I've reprocessed my Western Veil data from Marfa using drizzle stacking and StarNet 2. The thin lacey appearance of the Veil allowed me to use more saturation enhancement than usual to bring out structural deatails in this super nova remnant.
The Western Veil Nebula (NGC 6960) with the Witch's Broom adjacent to 52 Cygni at the bottom. These filamentary nebula are remnants of a super nova explosion from over 5000 years ago. The Veil nebula is about 2600 light years distant. The dark skies of Marfa allow true color broadband imaging. I used a William Optics Redcat 250/51mm f/4.9 Petzval refracting telescope, Baader UV/IR cut filter, and ZWO ASI533 MC Pro cooled camera on a Sky-Watcher AZ EQ5 Pro mount. Imaging was controlled with a ZWO ASIAIR Pro astrophotography controller. This was my first use of multi star tracking with the ASIAIR and performance was excellent even with my tiny 120mm guiding scope. Image data taken 2021-06-11 from 07:30 to 10:30 UT with 3 hours of total exposure.
The extreme heat wave had daytime temperatures over 100F during the day and still in the mid 90s when the clouds cleared for my setup at midnight. As a result I imaged at -5C to keep the camera cooler unstrained.
59 of 67 3 minute exposure images were calibrated with a master dark, drizzel stacked, and processed in Pixinsight, StarNet 2, DeNoise AI, and PhotoShop.
