noisy and unnecessary, as Jupiter is bright. I suggest using 800 and start
with around 1/10th sec. Enlarge the resulting image to maximum on your
LCD screen, examine it, and shorten or lengthen your exposure as necessary
for each ensuing attempt until you get it right. Have you not got a lens
longer than 50mm?

Thanks Raymo. I did try photographing the moon last night as well and dropped the ISO down to 800 but all I got was a bright blob....lol

Right! My plan of action tonight is to drop the ISO down on Jupiter and try different exposure lengths.

I do have another lens and it 70mm-300mm. Would you suggest using that?

Annoyingly, I did have really good focus on a nice bright star but then moved that focus when I decided to do the Milky Way. I thought afterwards I should have left the focus alone!

Still learning and it is getting clearer to me but I need to think more!!

Thanks guys.
