Deep Sky

I had tried out some deep sky images with my new camera, but was rather disappointed in the results. I know I shouldn't expect great results on the first try, but all the images showed some degree of movement of the stars. Either this was camera shake because of the action of the mirror moving, and me pressing the button (but I tried using the "hat" trick to avoid that and they were still there). Otherwise it could be the motors on the scope not tracking as accurately as I hoped.

Last night I decided to experiment, and tried the LPI, which was not designed for deep sky objects, on M42 in Orion. I was reasonably impressed with the results. With an exposure setting of just over a second, the results were quite good.

After a bit of post processing, the stars are obvious and there is even a bit of nebula glow.

Better than with the camera anyway.
