First light with my Takahashi TAO 130 refractor taken at the ASV star-b-que weekend near Heathcote, Victoria Australia. I was very excited to see all the bits working with my new scope.

This is an image of Sharpless 2-308, an expanding bubble of ionized oxygen that has been ejected from the Wolf Rayet star in the centre of the image.

The image was made with 12 x 20minute sub exposures using an Astrondon 3nm OIII filter and using an Astro Physics 1100 gto mount.
