All images in the Galleries below are originals by Rex Parker. They were taken from telescopes at my home observatory in Mercer County, New Jersey USA, or in Chile, South America. The main telescope at the NJ observatory (latitude ~40 deg N) is a 12.5" Cassegrain reflector (iDK made by AG Optical, f/6.7, FL 2130mm) on a Paramount-MX equatorial mount. The cameras in NJ over the past several years are CMOS sensor based -- ZWO ASI-2400MC, ASI-2600MM, and ASI-071MC astro-cameras. The images from Chile were taken with telescopes located in the Andes, since 2021 in the southern Atacama desert at El Sauce observatory (latitude ~30 deg S, elev 1525m). For the Chilean project, I am currently partnered with S Mazlin, M Hanson, S Foreman, and S Watson, using a 24" Cassegrain reflector with KAF-16803 CCD camera.
