Mars Images 06-Sept-2003   Message List  
Reply | Forward Message #748 of 875 |

Some more Mars images. I am slowly getting the hang of taking
planetary images, but I have to admit that it can be the most tedious
thing ever in the imaging world. Anyway, I discovered that the fan in
the ST-237 was creating enough vibration to ruin (and I mean RUIN)
anything even coming close to a good image... so I disabled the fan.
The results can be seen at:

Notice the difference between the last four (newest) images and the
prior ones. No comparison there. So...off to sleep. ;-)
All were taken through the CN-212 at cassegrain focus with a 2.5x
Barlow. Images were then stacked using Registax (excellent sw).

My new slogan: Down with fans! ;-)

... I have wondered how vibration free fans could be made at affordable prices. The improvement in definition without the fan is quite marked. Now all you have...

Heheheh! Yep! You are right. Some day I'll get a webcam... for now, the b&w imaging of the 237 will have to do. Yes - I was really amazed at the overall trauma...
