Hi,
I recently realised that I deleted my factory shipped PEC training from the my new CPC1100 using the PECTool software. This was done when I eagerly downloaded all the software form the Celestron Site that had anything to do with the CPC and without reading the manual first, put it through an 8 minute training cycle with the clutch undone, so now when I download the PEC data it's just a straight line along the bottom of the graph. Apparently if I had saved it first I could have restored it again :ashamed: woops!
My understanding is that PEC will only work when set in EQ mode and not Alt-Az?
So I understand now that I have three options....
- With a high magnification reticle eyepiece and the hand control - You can use rates 1 and 2 (photoguide rates) on the hand control to manually keep the star centered for 8 minutes.
- With a high magnification reticle eyepiece and a drive corrector unit - You can use a device that plugs into the autoguider port to move left/right to center the star while training.
- With an autoguiding CCD camera - Find the worm index, then autoguide on a star. Train while autoguiding to record the corrections.
Has anyone had success with the first manual option? is it actuate enough? Could I use my Hyperstar and EOS 550D in +5 or +10 zoom in liveview with good results? or do I need to setup the EOS using Primefocus? or am I going to need to purchase a "high magnification reticle eyepiece"?
Or will I need to get an Autoguider before I can resolve this to a satisfactory level?
:help: :D
