Interesting way to look at the sky

Today, I moved my 12" dob to the Control Room Shed.

I plonked it down and could see a faint dot of light on it. Though nothing of it.

Then Harry came in and shut the door.

BINGO!!!!!!

There on the side of my scope was an image of the Sun being covered by moving clouds! It was beautiful. Me and my 2 sons stood there watching it for about 10 minutes!!!!!!!!!

A small nail hole in the wall of the shed was casting the image onto the OTA!

1. The OTA were it was placed. With Flash on (can just see the dot of light)
2. With the door shut and no flash. See the sun and clouds image!!!!

That's amazing Ken!

An awesome bit of coincidence - and even though one immediately understands the science behind why it happened, that takes nothing away from the beauty and magic of the moment.

Exactly, Steve.

We know it is pinhole camera projection, but Geez, it still fascinates me when I see it happen, and my boys were thrilled !!!!

And the pics don't do it justice. It was a beautiful 'in focus' full colour image right there on the OTA with slowly moving clouds.

Sleep is what is done between 5am and 11am if the chance arises

. . . and the Tube makes a great Water Heater outer casing replacement

And I'm sure our wives would love the Mirror for applying make-up, plucking Eyebrows etc

Very handy appliances, these Dobs!

Beware, you'll be bombarded by questions like: "Does this mirror make my face look fat?"

Good value Ken, sometimes the simplest images can be the most fascinating.

Cheers
