Imaging Planets
Imaging Jupiter with the CCD camera did proof not to be as easy as I thought. The camera is
easily saturated by the light from Jupiter. I had to buy more filters and I have to take the
right filter for the chosen focal length. This problem comes from the circumstance, that the
shortest exposure time is 0.6 sec, which is far too long.
The Mak 100/1000mm seems to be a good lens for planetary imaging.
Jupiter compositions from 5 March and 12 March 2001
The images were made under the circumstances described below. I had difficulties in finding
the sharpest position with the Mak lens. My old laptop I use does not show images on the LCD
good enough, so I will switch to my old 486/66 MHz again with monochrome monitor.
In the lower row you can see Jovian moon IO coming closer to the limb very quickly.

Saturn
- Instrument: f=1:10 Maksutov 100mm f=1000mm and M42 2 times
teleconverter projection. Estimated focal length is about 5 meters. All on NP
mount.
- Film: LcCCD 07
- Filter: Blue to get no saturation of chip.
- Exposure time: Composition of 30 images with 0.6 sec integration
time.
- Date: 12 March 2001, 19.50 UT
- Weather: Excellent, temp about +2°C, but seeing medium to
worse
- Note: I am not satisfied with this image; could have been better, but
it is the first.

Jupiter
- Instrument: f=1:10 Maksutov 100mm f=1000mm and M42 2 times
teleconverter projection. Estimated focal length is about 5 meters.
- Film: LcCCD 07
- Filter: Combined Blue AND Gray ND13 (=13%) to get no saturation of
chip.
- Exposure time: Composition of 30 images with 0.6 sec integration
time.
- Date: 05 March 2001, 21.04 UT (Same as in the compositions above)
- Weather: Excellent, temp about -3°C, but seeing medium
- Note: I made a bunch of experiments with imaging Jupiter and this came
out. Processed with IRIS. Astonishing for this small optics. The Jupiter virtual
diameter is 38". The GRF (Great Red Spot) is just goig around the limb on the
lower right.

Jupiter
- Instrument: f=1:10 Maksutov 100mm f=1000mm and M42 2 times
teleconverter projection. Estimated focal length is about 2 meters.
- Film: LcCCD 07
- Filter: Combined Blue AND Gray ND13 (=13%) to get no saturation of
chip.
- Exposure time: Composition of 50 images with 0.6 sec integration
time.
- Date: 05 March 2001, 21.35 UT
- Weather: Excellent, temp about -3°C, but seeing medium
- Note:Used lower magnification than above, but the image has not been
sharp.

Moon
- Instrument: f=1:10 Maksutov 100mm f=1000mm focal
- Film: LcCCD 07
- Filter: Combined Blue AND Gray ND13 (=13%) AND Green in front of lens
to get no saturation of chip, but it was still too bright.
- Exposure time: 0.6 sec integration time.
- Date: 05 March 2001, 22.13 UT
- Weather: Excellent, temp about -3°C, but seeing medium
- Note: I made only one short test with the moon - The Moon is too
bright and I have no more filters to reduce light.
