The Flame Nebula, designated as NGC 2024 and Sh2-277, is an emission nebula in the constellation Orion. It is about 900 to 1,500 light- years away. I shot this last month and was surprised to see a hint of the Zia Sun Symbol from the bright star Alnitak interacting with my camera pixels.

Some lunar images that I made at a star party conducted by TAAS at the Albuquerque Open Space Visitor Center on March 16, 2019. I couldn’t get my truck and heavy telescope equipment back onto the patio, so I self-deported to the overflow parking lot and set up. The seeing was unusually good, so I decided to do some lunar imaging along the terminator. I was joined by TAAS member Ben Thurmond. I used a C11 HD at f/10 with an ASI20mm camera equipped with an Astronomik ProPlanet 742 IR Pass Filter. In all cases, 500 frames were captured and the best 125 were stacked in AS!2. Wavlet sharpening was done using RS6. In all images, north is up.

This was with my low-rent Canon DSLR and the iOptron SkyGuider Pro camera EQ mount on a tripod setup. I was very happy with the amount of cluster nebulosity and surrounding dust clouds that were captured!

Details: Canon t5i modified, Canon 200mm lens, f/4.0, ISO 1600 Exposures: 2.5 hours of 60 second frames (actually took 3.5 hours and tossed 1 hour of the worst). Darks and Bias frames included, no Flats. Software: processed entirely with PixInsight.
