Saturn 03/06/15 Variable Seeing.

[PJW66]

  Started imaging around 11:30pm  with the planet hanging over nearby chimneys. The seeing would be ok one minute,then really poor the next. Decided to lower the framerate down to about 18fps with the gain set at 57 in Firecapture,and exposure around 40ms.Histogram was touching the 50% mark most of the time. This run was 6 minutes 26 seconds with around 7500 frames.Best 65 % stacked with 1.5x drizzle.Used AstraImage 3 and Image Analyser for deconvolution and selective noise reduction. I'm really happy that this has turned out quite nice considering the shocking seeing i was watching on my live feed! 

Cheers,Phil

Some good detail coming through Phil despite the poor seeing. Its a bit bright on my monitor and I would be tempted to lower the contrast a little.

Thanks Alan.
I deliberately set the capture on the bright side thinking it would reduce noise but i may have overdone it!

Nice one Phil, Saturn came out well.

[PJW66]

Cheers Robin. i'll probably make it my last Saturn post unless i can catch some really good low elevation seeing.

Saturn is a tough target again this year so that is a very good end result

U have done well there.

Thanks everyone who commented.
I may try slightly more magnification if i can get reasonable seeing in the next few weeks. At the moment i'm imaging @ F17 but i'm thinking i could push it a bit to F20-F25 . I know the ASI120 works best below f20 but i'll see how it goes one evening.

Cheers,Phil

That's a great image Phil.

Great image tim.Lovely detail in there

Very nice, I've been trying lower gain with slower frame rates against high gain and faster frame rates but not really seeing much difference between 40% and 80% gain ...

Yours has come out nicely
