Afocal Jupiter and accidental shadow transit

Inmykombi (Geoff) · #1 24-10-2009, 12:28 AM

I was practising the Afocal Method on Jupiter tonght in pretty poor seeing, when I noticed a shadow transit so I kept on "clicking away "

I tried a new Samsung compact camera instead of my usual Canon.
I think the Canon has the edge over this one, but time will tell.
I also used an afocal bracket which attaches top the eyepiece to hold the camera steady.
My 10 inch LX200 through 20 mm eyepiece 1/2 digital zoom on the camera and a little processing to drop the brightness down a bit.

I'll keep practising to see how far I can go with this method in good seeing perhaps.

Thx for looking.

Not too shabby at all Geoffro, concidering how bad the seeing was.

There's detail between the bands which is good.
Nice nab on the shadow transit as well.

Try not to use the digital zoom, it can/will degrade your final image.

No Zoom....Geee whiz, a man has no secrets........

I have tried many different ways, and you are spot on with that advice. This one was the best of a bad bunch in poor seeing. The cloud cover also made it difficult. Anyway its all fun.

Thx for looking.

Optical zoom is fine, great, perfect, couldn't do without it.
JUST NOT DIGITAL ZOOM.
