Before I send my LXD 75 mount for a service I wanted to have a go myself. Stripped & rebuilt, remounted and a perfect polar alignment later. I thought lets put the DSLR on and test PHD as it was tracking very badly (the fault of the mount by the way)and see what I get.
I wanted a target that was nebulous to also put to the test my new Lumicon 2" deep sky filter. Generally considered the best all purpose nebula filter on the market.With a transmission of 486nm Hydrogen-Beta @ 94%, 656nm Hydrogen-Alpha @ 92% & the double ionised lines of Oxygen III of 496nm to 501nm @92%. The Deep Sky Filter also passes infrared light, making it an excellent filter for photographing most deep space objects through light-polluted skies.
Enough of the tech stuff did it work?. The simple answer is the pic above. This Image was a 20 minute Phd guided exposure. My jaw hit the floor as everything performed flawlessly.
