Broadband color targets - Iris nebula

June 7, 2019 - Reading time: ~1 minute

Yesterday I set up for a couple broadband color targets, and went with the Astro-Tech 6" f/9 Ritchey–Chrétien with 1350mm focal length. I paired the RC with the ZWO ASI071MC cooled color camera. And this is the first time I'll be using the DeepSkyDad Autofocuser AF1, which fits perfectly on the stock Crayford focuser--although you can't see it in this shot because I have the focus knobs vertical on the right site of the scope. Not using an OAG with this setup, but going with the William Optics 200mm guide scope and ZWO ASI120MM-S mono camera.

NGC 7023, Iris Nebula is a beautiful reflection nebula in Cepheus, about 1,300 lightyears away.
