Mars 22.8.2003, 01:48 (21.8.2003,
23:48 UT)
Distance from Earth: 0.375 AU (56 million km)
Diameter: 24.97"
Altitude: 25.8° above horizon
Resolution: 0.32 arcsec/pixel
Telescope: 8" OrionOptics Newtonian (f=1200mm)
Camera: ToUCam Pro+ Barlow 3X, Baader IRB filter
Result focal length: 3600mm
Exposure: 375x1/25s (gain 05%)
Seeing: clouds, steady air, 19.5°C, humidity 67%
Processing: K3CCDTools
+ Registax 2.0 + Corel PhotoPaintThe first
light of my new ToUCam Pro webcam. It is very
unstable with my laptop and I had to restart it
several times during astrophoto session.
Inspite of clouds the seeing was exceptional. I
could see the details on Mars disk also by visual
observation
It's only preliminary processing.
Processing details:
1, 609 frames captured by K3CCDTools
2, 375 best quality frames automatically selected
and stacked in K3CCDTools in X2 mode
3, Histogram stretch, gamma 0.9, unsharp mask (3,0,600)
in K3CCDTools
4, atmospheric difraction corrected by Registax 2.0
software
5, gamma 0.9, brightness-contrast-intensity (-4,9,0)

Mars 15.8.2001, 22:37 -
22:48 (20:37 - 20:48 UT)
Distance from Earth: 0.619 AU (93 million km)
Diameter: 15.11"
Altitude: 6.75° above horizon
Visible Mars movement during 11 minutes near the
star TYC 6820-80-1 (6.65mag). The Mars disk is
overexposed to allow to see the star (diffraction
spikes of secondary mirror holder around Mars
disk are visible). |

Diameter: 19.97"
Altitude: 13.6° above horizon
2X Barlow used
Stacked with K3CCDTools, processed by Corel
PhotoPaint (gamma adjustment + unsharp mask).
Resized to 200% after processing.

Diameter: 20.7"
Altitude: 14.5° above horizon
2X Barlow used+Blue filter
Stacked with K3CCDTools, processed by MaximDL
demo. Interesting is that usage of filter
enhances some details, another details are
suppressed. |

Mars 27.6.2001,
00:41 (26.6.2001, 22:41 UT)
Distance from Earth: 0.451 AU (68 million km)
Diameter: 20.7"
Altitude: 12.5° above horizon
Position low above horizont, lot of turbulence
influenced the quality of picture. But picture is
a little bit better than Mars on 20.5.2001 (above).
Picture was processed by K3CCDTools and Corel
PhotoPaint. |

Distance from Earth: 0.536 AU (80 million km)
Diameter: 17.44"
Altitude: 15.5° above horizon
Position low above horizont, lot of turbulence
and small aperture of telescope influenced the
quality of picture. But a few details are visible.
