 Part of the larger Veil Nebula in Cygnus, NGC 6992 is also known as the Network Nebula some 1400 light years distant. The Tzec Maun images were taken Aug.2, 2009. This BigMak image is H alpha (red), OIII(green), and SII(blue) composite. |
 Another image of NGC 6992 taken Aug.2, 2009. The AP206 image is RGB. |
 47 Tucanae (NGC 104), globular cluster, about 16,700 light years away from Earth, and 120 light years across. Visible with the naked eye–the second brightest globular cluster in the sky (after Omega Centauri). Image by Glenn Reagan using the HOU Perth R-COP (Remote Telescope Partnership: Clarion University, Oil Region Astronomical Society, Perth Observatory) telescope. |
 30 Doradus, originally thought to be a star, is the Tarantula nebula, an immense star forming region in The Large Magellanic Cloud. It is about 1,000 LY across, and 180,000 LY away. It is the most active starburst region known in the Local Group of galaxies. To give an idea of its size, if it were at the distance of the Orion Nebula (1,500 LY) from us, it would cover about 30 degrees (60 full moons) of the sky and would be so bright, it would cast shadows. It contains some of the most massive stars known and the closest supernova since the invention of the telescope, Supernova 1987A, occurred in the outskirts of this nebula.

Tzecmaun BigMak image of M8 taken August 23 2009. Red -Ha; Green – OIII; Blue – SII. |
 This 3-color RGB image was taken with the Tzec Maun Takahashi FSQ-106 apo refractor telescope using a SBIG STL 11000M CCD imager. With an f/5 focal ratio this telescope is great for larger images. Again NGC 6992 is the north eastern part of the Veil SNR complex. It’s a great image for the beginner. My exposure times for RGB were 7,8,8 min. Could easily go with 10,10,10 min because the scope has an autoguider feature. Taken Aug 15, 2009. |

 M8 – Lagoon Nebula taken June 26, 2009, by Glenn Reagan at the Hands-On Universe conference at Yerkes Observatory, Williams Bay WI, acquired remotely using the AP 206 Refractor at Tzec Maun Observatory in New Mexico. This image is a color composite made from 3 separate images with color filters. |
 Image by Glenn Reagan, HOU TRA-Teacher – Cordova High School Folsom Lake College – El Dorado Center – Sacramento City College, using the Tzec Maun Australian telescope, a Takahashi TOA-150 (6″) refractor, with a SBIG STL-11000 CCD and filter wheel. Operating the telescope remotely over the Internet, Glen took the images Friday March 1 in Pingelly, Australia (western Australia near Perth). Exposure times (RGB) were 3 min, 3 min, and 5 min. The image was processed with Photoshop CS2 using the ESA FITS Liberator plug-in.
