PHD2LogViewer Advice
« on: 19:56:56, 23 July, 2015 »
Hi,
 
So i took the plunge and bought an Orion starshoot autoguider and 50mm guide scope.

PHD2 seemed to guide ok, before things went wrong - it kept telling me my RA/Dec duration ms was too short, so i increased it and increased it...
 
I downloaded the PHD2LogViewer and had a look at my guiding log
The only trouble is, i have no idea what it means. Its all numbers to me...
 
I've attached a few of screenshots where things seem to go awry. Included are calibration and guiding shots. I changed target and so recalibrated part way through. Issue maybe?
 
Any ideas on how to solve? Or even what it means?
 
Maybe the log file would be easier to attach?
 
Thanks
Joe

Joe

Are you sure the focal length of your guide scope is 50mm? What are you using? Seems very short and results in a guider scale of 21.45 arc seconds per pixel which is pretty coarse.

Hi Chris

It's the orion magnificent mini guide scope package. I think it's the aperture that's 50mm

Cheers

Yep 162mm focal length. Putting the correct focal length into PHD will make a big difference; the pixel scale becomes 6.6 as compared to the 21.45 you had.
