Social Media Images and SRO
We are continuously populating our social media with images from various astrophotographers at SRO. These clients are talented imagers from all walks of life. Some with no technical background, others skilled scientists, some who have written their own image processing programs, others who have constructed their own equipment. We hope you enjoy these social media links and the many images you'll see.

A Selection of Images from the Owners 16" RCOS/L-500 at Sierra Remote Observatories
The images below were obtained with Keith Quattrocchi's 16" Ion Milled RCOS Ritchey-Chretien telescope (f/9 with 3658mm FL) on a Planewave Instruments L-500 mount, and currently using a full frame ZWO ASI 6200MM CMOS back-illuminated camera and the Starlight Xpress AO (USB version). The autoguider is a Zwo ASI174. A Starlight Xpress 9 position FW houses Astrodon Gen 2 LRGB and NB filters. Focusing and rotation via Optec Gemini Focusing Rotator. A secondary Celestron 11" Edge is also present, using a Zwo L-OAG, Hercules Focusing/Rotator, and ZWO 7 position FW (2") with Ha/OIII and Hb/SII filters using a Zwo ASI6200MC, as a teaching tool and for planetary images. The autoguider is a Zwo ASI174Mini. The computer is a Custom PrimaLuceLab Eagle4 Pro (modified with 62 GB RAM and a 4 TB internal SSD). All images were taken from Sierra Remote Observatories.
