Thanks so much for all your help with getting started with PHD2. I used it for the first time under the sky last night and, at the end of the imaging session, I took a 10 minute exposure of M64 with PHD2 managing the guiding.
Here is the result: https://www.dropbox....0001_3.CR2?dl=0. I'm quite excited.
Not much in the way of star trails as far as I can see. In terms of setup and process, however, I'd like some advice. This is on a CEM70 mount; 80 mm Stellarvue refractor; Cannon EOS t7i camera; 800 ISO/10 min exposure; 50 mm guidescope; ZWO 290 mm guide camera. I hooked the camera into my HP laptop via USB. Hooked the laptop into the mount using a USB cable also. Used ASCOM software set to manage the CEM70. I slewed the scope to M64.
Initially, I had trouble achieving focus of the guide camera. I had to use the extender and pull the camera all the way back until it almost fell out. How important is focus? Is there a different way to achieve focus than pulling the camera forward and back and then using the screws? Anyway, I then looped the images at 1s exposure and auto selected the star. I hit the green circle button and it started to calculate the whole West, East, Backlash etc. All the while the star moved away from the crosshair center and then moved back. After a while, the lower field read "guiding" and the graph started to generate the red and blue lines. Those lines were really wild with each hump basically going from the center line to the top and bottom of the screen! But the guiding seemed to work. I used all the default settings.
How do I get a log for you guys to view? When I go into the open log window under HELP, I can only see three EXPLORER files that identify failures to lock onto the autostar selection (something that happened at the very beginning of the imaging session before I had focus).
Any suggestions on what I have to look out for and how to bring those "humps" down closer to the centerline? I hope I wasn't chasing the seeing.
I must admit that I'm blown away by how sharp the stars are in that 10 min exposure. The CEM 70/Stellarvue typically gives me 3 minutes of unguided imaging with minimal star trails. But 10 min would be impossible.
