Third attempt at Jupiter

[CThody]

I took this through a Nexstar 5SE using Celestron Neximager and a 2x Barlow. Then processed through Registax. It's the best I've managed so far, but would like to get sharper detail. Any advice very welcome.

I find focussing on a laptop screen the toughest thing to do...

You can edit image levels (PS, Gimp...) and move the left slider close to the signal peak. It will remove/reduce the background grey noise. As for the image - it looks bit blurry, like badly aligned frames or not perfect focus. Hard to tell.

Thanks for your reply...

Re You can edit image levels (PS, Gimp...) and move the left slider close to the signal peak. Where do I find this on Registax? Also I think it is more to do with the focus than anythiong, but really can't find a way of getting pinsharop focus on a laptop screen. Any tips?

Levels aren't in registax. You can find this in Gimp or Photoshop. As for focusing - I focus looking at the screen. For stacking the square should be bigger than the planet.
