Uranus Image 2012/11/02(UT)
Stanislas Maksymowicz (305mm cassegrain)|
Here is the observation report for Uranus performed on the 2nd with the
305mm with rather average images.
There are 2 set of sketch (respectively at the same times):
- up: this is the compilation of the raw sketch and the dark edge effect of
the planet as it is expected.
- down: this the result of the observationnal report performed at the
eyepice so the raw data. The edge darkening is forgotten intentionnally
because the capture of the features near the limb on the darken ring is
problematic, more and more with the increase of seeing level.
The feature collected here are sure.
Globally the up set of drawings being a combination of raw sketch and a
disk with a darkening effect. This method may involve un-real feature near
the limb, except if a brightening is occuring with a non negligeable
This may involve more credibility at the 1st look but with uncertain
I prefer to issue still the down set of drawings that are sure.
