Testing Testing Testing

 Testing the new Kit.

IC1396, The Elephants Trunk Nebula. So called because of the dark patch with a bright sinuous rim resembling the tip of the trunk. Yes you got to love where some of these names come from.. One star in this image (well actually three, two of which orbit each other every four days create violent out bursts of ultra violet radiation that strip electrons from the hydrogen gas and illuminate it in this wonderful colour. This in turn causes compression in the clouds of gas and starts star formation. The dark areas you see are the nurseries formed. 




This officially is the first target from the new set up. I spent the day setting up and balancing all seemed to go well and the guiding shown an RMS of just under .80. I am quite happy with this for a start. 3 minute sub frames were used and guided using the Altair Astro 60mm guide scope and ZWO ASI 1120MM for a total of four hours integration time.

The Optolong L-Enhance duoband filter was used using the ZWO filter drawer a fantastic and clever way to introduce and replace filters. 

Overall I am more than pleased with the new set up.
