This is one of my very early
attempts at trying to capture Saturn.
As this image shows, it does not pay to over process as you will
introduce all sorts of markings that are not really there to start
with. Also note how wide Cassini division is. In reality
this is a very small dark band not as wide as this.

Captured
with K3CCDTools at 10 frames per sec.
Gama 0. Saturation 100. White Balance auto.
1/25 sec and Gain at around
30%
Telescope was the 8 3/4 f/7.2 Dobsonian.
100 of the best frames stacked in Registax and wavelets 4,5 and 6
raised by
3,9 and 8 repectively.
Saturn-191204-imagemate is X4 barlow lens. |

Saturn-2X2-TV-191204 is the 2X2 teleconverters.
This image I think just has an edge over detail etc. The night
was not the best for imaging as it was misty and windy. |

This
mosaic of Saturn was produced all on one night, some 4 hours
work. Each image is from a 1 minute AVI at 10 frames per second
captured with
K3CCDTools. Stack frames in Registax 2 using the top 80%,
this amounted to around 500 frames.
White balance auto.
Gama at 0.
Saturation at 80%
1/5 shutter
Gain at 25%
There is a lot a colour and detail variation between all the
images. Just goes to show how the sky conditions can change and
what a difference this can
make to the final image. |

Saturn taken on the
21st April 2005 using a 222mm
Saturn is again taken from an avi of 90 secs at 10 frames per second
but this time only 224 frames were good enough for this image. |
ToUcam
|
Captured on the night of 29
April 2005.
Saturn is 181 frames from a 600
frame AVI again of 1 minute.
Captured with K3CCDTools.
Auto white balance. 5fps. Gain 15%.
It still came out very bright but darkened slightly when I applied
the
Wavlets on layers 4,5 and 6.
Processed with Registax.

222mm Newtonian with X4 Barlow.
Captured using K3CCDTools. 90 Second AVI at 10 fps. Auto
White. Gama 0 and
Saturation 100. Auto Colour balance for 5 seconds until colour
settled then
un-ticked it.. 1/25 Shutter. Gain around 60%.
Top 20% (Lowest Quality 80%) of 900 frames stacked in Registax.
Wavletes 3=6,
4=11 and 5=16. Tweaked the blue (lowered) Levels in Gimp.

Also got my first image of Saturn for 2005 at 0230UT.
This image is the best 20% of 200 frames. Captured as .bmp's and
stacked in Registax.
Setting used were auto for most but the timing and Histogram.
0.380 Timing and I raised *moved to the right) the white slider till it
was around 50,000 to stop the white areas from saturating.

Not a good night as far as mist is concerned. The fog/mist seemed
to spread out the blue channel.
Used Auto colour and white balance. 1/33rd Shutter speed.
Gain around the 5% mark.
90 second AVI. Top 30% used in the stack in Registax 3

21st January, 2006
Started out to be not a good night with a high mist spreading the red
and blue colours.
Captured 90 second AVI. Auto white and colour balance. Gama
20% and Saturation 50%.
1/25th Shutter speed and Gain at 40%. X4 Barlow on the 222mm
f/7.92 Newtonian.
Tweaked the colour balance in the Gimp and X2 enlarged.

Another misty night. I used the same setting as above.
Looks like I am getting close with the collimation. I use a laser
collimator then tweak the primary using a star out of focus.

SC3 RGB

4th March, 2006
Captured 30 seconds of each colour RGB and stacked the best 200 frames of each colour. Aligned and Curves tweaked in Gimp.

SC3 IRL-RGB
|
4th March, 2006
This image is the same as the one just above but here I have added a
luminance layer on top of the RGB. The IR luminance layer is also
the best 200 frames from a 30 seconds AVI 10 fps.

9th February, 2008
Tonight was misty but the planets were on show and seemed steady in the eyepiece.
Here is a DSI image using my 8" f/6 Newtonian with a X4 Barlow lens.
Setting the DSI to capture the planets is very difficult as the
settings have to be lowered so much.
This image is 160 frames captured as bmp. Gain was around the 5%.
I opened the Histogram so that the black pointer was all the
way to the left and the white pointer was all the way to the right.
Used auto white/colour balance. Stacked in Registax and
final tweak in the Gimp. |

9th February, 2008
Same night, telescope and X4 barlow lens but this time I used the
ToUcam. Settings used were Gama 0% and Saturation 100%.
1/25th Shutter speed and Gain at 30%. Auto colour and white
balance. This is 400 frames from 600 frame AVI.
Stacked in Registax. |
