It's never as good in a photo as what you know you saw through the viewfinder, but this is very good.

I remember reading of a technique a group had developed where they used a webcam and custom image software in order to pick out individual frames that were much sharper than the rest, and then compiling them into images that were stunningly sharp.

Roger Powell on July 16, 2013

Yes, Tom, that's right. This was taken with a DSLR attached to the telescope but I have tried using a webcam in place of the telescope eyepiece and stacking selected frames.
Thanks for the comment!

That is a good photo. I'm wondering however where are the moons? Io is my favourite moon.

Roger Powell on August 3, 2013

It's a matter of getting the right exposure. Jupiter is hundreds of times brighter than the moons. This image exposes Jupiter correctly but under-exposes the Moons so they are not seen. Generally, an image would have to greatly over-expose Jupiter to capture the four bright moons. It is possible for one image to be superimposed on the other to get a perfect shot of Jupiter with its Moons.

Thanks, Chaydeé I'm glad you liked it (and learned something)! I take a lot of astro-images but I don't post very many here on Panoramio.

How many x magnification is this Roger? Lk it..

Roger Powell on October 8, 2013

That is a very good question - but one I cannot answer directly. It depends on how big the image is on your computer monitor and how far your eyes are from the screen. I can tell you that Jupiter would have been 45-50 arc seconds in diameter to the naked eye at the time the image was taken, which is about 1.3% of a degree, an exceedingly narrow angle of incidence.

If the apparent angle to your eye of the image on the screen is, for example, 2.6 degrees, that would seem to give you a magnification of 200x
