Big JUPITER from the archives 18 Feb 2006

Hi All, DP's recent comparison of images scale of some of the better shots prompted me to dig out one of the avis I did on Jupiter with 4x powermate on the night of good seeing back on Feb 18. I tried processing these at the time, but couldn't get the same detail as with the 2.5x shots.

Had another go. WIth the F12 Mewlon this is around F50. I think it's too much for the light collecting capacity of the 7inch and the image breaks down, but it gives a good idea of what the image scale possible with my setup is. Hoping for anther nights good seeing to try the 4x powermate with the C9.25 - more light and a more manageable F40.

cheers,

Hey that's pretty good for the image scale, Robert!

It's only a tad soft due to the seeing. On a night of great seeing, it will be fantastic to see you pull out a ripper with that scale.

thanks rob,

as you said, the 2.5 gave you better detail.

I really want to be able to put a damian peach / chris go / bird image scale into perspective.

I remember seeing a recent chris go image and thought "nothing special". Rescale it back to our normal size and the imperfections disappear.

What made me start thinking was watching yours and dennis videos and thinking that they are around 2/3 of the size of mine on screen.

As Ice says, hopefully the months ahead will get some great seeing again for you guys and a f40 - f50 crystal clear image is on the cards.

Of course I am assuming that chris and damian aren't resampling

I have added your latest one to get a feel for the scale

Robert that's great, I even like it as is to tell you the truth.
Will be interesting to see how you go with better seeing though.

Thanks for that.

DP, i'm 100% certain that Chris and Damien are both resampling. They just have great seeing and lots of frames for the resampled big version to still look very detailed.
