KIC 02856960 spectrum
Posted: Mon Aug 10, 2015 11:16 am
With the RC600 of Mars Observatory we try to do the spectrum of KIC 02856960, (magnitude 16) But we had two problems :
- First : the native focal of the telescope at f/d8 and LISA spectrograph is close to f/d5, we can't use the RC600 with a focal reducer because of somme problem with the back focus of the telescope
- Second : The weather wasn't very good and we had only 3 exposures of 10 minutes for this spectrum, to low to have a good SNR.
Here's the autoguidage field
and during autoguidage
The result, very noisy.....
Next time we expect to have a better weather and try to fix the problem with the focal reducer.
