February's '05 Centaurids |
|
|
|
|
ACE, OCE, TCE - no I am not talking about some new Singapore Highway.. but Centarurids (CE) - a = alpha, t= theta, o=omicron. Radiants are marked with 'X' . Can you find the Southern Cross - Crux? DVE=delta Velids |

<< - Unexpected Catch - I was hoping to catch
some Centaurids (ACE/BCE/TCE) using a wider lens 12mm lens (
see image below) but
instead caught a negative 9 magnitude
iridium flare (iridium #83?) as dawn
approaches.. on the left hand 6:45am. |
Then I find time to try something else...
| Found my Cokin filter during recent 'Spring cleaning'. It was meant for a camcorder 37mm filter size but with duct tape I mounted it to my video setup. A bw ccd is chosen for better spectrum line definition |  |

Spectrum .... |

| (Top) 'Sugar-Cane Stem' : Lunar Spectrum ( reflected sunlight of course!) Some identified dark or adsorption lines: A, B = Oxygen (O2) , C= Hydrogen (H), D2-1 Sodium (Na). - watec 902H ccd + 75mm f1.4 |
 |
| (Top) First attempt on Canopus - the second brightest star after Sirius. I am after the vertical absorption lines - at least a couple can be seen in this enlarged image. Mintron+150mm lens |
