+RonC Posted August 31, 2018 Share Posted August 31, 2018 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 Link to comment Share on other sites More sharing options...
+Ibbo Posted August 31, 2018 Share Posted August 31, 2018 How are you guiding -finder guider or OAG? what exposure have you used ? Link to comment Share on other sites More sharing options...
+RonC Posted August 31, 2018 Author Share Posted August 31, 2018 Finder, 95% exposures. But I can't even get it to recognise the cam now! Link to comment Share on other sites More sharing options...
+RonC Posted August 31, 2018 Author Share Posted August 31, 2018 Working OK on PC but problems on the lappy!? Link to comment Share on other sites More sharing options...
+Ibbo Posted August 31, 2018 Share Posted August 31, 2018 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 Link to comment Share on other sites More sharing options...
+RonC Posted August 31, 2018 Author Share Posted August 31, 2018 Just doing that Steve! Link to comment Share on other sites More sharing options...
Alec Posted August 31, 2018 Share Posted August 31, 2018 Ron my defaults as follows after using the wizard to add a new combination of guide scope and camera:- Brain bottom of page:- 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. +RonC 1 Link to comment Share on other sites More sharing options...
red dwalf Posted August 31, 2018 Share Posted August 31, 2018 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.

+Ibbo Posted August 31, 2018 Share Posted August 31, 2018 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 Link to comment Share on other sites More sharing options...
Alec Posted August 31, 2018 Share Posted August 31, 2018 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. +Ibbo 1 Link to comment Share on other sites More sharing options...
+RonC Posted August 31, 2018 Author Share Posted August 31, 2018 Just running a scan on the lappy then I'll reload the drivers and try again! Link to comment Share on other sites More sharing options...
+RonC Posted August 31, 2018 Author Share Posted August 31, 2018 That seems better, I'll reset the PHD settings and give it a try! Link to comment Share on other sites More sharing options...
+Ibbo Posted August 31, 2018 Share Posted August 31, 2018 Connect cam input your focal length of guide scope etc and run guiding assistant Link to comment Share on other sites More sharing options...
+RonC Posted September 1, 2018 Author Share Posted September 1, 2018 Thanks Steve, discovered it was mostly the laptop that needed sorting out!! Will try again asap. Ron Link to comment Share on other sites More sharing options...
+Derbyshire Dave Posted September 4, 2018 Share Posted September 4, 2018 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. Link to comment Share on other sites More sharing options...
+RonC Posted September 14, 2018 Author Share Posted September 14, 2018 Settled on using PHD 1.44, works great for me. Link to comment Share on other sites More sharing options...
Alec Posted September 14, 2018 Share Posted September 14, 2018 PHD 2 is working fine for me once I sorted it out Link to comment Share on other sites More sharing options...
