Hello to all,
It would be great if any of you can give some insight on how to solve my current problem, which is that I cannot achieve round stars in exposures longer than 3 minutes. Less than that, I get round stars. First of all, my setup:
Imaging scope: Meade SN-6 (762mm FL, f/5)
Imaging camera: Atik 314L+ CCD
Guiding scope: Celestron TravelScope 70 (400mm FL, f/5.7)
Guiding camera: Orion SSAG (with GSO 0.5x Reducer threaded directly to 1.25" nosepiece)
Mount: Orion Sirius EQ-G
I am attaching my PHD Guiding Advanced Settings, hoping that anyone can suggest any changes to the existing parameters. I consider my polar alignment good, and use the 3-Star Alignment option. With these parameters, the guiding graph in PHD looks very good, without big spikes or strange jumps. Both RA and DEC lines look fairly flat and smooth.
Let me add that using these parameters, I can achieve 10 minute exposures (more than enough for me) using my William Optics GT81 (478mm FL) instead of the Meade SN-6, and my 50mm finder guider instead of the TravelScope and GSO Reducer.
Any help will be very appreciated.
