHD find the best guide star for you

 

Thanks
