Mars in year 2003



CalSKY simulator



Simulation by T.Ikemura Japan

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, 19.5C, humidity 67%
Processing: K3CCDTools + Registax 2.0 + Corel PhotoPaint

The 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) in Corel PhotoPaint


Place mouse pointer above the photo to see the labels.

Mars in year 2001

A. webcam at prime focus of 200mm (f=1200mm) Orion Optics Newtonian telescope:


Not overexposed Mars at the same scale

SkyMap Pro simulation
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 TYC6820-80-1 (6.65mag). The Mars disk is overexposed to allow to see the star (diffraction spikes of secondary mirror holder around Mars disk are visible).

Solar System Simulator

Meridian program
Mars 7.7.2001, 23:19 (21:19 UT)
Distance from Earth: 0.469 AU (70 million km)
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.
Note: Polar axis is rotated in the pictures.

Solar System Simulator

Meridian program
Mars 27.6.2001, 23:34 (21:34 UT)
Distance from Earth: 0.453 AU (68 million km)
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.

Solar System Simulator

Meridian program
Mars 27.6.2001, 23:27 (21:27 UT)
Distance from Earth: 0.453 AU (68 million km)
Diameter: 20.7"
Altitude: 14.5 above horizon
2X Barlow used
Stacked with Avi2Bmp, processed by MaximDL demo and Corel PhotoPaint (gamma adjustment + unsharp mask).

Solar System Simulator

Meridian program
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.

B. webcam at prime focus of 76mm (f=700mm) Bushnel Newtonian telescope:


Solar System Simulator

Meridian program
Mars 20.5.2001, 03:19 (01:19 UT)
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.
