Description

The result of first light with my new William Optics Zenithstar 73 combined with a ZWO ASI533MC-Pro. The scope was mounted on a Skywatcher HEQ5 Pro Synscan. The image was taken under a Bortle 6 sky using no filters (still waiting for my new IDAS NGS1 filter).

The sub-exposures were stacked in Deep Sky Stacker with a 2x drizzle. All post-processing was done in Photoshop. I use a proces heavily based on the Astrobackyard Image Processing Guide by Trevor Jones which I combined with my own workflow.

For a first attempt with a complete new setup, I am quite content. However, I do see that my stars are a bit bigger than I was aiming for, most probably due to my processing. I am interested to hear what you guys think. Let me know if you have any comments or tips & tricks.
