Yesterday I was photographing sunspot group 1302 through my Coronado PST when wild geese flew in front of the Sun...

here is the link to animation (~2,5 Mb)

Tere.

Very nice! Also that yellow circle looks very detaily...
Soo, you could calculate the distance of the geese if you take their size like some average?
Is this picture in mirror, or you are looking the Sun in the morning?

Can't wait until I can start staring at the Sun

Coronado PST Cant bring my self to buy one. I really want a H-alpha OTA but they are way too expensive.
I am probably going to pick up the Herschel wedge next year.
What camera do you use?

Thanks for looking, it's just the begining... I have a lot of videos to process from that day.

Thanks. It was completely unexpected.
I've made some calculations, and found that the distance was approximately 1,8 km (assuming length of the goose ~1 m).
I captured the video at 12:58 local time, celestial north is (approximately) up.

I use Basler acA640-100gm monochrome CCD.
As to the Coronado PST, I love this scope. It was bought in the USA with a help of my friend, the price is the lowest there.
