Well, as luck would have it, I did manage to record the “once-was-a-planet” Pluto during the same session.
This was a test shot just after setting up, to check focus, exposure, etc. and I just pointed the camera up and grabbed a 30 sec exposure. As you can see, the Dew Heater Strip is encroaching into the FOV at bottom right, so I re-positioned it for the live run later. The stars are quite distorted at the edges as expected.
Just goes to show what you might find in your set up/failed shots - think twice before pressing the delete Button.
How do you explain to Clyde William Tombaugh that using modern equipment, I recorded the position of Pluto with a 15mm wide angle lens and a single 30 sec exposure…
I have attached a screen print from The Sky showing the FOV and target locations.
Unfortunately, I cannot include this shot in the original composition as the FOV and orientation don't match.
Cheers
