Target: NGC3293 In Carina
Camera: QHY 8 OSC CCD
Exposure Capture: Maxim DL
Scope: GSO 8” RC
EFR: f/6.4 with WO F2 reducer
Mount: G11-G2
Exposure Setting: Prime focus
Exposures: 11 X 10 min 2 x 15 2hr 10min 19-20/12/2011
Seeing: no moon, slight wind, average seeing lot of moisture in air
Guiding: Orion Starshoot Autoguider using PHD with WO72
Focus: Bahlintov mask
Stacking: Maxim
Processing: Maxim, PS CS3, crop
Right Ascension 10 : 35.8 (h:m)
Declination -58 : 14 (deg:m)
Distance 8.4 (kly)
Visual Brightness 4.7 (mag)
Apparent Dimension 6 (arc min)
Discovered by Abbe Lacaille in 1751-52.
This cluster is another one of Abbe Lacaille's discoveries, made during his 1751-1752 journey to South Africa.
NGC 3293 consists of more than 50 stars in a 10 arc minutes field, the brightest of which is a red giant of mag 6.5, between many hot, blue bright stars (the hottest of spectral type B0). Rests of some nebulous material, floating between the stars which have probably formed from them. With an estimated age of only 10 million years, NGC 3293 is a very young cluster.
