Subject: Re: [Astro_IIDC] First light Flea2


Nice full disk image, Jim. I tried to record the sun in white light using the 150ft. solar tower on Mt. Wilson. It projects a 17" solar disk! Even the small sunspot overflowed the 1600x1200 scorpion chip and the seeing was total mush that morning unfortunately. Maybe I will make a film of the dance of the sunspot - at that magnification, it moves a whole lot from the turbulence.


I did have a clear view of the ganymede transit on Friday night using the 16" Meade SCT... not sure how these will come out, but will share when I have a chance to look through the data.


best,

Alan

It was supposed to be clear all night during the Ganymede transit on Saturday morning, but of course it was not. It finally cleared after 3 AM and I just managed to capture some Jupiter data while it was descending behind my neighbour's tree. I'm still working on that data but the Flea2 seems to be significantly less light sensitive than the Flea despite both having the same Sony ICX204 ccd. Any thoughts on that Milton?

Anyway, here's the Sun from today, lots of activity.
