Jupiter with an undriven dob -2x barlow

Recommended Posts

My latest efforts with Jupiter higher in the sky now.

You can see a moon shadow and a few markes but its still fuzzy. Perhaps due to the undriven set up and only having about 20 seconds as the planet flies accross the screen! :)

A couple of things strike me.

1. Saturation=0, try it at a relatively high setting (I have mine at max)

2. Gamma=21, try it at 0

I have no idea what Exposure=-6 means in terms of a time frame?? but you may be able to reduce the exposure a notch and bump the gain up a little. You should be able to still get a sharp image with a dob but will be a bit limited by the total number of frames you can capture. If I were you I would also experiment with 20fps :)
