PHD !!

Recommended Posts

Just started using PHD as cam would not work with 1.2!! 

I am also using a new cam, QHY11-RC and I keep getting 'star lost' between each step W-E and N-S?

I've tweaked a few settings but keep getting this message.

It eventually guides but takes 20 mins+ to calibrate, any suggestions please?

 

Thanks

Ron

Finder, 95% exposures. But I can't even get it to recognise the cam now!

Have you done a full shut down and restart of the lappy.

 

If so you might be as well uninstalling the divers and PHD and reinstall them

Ron my defaults as follows after using the wizard to add a new combination of guide scope and camera:-

Guiding search region 15

Star mass detection (enable) Tolerance 50

Calibration Focal 242 Cal step 900 after pressing calculate.

 

On the main guiding window RA Agr 70, Hys 10, MinMo 0.12, Dec AGR 100, MinMo 0.15 Scope Mx RA 2500 Mc DEC 2500. Some of these are populated after running the guiding assistant.

what are you using Ron ?

PHD 2 ? 

are you pulse guiding ?

have a look on the QHY site and ascom platform site for ascom drivers for the camera, choose the ascom option in camera selection area, make sur you add the focal length of the guide scope into phd brain settings.

Those figures given by the "guiding assistant" for me were a starting point.

 

I am at 80 and 85% agg and now i have done a filp I may have to turn Dec guiding to South only  ( well i have for the last 4 sessions on this target) as it was over correcting even though i had recalibrated

The joys of PHD2 and yes agree as a starting point. For me it worked and ive only adjusted a bit from the original values.

Just running a scan on the lappy then I'll reload the drivers and try again!

That seems better, I'll reset the PHD settings and give it a try!

I use PHD2 now, rather than 1.

 

One thing to consider when you start the calibration is whether you want it to start from it's last known calibration, or whether you want it to reallly start from scratch. PHD, I think, defaults from trying to have ago from a previous calibration.

 

If you want to force a complete new calibration, hold down the SHIFT key, and then click the 'Green target' guiding button. Personally, I always do that once a night initially.

Settled on using PHD 1.44, works great for me.
