My Best Jupiter so far.

[Astroman]

Hi all,

My best Jupiter so far. Taken in a very small window of 7-8/10 seeing. Occasionally a 9 would pop in and you could see detail on the raw frame. Taken with a 200mm f6 newtonian. Asi120mm. 145mm extensiom tube. With firecapture. Processed using AS!2, Registax. I took 50 x 60sec videos at 56fps, this was one of the first ones.

Nicely done from a very modest telescope :)

Good work Andrew along with an impressive image scale.:thumbsup:

Cheers

Thaks guys,

Still trying to work out why Io is a line and not resolved as a star or disk... might be the stacking process maybe?

Awesome Andrew - Jolly Jupiters :clap:

Were there any alignment points on Io - depend stack prog, ? Assume all planet stack prog should have align points :thumbsup:

Hi Andrew

The “elongated” Io is likely due to the orbital motion of the moon during the image capture process. I once recorded a 90 sec AVI and Io was elongated and I could just detect a smearing of finer details on the disc of Jupiter due to the rapid rotation of the planet.

I understand that the more advanced planetary astophotographers use an application called WinJUPOS to allow them to “de-rotate” long AVI’s so that the surface features are not smeared.

Cheers

Dennis.

Yep, cheers Dennis, your onto it, id say :thumbsup:

Does the fast frame rate stop blur from atmospheric 'boiling' during capture? Is that a factor in your thinking?

Cheers
