Re: Saturn: the calm before the storm!

Unbelievably good. Just imagine, 20 years ago even space probes didn't take shots as good as that!

First Saturn Image - advice wanted

Posted By Greg Bradley
Here is my fist Saturn image using a ToUcam and FS 152 scope.

I had it set as follows;
Image controls set to;
25 frames per second
brightness about 40%
saturation -full,
gamma - zero
contrast 50%

camera controls set to;
gain zero
shutter speed 1/25th sec.
auto white balance

It was 3900 frames.

Processed using planetary wizard in K3CCD tools.

Suggestions? It seems not that sharp yet the visual view was stunning and excellent seeing.

TV 2X barlow used as well.

Thanks Greg.

Re: Best Opposition Saturn

Posted By Greg Bradley
Oh my god that is stunning!

Can you tell me how you did the shots? Luminance shot, what does that mean?

Did you take separate shots with the diffent colour filters?

Best I have seen, well done. Looks like a NASA shot.

Hi Eric,

Can you explain to me how you get your scope to F39?

Is that a 5X powermate or something? Do you mask your corrector plate?

Thanks,

Greg.

Southern Cross from Vanuatu

Posted By Greg Bradley
Just been to the incredibly beautiful South Pacific Island Paradise - Vanuatu. Clear skies so took some shots of the Southern Cross and Crux Area. Coconut trees in foreground.About 75 degrees F, tropical island with lush vegetation and coral reefs.

Nikon D70 50mm Nikkor F2.0 lens, ISO 1600 20 seconds 1/3rd moon, single shot, processed in Nikon Capture Editor software.

The Southern Cross is the 5 star pattern to the bottom left, it is the most well known star pattern in the Southern Hemisphere and is on many nations Flag's. You can work out due south from it.

Small Magellanic Cloud

Posted By Greg Bradley
Small Magellanic Cloud is actually a tour in itself with a large enough telescope. There are something like 15 globs in there
and nebulas as well!

Nearby is the fabulous 47 Tucanna glob, surpassed only by Omega Centauri and in some ways a better visual target as it has a very bright core.That is 47 tuc at the bottom of the shot.

Nikon D70, Nikon 180mm ED F2.8 lens, Dark site NSW Australia, Jan, 3 x 30 sec, ISO 1600.

Both the large and small Magellanic clouds are visible to the naked eye at a dark site as a white cloud. The LMC is quite large.

This shot shows some star trailing whereas the same length shot of the LMC shows much less. The LMC is close to the South Celestial Pole, perhaps that is why.
