Hi all,

I've been trying to get my ducks in a row for next week's transit of Venus, testing my new PGR Grasshopper Express streaming camera with 6 megapixel sensor with Astro IIDC. Connected to my 90mm refractor extended to a FL of .9 meter, this camera will capture the full disk of the sun in one capture stream. Here's a test image from yesterday's sun:

This was in moderate seeing. Good seeing should provide some real fun. 

For the small screen, here is the image reduced to 66%:

Hoping we all find some clear, steady skies next Tuesday!

Alan
