Mid, I know earlier in the year I asked you general questions about what could be visible at various focal lengths but I wanted to get more specific.
My question is can all three of these be captured with a superzoom camera at 2,000mm EFL (Nikon P900/950.)
1) Cassini's Division in Saturn's Rings
2) Great Red Spot on Jupiter
3) Martian Polar Ice Cap on Mars
I think the answer is yes, they can be captured (barely) with the P900/950 at 2,000mm EFL but much more easily captured (NASA like) with the longer zoom at 3,000mm EFL with the P1000.
Here is what I've found in images with the P900/950:https://commons.wikimedia.org/wiki/File

This picture was taken with the P900 and shows Jupiter and it's main moons, you can see the Great Red Spot at the lower right and a shadow of Ganymede, the largest moon, on Jupiter.https://www.dpreview.com/forums/thread/4029136
Further down in the thread my favorite Saturn images taken with the P900 from Aisse and MarioV (his was a single image unstacked, and you can make out Cassini's Division barely, but it's there.) Aisse's images of Jupiter and Saturn show the Cassini Division and Great Red Spot much more clearly (like NASA photos) but both can be captured with the P900/950 also. Can this be backed up by mathematical calculations that prove you can see all three at 2,000mm EFL on those cameras?
And here is one I found with the polar ice cap on Mars.https://www.dpreview.com/forums/thread/3975229https://www.dpreview.com/forums/post/57390620
Mario V also includes images of Jupiter and Saturn there.https://cochinblogs-hobby.blogspot.com/ ... t-max.html
Very descriptive features on Mars that are captured.https://www.dpreview.com/forums/thread/4472826
So it looks like at a minimum you need a 2000mm EFL to see the Cassini Division on Saturn's rings, the Great Red Spot on Jupiter and the Martian Polar Ice caps, but all are much more clearly visible on the P1000 at full zoom.https://www.dpreview.com/forums/post/64440618https://upload.wikimedia.org/wikipedia/ ... -07-24.jpghttps://www.dpreview.com/forums/thread/4029136https://www.dpreview.com/forums/thread/4472823https://www.dpreview.com/forums/thread/4182798https://www.dpreview.com/forums/thread/4275373https://www.dpreview.com/forums/post/64393206https://jzholloway.wordpress.com/2020/0 ... njunction/https://cochinblogs-hobby.blogspot.com/ ... t-max.htmlhttps://cochinblogs-hobby.blogspot.com/ ... t-max.html
