Description

It is the first time I use my new Stellarvue SV60ED. This is a very compact refractor (25 centimeters long). I bought is to make visual observations of the Milky way and diurnal observations.

But I decided to try it on astrophotography, with the Photoline 0.79X reducer (F/D = 4.4) and ST8XME

The Rosette Nebula is 5000 ly far and belongs to the Persee Arm, the next one after the Sun's, which orbits in the Orion Arm. Its size is around 100 light years.

NGC2244 is the open cluster at its center and is made of very brillant stars. 2 of them are O type.

The yellow star (12 Monocerotris) a the center of the image is closer than the Rosette Nebula (500 ly). 12 Monocerotis is 50X brighter than the sun...

But the O star just below is a monster : 2500X brighter than the sun !!!
