Hi Rolf,
I hadn't really noticed across the frame differences but to be honest I didn't really
look at it.
Now that you point it out, I always image NGC 2822 with the galaxy itself centred in the shot and Miaplacidus down in the bottom right corner.
As you can see the spikes still look reasonably sharp. Food for thought, maybe on a good,
steady night I should do two sets, the second with Mia centre of frame.
I love your secondary dew experiments, just read it!
I was only thinking last week about your guitar string arrangement and thinking to myself
I wonder if Rolf eve thought of using the strings via some insulators as a way of getting power to the secondary! Then I thought, no, I bet heat would be a problem! Funny stuff!
I did try 4 thou feeler but it was too thin even under tension, showed flex when the OTA was moved from zenith to other orientations, 10 thou/0.25mm seems to be the
compromise.
Great to see amateurs sharing ideas , thumbs up!
Steve
